Hi

I am feeling very stupid now, but not sure where exactly to look. I
installed Lazarus using aptitude on Debian (under /use/libs/lazarus).
However, I see that that whole directory tree belongs to root. So if I
install a new package, how does it get added to the IDE (since I am running
lazarus as a normal user)? Should the installation not give the lazarus
directories to the users group instead of root? I suppose there is some
kind of magic involved that makes it work when recompiling the IDE with the
new packages, but I would like to understand what.

Thanks,
Chavoux

Message-ID: <CAPGeeiHL7KRa5BcOfPhjES8SB-VU8Bkr+w+DVo01pmN88ejGoQ@mail.gmail.com>

Second stupid question: Under options I can set the default Lazarus
directory. Is there a setting somewhere for default ppu (or unit source)
directory? I get an error when trying to install a new component (unrelated
to lazreport):
lazarus.pp(1,1) Fatal: Cannot find lazreport used by Lazarus.

However, I already compiled and installed the lazreport component (And can
see it on a tab among the other controls). My only guess is that the ppu
file was not created because of a permissions issue? Or else I need to set
the default directory for linking installed units somewhere?

Thanks again,
Chavoux

The IDE notices that the default directories are read only and puts the
files instead under ~/.lazarus/lib/.

No, that would be a security hazard.
Of course you can install Lazarus in your home directory as your user.
The debian packages are not made for that. You can for example use svn.

I just wanted to point out that in the 1.8 svn branch the docked sparta
form designer does not work with the gtk2 toolkit. A fix was issued in
October here:

https://bugs.freepascal.org/view.php?id=32199

But it didn't seem to make it into the 1.8 branch.

Message-ID: <bb3c778d-58b8-d8dc-12b0-aae4789bd175@freenet.de>

Does anybody know what the property "Marked" of TToolButton is good for? 
I never realized it, but it's been there at least since Laz 1.0, and in 
Delphi at least since D7. And it does not do anything, even in Delphi. 
Delphi's help 
(http://docs.embarcadero.com/products/rad_studio/delphiAndcpp2009/HelpUpdate2/EN/html/delphivclwin32/ComCtrls_TToolButton_Marked.html) 
says: "Use Marked to get or set whether the button is marked." What a 
nonsense! Then: "A marked button has a shaded surface. ". Well, in 
reality they look the same. And even if this were true what would be the 
difference to "Down" then?

Please create a bug report on http://mantis.freepascal.org and attach 
the patch there. Thank you!
Either I'll take a look at it later (I am leaving now for some time) or 
maybe some other developer.

According to the Microsoft documentation Marked is TBSTATE_MARKED.
Down is TBSTATE_PRESSED OR TBSTATE_CHECKED.
So they ARE different.

TBSTATE_MARKED is described as:
Version 4.71. The button is marked. The interpretation of a marked item is
dependent upon the application.

https://msdn.microsoft.com/en-us/library/windows/desktop/bb760437(v=vs.85).aspx

So it's up to the application to implement this. Just look at it as an extra
"option" for the button.

Hello,
Is it possible to run Lazarus as an application in IDE? I have a freeze 
somewhere, (Windows 10's "not responding" addition in a title bar).
A --debug-log doesn't help me much, because it is not flushed.
I know how to rebuild IDE, but don't know how to run it so that it can 
be debugged.
Thanks!

Open the lazarus\lazarus.lpi and run it.

This is <lazarus>/ide/lazarus.lpi, where <lazarus> is directory with 
whole Lazarus repo right?
Because my code I added there is not compiled. I added my files to 
<lazarus>/interfaces/lcl.lpk. When I build the IDE from tools menu, my 
code is compiled. But when I open the above-mentioned project, it runs 
but behaves differently.

Why did you add files to the LCL? That's quiet unusual.

Check Tools/ Options / Lazarus directory.
The lazarus.lpi runs the default lazarus.exe.

Hi,
I think the file is malformed somehow. Yes, indeed it runs the default 
Lazarus, but it is unable to build it. Obviously, it would be impossible 
to rewrite the running program. So someone could possibly fix the 
lazarus.lpi.
So I renamed the Lazarus.exe, then opened the renamed IDE, pressed F9 
and the "Program not found" error appeared.
I then tried to build with Ctrl+F9, and the following was written:
The project's compiler options has no compile command.
See Project / Compiler Options ... / Compilation
So how can I fix this? Or can someone fix the lazarus.lpi?
Thanks!

The lazarus.lpi does not contain the installed packages, so it cannot
build the IDE.
Use Tools / Build Lazarus to build Lazarus.

I guess you mean 1.8.0-1. 
Sourceforge has some trouble since a week.
Currently I don't see the 1.8.2 folders.

No. Every package has its own ppu directory.

Build Lazarus with -vt. See, if the compiler can't find lazreport.ppu or does not like what it found.

You lost me. How did you 'installed the lazreport and see it' with a

Subject: [Lazarus] Package and project file format
Message-ID: <alpine.DEB.2.20.1803031057110.322@home.telenet.be>


Hello,

The package .lpk andproject .lpi file use the following format :

     <Units Count="241">
       <Unit0>
         <Filename Value="lazarus.pp"/>
         <IsPartOfProject Value="True"/>
         <UnitName Value="Lazarus"/>
       </Unit0>
       <Unit1>
         <Filename Value="frames/oi_options.pas"/>
         <IsPartOfProject Value="True"/>
         <ComponentName Value="OIOptionsFrame"/>
         <HasResources Value="True"/>
         <ResourceBaseClass Value="Frame"/>
       </Unit1>


And similarly
      <RequiredPackages Count="7">
       <Item1>
         <PackageName Value="LazDebuggerGdbmi"/>
       </Item1>
       <Item2>
         <PackageName Value="LCLBase"/>
         <MinVersion Major="1" Release="1" Valid="True"/>
       </Item2>


Is it possible to get rid of the counts ?

Reason: if 2 people add files to a package/project, it always creates
conflicts when updating from the VCS. 
And if you're in bad luck, you need to change a lot of items.

On the other hand, if you do
      <RequiredPackages>
       <Package name="LazDebuggerGdbmi"/>
       <Package name="LCLBase">
         <MinVersion Major="1" Release="1" Valid="True"/>
       </Package>

The chance of conflicts becomes less, and the resolution easier.

Michael.

I am guessing the Count="xxx" attribute, and the numeric suffixes to
<Unit1> , <Item1> are there to read and write these files using
TXMLConfig class. Using TXMLConfig exposes an easy API to work with
XML files, but it limits what you can do --- all the children nodes
within the same parent must have a different name, so that you can do

File1 := XmlConfig.GetValue('Units /Unit1/FileName/Value');
File2 := XmlConfig.GetValue('Units /Unit2/FileName/Value'); ....

In Castle Game Engine, we added some extensions to TXMLConfig, in
particular TCastleConfig.PathElement to address exactly this. It
extracts a DOM element (TDOMElement) from TXMLConfig, and then you can
use full power of the DOM unit to operate on this element (iterate on
children etc.):
https://github.com/castle-engine/castle-engine/blob/master/src/files/castlexmlconfig.pas#L258
. This way you can still use TXMLConfig API (GetValue / SetValue) for
some tasks, but you can switch to using more powerful DOM API for
other tasks.

I thought maybe this is helpful :)

Michalis

+1
This has been a long standing annoyance for me too. XML, JSON etc don't 
need count properties... That's relics from INI file formats.

Well, I originally wanted to propose switching to JSON, but I thought that
might be stretching the goodwill a bit too much...

Hi,
+1 for this. And really it looks stupid to me to have a different tag 
for every item like Item1 or Unit1.

+1 for getting rid of unit count and numeric tag suffixes from XML 
project/package files. They always create trouble for version control.

-1 for switching to JSON. Seems radical and unjustified, in my opinion.

Thanks. Something like an additional boolean Tag, then.

Radical ? Absolutely. Unjustified ? A matter of opinion... JSON has many
advantages over XML.

Note that I didn't ask for that, it was just a remark on comments by someone
else...

If the counts are removed, my immediate goal (less conflicts) is reached.

Any chance of having the following bug fixed today so that i can 
continue debugging fpReport?

I will try.

It's not easy because its something that happens in the IDE. 
So I must be able to reconstruct it outside the IDE.

I guess you mean 1.8.0-1. 
Sourceforge has some trouble since a week.
Currently I don't see the 1.8.2 folders.

Thanks for fixing it so quickly!

Next in line holding further testing is #3308 
<https://bugs.freepascal.org/view.php?id=33308> (FPReport IDE designer: 
Handling of New/Open/Save proposal)

These 2 bugs are of lower importance than the above, but help make more 
testing:

#3305 <https://bugs.freepascal.org/view.php?id=33305> FPReport designer: 
Column headers/footers don't appear in preview when the page's 
ColumnCount is 1

#3304 <https://bugs.freepascal.org/view.php?id=33304> FPReport designer: 
HeaderBand and FooterBands properties of DataBand are not persistent

Whenever you have time for them...

Hello,
Sorry for possibly stupid subject and maybe off-topic question. In my 
UIA code, I am testing if a control has focus. So I have a FControl: 
TControl declared in my class.
Now say FControl contains a TForm1 instance, simply we have very simple 
program with just an empty window. Then an expression:
Result := FControl is TWinControl and TWinControl(FControl).Focused;
returns false. I am sure the form has focus..., because 
ShowMessage(BoolToStr(Focused)) returns -1, which represents true...

Hello and thank for a reply. Do I understand correctly that a form is a 
special case?
What about TEdit or TButton for example? I am encapsulating a TControl 
instance and am asking for properties needed for UI Automation, 
occasionally asking if the encapsulated control is a TWinControl instance.
I tested the simplest LCL program, just an empty form, and it really 
caused me headache. I just forcefully set the HasKeyboardFocus property 
to true for testing and the form was reported correctly.

I think there is some global service outage or something. I haven't been

SF had a move to a new data center a week or two ago... some projects are still 
having problems... i've only today just been able to update from numerous repos 
hosted on SF... it was surprising to a point...

Use MyForm.ActiveControl to get focused control on active form.

Hello and thank. And in general, if I have a TControl instance, can you 
tell me a reliable algorithm that tells me if the control has a focus? 
Only if it makes sense of course. So probably something like I tried 
before, that is the control is a TWinControl instance and the Focused 
property is true?
I know it doesn't work for a form itself. Maybe this is a bug?

By definition, the focused control is the control which receives 
keyboard input.
That's why the form in itself is never focused because a form doesn't 
handle keyboard input.
With just a form you may strike any key, and nothing will happen: the 
keyboard input is simply ignored.

The Form's ActiveControl property tells you which control has focus and 
will receive the keyboard input.

The control's Focused property tells you if the control has focus.

The focused control may be a button a TEdit, or whatever control which 
may perform an action upon striking a key.
You may push a focused button by striking the enter key or the space 
bar, you may enter text on a Tedit, etc.

Subject: [Lazarus] TFPRreport vs TFPJSONReport
Message-ID: <bf1016a0-22ed-fb44-c962-3a6a31a56136@gmail.com>

TFPRreport and TFPJSONReport need some clarifications. Maybe MVC can 
confirm/correct the below:

TFPRreport:
- Report design can be setup by code *only*.
- TFPReportData components must be linked to TFRReport by code
- Can invoke the IDE integrated editor to design reports and open/save 
them from/to file. But they are useless to TFPRreport.

TFPJSONReport:
- Report design can be setup by code.
- Can load/save report designs from/to file/stream/json (discarding 
design data if any).
- TFPReportData components have to be linked to TFPJSONReport by code 
(sample code is needed when the report is loaded from file)
- Can invoke the IDE integrated editor to design reports that are 
loaded/saved from/to the lfm only.
- The IDE integrated editor cannot open a report designed by the 
standalone designer, or save a file to be used by the standalone 
designer. Note: Actually it can currently open a file, but possibly with 
nasty side effects.

Not correct. You can load from file. See WIKI, I added a section on that.

This is always so, but:

The IDE contains a menu item in the component editor that
links the available datasets to the report to make this easier.

See also below for improvements in runtime.

Not correct. You can load the design from file. 
It doesn't happen 'out of the box' of course.

Correct.

They can also be loaded/saved to file, if you so desire.

It should definitely be able to open it. What happens with the data, 
this is up for discussion. Currently I am toying with the idea that the 
IDE offers to add the missing data definitions to the form.

I want to refactor the data handling a little so it can be used outside the
designer - as you noticed, when loading a design from file, the data
definitions are discarded. Then the loading in IDE can be improved...

Please look at the WIKI, http://wiki.freepascal.org/FPReport, I added some
explanations. I will add the 'Lazarus support' page after lunch.

Michael.

The magic is performed by Lazarus IDE, and by startlazarus.

If Lazarus IDE detects that your installation directory is read-only, 
when recompiling it will put the new Lazarus copy in your home directory 
(~/.lazarus/...)

When you launch Lazarus via startlazarus, it will check if your home 
directory holds a Lazarus newer than the one in installation directory. 
If such is the case it will launch your personal copy.

If you happen to update Lazarus, then the system copy in /usr/lib will 
be newer than your personal copy. In that case startlazarus will ask you 
which one you want to start. If you choose to launch the newly installed 
copy, the IDE will detect that your additional packages are missing and 
will add them to the list of required packages. Recompiling the IDE will 
add those packages and create a new personal copy, which now becomes 
newer than the system one, and you are properly set.

I can reproduce here:

You can shorten it to:
- in a new project click on filter in the object inspector
- press tab
- press o
- wait 1 second
*) List index (-1) out of bounds.

It's only a problem if you press Tab in the filter-edit and then press 
any key.

Message-ID: <em5c21776b-2686-4762-9a62-b2d8f73d7e4c@rolf-w10-mx200>

Does anybody know how to scroll a listview?
Seems that ListView.ScrollBy isn't working, at least not for Windows. 
There's no TCustomListView.ScrollBy procedure and of course the default 
TWinControl implementation doesn't send a LVM_SCROLL message to the MS 
ListView control.
Probably a bug?

Hi,
 
I found bug in Lazarus 1.9 (Lazarus 1.9.0 r57442M FPC 3.1.1 x86_64-linux-qt).
Properties of type Float are not streamed to *.lfm when theirs value =0.
It is not problem with for example TFloatSpinEdit where is "default" =0 (default means "value set in constructor" here, since floats cannot have default).
Some my components has "default" -100 and when I change it to 0, it is not stored.
 
Is it Lazarus or FPC issue? I'll fill bugreptort.

I think it's LCL bug. in demo, press button which copies MainMenu to 
PopupMenu and shows it.

Linux gtk2: new menu works like mainmenu.

Win10: new menu items don't work, menu item handler don't run.

The exception is fixed in trunk.

But I was under the impression that using TAB in the Component-filter in 
Object Inspector would set the focus on the TreeView with the 
components. It doesn't. I never use it but apparently it sets the focus 
directly on the Property view.

Is this the proper behavior (it was always this way) or is it supposed 
to go to the treeview?

Again, I never use the keyboard there so maybe it's supposed to be that 
way. In Delphi you can "Tab" into the Component Treeview but it hasn't a 
Component-filter-edit.

Any idea how to detect what/where is the source of the exception?

maybe there could be <> like on other lines in that IFDEF?
Not sure, just noticed little asymmetry.

I will zip it, but sure you have it. The code is one of the examples
installed with the standard lazarus 1.8.0

Gabor,

I can't duplicate your problem which probably implies that we are 
looking at some weird race condition during the program tidy up phase. I 
did see occasionally something like this before with Lazarus 1.6.4 on 
Windows with heaptrc - but I never saw it without heaptrc and it cleared 
up with Lazarus 1.8 and hence  I never bothered to pursue it assuming 
that it was a Lazarus bug that got fixed.

You are seeing this problem not so much with IBX, but with the Firebird 
Pascal API. Your example program has excluded the IBX part and focused 
purely on the API.

What might be an issue here is that the FirebirdAPI is accessed via a 
COM interface and the IFirebirdAPI interface is not explicitly released. 
The software just relies upon the system to clean it up at the end. 
There may be a race condition here between the clear up of the interface 
and the dynamic library manager. This is because when the interface is 
released, it then unloads the Firebird DLL/SO. Try adding a finalization 
clause to IB.pas setting "FFirebirdAPI := nil" and see if that clears it 
up - or whether the exception occurs before this point.

It is not obvious if there is a real issue with cthreads. The library 
should only create multiple threads when handling asynchronous Firebird 
events and your program is not using this capability.

Otherwise, yes, it would be really useful to be able to find where this 
exception is being raised.

To obtain meaningful information from gdb I do the following:
1) Compile both Lazarus LCL and fpc with debug info
2) Install the glibc-debuginfo packages
Otherwise you get only the information about exceptions which generate 
directly from your source code, which is many cases isn't sufficient.

Hope that it helps,

Giuliano

Giulian,

You may in a roundabout way have pointed me at where the problem lies. I 
always work with fpc debug libraries as well and I can't catch the 
problem. I changed to the standard release and the bug appears! 
Unfortunately, while duplicating the problem is one thing, tracking it 
down when your main debugging tool is unavailable is another...

Thanks to Giuliano mentioning debug libraries I have been able to 
duplicate the problem and to find the source of the bug - but it is as 
weird as it gets.

FYI: tests done on Linux Mint 18 with Lazarus 1.8.0 and fpc 3.0.4.

The evidence so far:

1. Gabor's program ends with an exception when using the FPC release  
RTL and FCL, but not when using RTL and FCL libraries compiled for 
debugging.

2. If I use GDB to step through the final steps of the program, the bug 
disappears!

3. If I add a delay at the end (e.g. a call to sleep(1)), the bug 
disappears.

4. Playing around with code optimisations and debugging flags seems to 
have no effect.

5. Using the age old technique of commenting out bits of the code until 
the bug disappears, I tracked the problem down.

In Gabor's program, the bug is removed by commenting out this line 
(shown in context)

       for i:=0 to SQR.GetCount-1 do
        begin
          case SQR[i].getItemType of isc_info_svc_line:begin
// s:=SQR[i].getAsString;  {This is where the problem starts}
                                                       end;
          end;
          if (s<>'') then WriteLn(s);
        end;

Going deeper into the fbintf package, I have further tracked the problem 
down to this line of code

SetString(Result,FBufPtr+3,len,CP_ACP);

FBufPtr is a pointer and it is fairly simple bit of code, copying a 
string from a buffer (received from Firebird) into an AnsiString. 
Commenting out the line stops the bug. The bug also goes away by 
changing it to

var s: string;
       i: integer;

...
  Result := '';
   SetString(s,FBufPtr+3,len,CP_ACP);
   for i := 1 to length(s) do
     Result += s[i];

which can only be described as a WTF moment. The problem has to be due 
to string disposal.

Finally, knowing all this, I go back to Gabor's program and add the line 
(again shown in context):

    repeat
       SQR:=SM.Query(nil,SRB);
       for i:=0 to SQR.GetCount-1 do
        begin
          case SQR[i].getItemType of isc_info_svc_line:begin
s:=SQR[i].getAsString;
                                                       end;
          end;
          if (s<>'') then WriteLn(s);
          s := '';                                             {Line 
added here}
        end;
     until (s='');

and guess what - bug goes away.

It looks like what is happening is that SetString is setting an 
AnsiString in such as away as to cause a problem when the memory manager 
cleans up - but only as a race condition and if the string is not 
cleaned up explicitly.

Looks like an FPC bug report to me.

A supplementary for anyone confused by the last extra parameter to 
SetString in the previous post (repeated below). When I wrote up the bug 
report, I should have gone one step lower in the code. The SetString 
commented out below is actually an internal function:

procedure TOutputBlockItem.SetString(out S: AnsiString; Buf: PByte;
   Len: integer; CodePage: TSystemCodePage);
var rs: RawByteString;
begin
   system.SetString(rs,PAnsiChar(Buf),len);
   SetCodePage(rs,CodePage,false);
   S := rs;
end;

However, the same result (e.g. the bug disappears) is achieved by 
commenting out the call to system.Setstring.

The key handling in OI is a little complicated. Now the TAB is also
handled in TObjectInspectorDlg.KeyDown().
I added commens etc. in r57490. Please debug and experiment with the
code. Maybe you can fix it.

Subject: [Lazarus] Special Request: Theme entire IDE support
Message-ID: <CAHmPLWV_LSdxfSkhQVX8=Qk-eewT87HNCOi-A+tRFa+oVnXN=w@mail.gmail.com>

I just wanted to put this idea out there, which I feel would bring
significant pleasure to a lot of Lazarus users.

Would someone consider adding or working on support to theme the entire
Lazarus IDE? I've found myself quite fond of darker themed IDE, such as VS
code:

Darker themed IDE example
<https://msdnshared.blob.core.windows.net/media/2016/03/vsc1.jpg>

As it stand Lazarus has already the ability to change the color of the
source code editor, and some support for changing the object inspector
colors, and message window colors, but all three of these customization
systems operate independently of each other. Also there are many other tool
windows whose colors or styles cannot be customized, such as the components
list in the object inspector, the project manager, and elsewhere.

An optimal solution would be to add a single IDE theme dialog allowing
users controls the colors and default sizes of everything in the IDE. Items
could be categorized in simple groups such as background color, text
color/size, highlight color, border color/size, and so on. Color and size
settings could be saved using a name, restored, and exported for others to
use.

I can think of a few ways this could be implemented, mainly through
offering a hook into the Graphics unit to redefine custom values for system
colors, and a flag to denote values have been overridden.

If anyone has desire to communicate the pros/cons of this proposal (both of
the concept and implementation) could you please it discuss here?

Big problem with scrollbars: Treeviews, Listboxes, Listviews, Synedits. 
I made big work to theme scrollbars in CudaText.

Ralf, I believe your response was to to dark screenshot. I was hoping
people would not consider one particular style and judge customization one
that, but rather the idea of making customization of colors and size user
accessible.

Regarding completeness of custom colors and themes, yes some items may not
be easily themed, such as scrollbars. IMO though an attempt would not have
to 100% complete at that start. That is, creating an simplified way to
change some or most of the colors and size would be a good start.

Hi,
 
you can do it for Qt applications, just run Lazarus (or any Laz. project built as Qt) as:
 
./lazarus -stylesheet mydarkstyle.qss
 
where mydarkstyle.qss must be valid Qt Style Sheet file, see: http://doc.qt.io/archives/qt-4.8/stylesheet.html#stylesheet

But again I've found scrollbars problematic since they look ugly when 
they're completely drawn by stylesheet :)

Hi,
 
DoContextMenu(...) cannot work, this method only manages OnContextPopup event.
Perform(LM_CONTEXTMENU, 0, 0) (or SendMessage or PostMessage) works here (Qt). Handle must have assigned PopupMenu and it needs correct parameters, not just (...,0, 0) which shows Popmenu in the top-left screen corner here.

I thinked about how to replace LCL scrollbas with ATScrollbar. Ie some 
LCL change which hooks SetScrollInfo too. Maybe it's possible to create 
ATScrollbars instead of OS bars and change them by SetScrollInfo. And 
change ClientRect of control.

Subject: [Lazarus] Suggest LCL refactor for ShowContextMenu
Message-ID: <e916a8df-035d-5e13-3a01-054c023e9251@ya.ru>

Maybe it's good to have LCL method to show context menu, w/o using 
Perform(LM_contextmenu,...). Name it ShowContextMenu(X, Y) - method must 
be main part of TControl.WMContextMenu


procedure TControl.WMContextMenu(var Message: TLMContextMenu);
var
   TempPopupMenu: TPopupMenu;
   P: TPoint;
   Handled: Boolean;
begin
   if (csDesigning in ComponentState) or (Message.Result <> 0) then Exit;
   P := GetMousePosFromMessage(Message.Pos);
   // X and Y = -1 when user clicks on keyboard menu button
   if P.X <> -1 then
     P := ScreenToClient(P);

   Handled := False;
   DoContextPopup(P, Handled);
   if Handled then
   begin
     Message.Result := 1;
     Exit;
   end;

   TempPopupMenu := GetPopupMenu;
   if (TempPopupMenu <> nil) then
   begin
     if not TempPopupMenu.AutoPopup then Exit;
     TempPopupMenu.PopupComponent := Self;
     if P.X = -1 then
       P := Point(0, 0);
     P := ClientToScreen(P);
     TempPopupMenu.Popup(P.X, P.Y);
     Message.Result := 1;
   end;
end;


so WMCOntextMenu will be some checks + getting X/Y + call to new 
ShowContextMenu(X,Y) + Message.Result:=1.

You can also just use a filestream ?

It's merely debugging code. I changed it so you can hunt your bug.
Keep in mind it can change any time.

I think the issue with this is that some elements use pictures with fixed
colors, and some elements do not honor style settings (like the TreeView in
the component editor, which always has a white cell background).

A complete list would be helpful. Perhaps searching for instances where
colors are set directly?

What about the colors that have no counterpart in graphics?

Lazarus would become unresponsive after trying to add a new menu item using
the Menu Editor. Don't know what the problem was. Got around it by manually
adding the menu item by editing the .LFM file while Lazarus was not running.
Also added the declaration and procedure body for the Click event in the
.PAS file. FPC compiler ate it up, and the new menu item's event fired as
expected. Lazarus was then able to modify the new menu item as expected.
Version 1.8.0 32/64 bit on Windows 8.0.

Creating the database and table employee wasn't "just in case".
It was a requirement if you want to use that example with sqlite.
http://wiki.lazarus.freepascal.org/SQLdb_Tutorial3#Getting_database_data_into_normal_controls

And surely you changed something (like the .ini) otherwise you end up 
with Firebird db connection.

So zipping your project (with the database) is still best.

Tip: You are sure sqlite3.dll has the same 'bitness' (i.e. 32 of 64 bit) 
as your executable?

Subject: [Lazarus] TStringGrid and cancelling a modal form
Message-ID: <p86d76$frp$1@pye-srv-01.telemetry.co.uk>

Running on (Debian) Linux on AMD64 or ARM, Lazarus 1.6.4 and FPC 3.0.2, 
I'm seeing different behaviour depending on whether a program uses Qt or 
GTK2. The program changes the hardware configuration of a mouse 
(Logitech G600) using hidraw, and as such needs to run with root 
privilege (e.g. kdesudo or sudo -E).

On the main form I've got (a tabbed notebook containing multiple 
instances of) a TStringGrid. The OnSelection event invokes a modal form 
(containing nothing of significant complexity) with OK and Cancel 
buttons, and stripped down looks like this:

procedure TFormLG600.StringGridMode1UnshiftedSelection(Sender: TObject; 
aCol, aRow: Integer);

begin
{...}
   if ButtonsAndKeys.ShowModal() = mrOk then begin
{...}
   end
end;

This is fine if built for Qt, but if built for GTK2 what I see is that 
after the modal form is exited any mouse activity over the grid appears 
to cause an erratic multicell selection and the modal form immediately 
pops up again. This is reproducible if the Cancel button is pressed, and 
in at least some cases after OK.

I've seen indeterminate discussion of this in the foramina, and have 
followed up the indicated wiki pages etc. Does anybody have any 
suggestions, preferably not along the lines of "don't use GTK2" since I 
was thinking of sticking this on Sourceforge and that restriction would 
probably be unpopular?

hmm, try LCLIntf.SetCapture(0) after closing modal form , just to 
isolate capture problems.

Hello,

Just for testing the OnSelection is raised by mouse click ? If the 
answer is yes, try to click the cell and keep the mouse button pressed. 
If the form appears the grid is still waiting for a MOUSE_UP (thinking 
you are holding MOUSE_DOWN to perform a selection) and the modal form 
has its own queue, so MOUSE_UP never arrives.

Like this?

}  end

;  LCLIntf.SetCapture(0)

end { TFormLG600.StringGridMode1UnshiftedSelection } ;

No obvious change- what should I be looking for?

Yes, the modal form appears while the mouse button is held down (for 
both GTK2 and Qt).

I like darker themes too - much easier on my eyes. Hence my eyes bleed 
[not really] when I look at Windows 10.

If somebody was to complete the LCL-fpGUI widgetset (so you can actually 
compile the IDE with LCL-fpGUI), then you could simply use the dark 
themes included with fpGUI and your solution is done. ;-)  fpGUI 
applications can apply application specific themes and not depend on 
desktop environments. They can be switched at runtime too.


For examples of those dark fpGUI themes, see the Carbon or Plastic Dark 
themes shown here:

    http://geldenhuys.co.uk/~graemeg/themes/start.html


I would imagine that the LCL-Qt interface could do the same, as that 
shouldn't depend on a desktop environment.  Or does it?

Regards,
   Graeme

Graeme, thanks for the feedback.

To everyone, I already have a plan for a basic theme system for all
platforms which I'll be publishing as a design time package soon. It will
work using text theme define files, and apply properties values to
everything in the IDE using a pattern matching system with groups. It will
search for published properties of all controls inside the IDE, changing
them to the values specified in the define file. It will also provide a
preview of changes to a select group of controls such that you can preview
a theme by clicking on its name from a list of available themes.

The drawback to this approach is that some elements in certain toolkits
aren't themeable using strictly property values. Scrollbars are one example
already mentioned, but this problem also applies to some buttons, toolbars,
page tabs, and I'm sure a few other things. But I think this will the best
that can be hoped for given the current design of LCL controls.

I do have a plan to allow for theming of icons/glyphs inside the IDE,
including the menu, tree view, and component icons. All revertible of
course.

Finally, I believe the proper solution to a fully themeable IDE would be to
use custom painted controls for the entirety of the IDE. It wouldn't really
be that hard. I've coded my own tree view, list view, edits, buttons, menus
and such from scratch on a few platforms. It would be more portable as
well. It's just a bit tedious. If implemented it probably should use a more
advanced graphics subsystem that does not mimic plain old GDI/TCanvas. I'll
leave that someone else someday.

Graeme, I looked at some on your fpGUI screenshots and some are quite nice.

What's the compatibility level of your controls with LCL controls code
wise? Also, what graphics API are you using for different platforms? For
example have you implemented a common advanced graphics API bridging Cairo
on GTK, Direct2D on Windows, Quartz2D on OSX, and QPainter for KDE?

Is there a portable way this can be sent? Otherwise I presume I could 
fudge it with something like QueueAsyncCall()... unless that also went
through before the mouse activity was sorted out.

I'm fairly keen to hack this in such a way that it's not tied to one 
version of the LCL since I want this program to be fairly easy to build 
even for people with an old (or no existing) copy of Lazarus etc.

Hello,

I think the proper solution is to instruct GTK2 to use the MOUSE_UP 
event, but meanwhile QueueAsyncCall will not be the solution as when the 
AsyncCall will be processed grid will be still waiting for MOUSE_UP, so 
my solution would be add a MOUSE_UP and MOUSE_DOWN handlers, something 
like this in pseudo code:

MOUSE_DOWN:
   SelectChanged:=false;

ON_SELECT:
   SelectChanged:=true;

MOUSE_UP:
   if SelectChanged then Form.ShowModal();

I don't think this is a good idea.

If you do this, then you're again offsetting a real solution by years by
providing a half-baked solution that maybe satisfies an itch you have now, 
but fails to provide a long-term solution.

So if you do intend to make an effort (and I realize it is one), 
please do it on a lower level, namely the LCL. That can mean making fpGUI
widgetset really usable for the IDE, or the customdrawn widgetset, or
something else.

But at least then all applications can benefit from the effort.

There is nothing wrong with having vision and a long-term plan.
But yes, it does take perseverance and resisting scratching an immediate itch.

Michael.

Thanks, I'd just about worked that one out. I'll try later- I'm spending 
the day helping with some flocking sheep ;-)

I mean "Just in case" not to get the TStringGrid properly filled, but to
get an exception like "Table not found", not a "SIGSEGV exception"

No, the default is still firebird, and it woks fine. Well, it doesn't
work because employee doesn't exits, and I get an "Database not found
exception"
I select on propose sqlite3. and I get SIGSEGV  with no more clue in the
Fquery.open

Well, it is the dll I use for some old delphi 32bits utilities.

My point is if I'm missing some package, or the dll should be in other
path, or a hint how to dig and debug deeper, beacuse I can't debug into
open.

No, the SQLite3.dll and your DB should be sufficient.

Could you include your .ini file and your SQLite db?

Normally the firebird employee database is in
C:\Program Files\Firebird\Firebird_2_5\examples\empbuild\EMPLOYEE.FDB
(which you can copy to another location so you can access it)

But for SQLite you'll need to create your own DB with the correct table 
and content.

Michael,

I agree with you somewhat that my proposal isn't a total solution, but
perhaps there is another point of view to consider that has been
overlooked.

And that is this:

There ought to be a way to edit component properties sweepingly either in
an application or in the IDE.

I say this because I have often edited the Lazarus source to make remove
toolbar button captions, change edge borders, fix the position of edit
boxes, increase the height of a panel, turn on tool tips. or remove an
unneeded panel. All for the effort of adjusting layouts to make the IDE
space more efficient, fix what I see as a design problem, or create a
layout better suited to a personal taste.

Allowing anyone to easily make sweeping changes like these to the IDE, and
making those changes easily shareable and modifiable without the need to
search for the correct lfm, or pas file to edit and recompile the IDE would
be a good thing. That is, imagine being able to group alter properties of
controls/components within the IDE (or any application written with
fpc/laszarus), and see those changes instantly, and easily reverted,
without the need to search for files and rebuild.

As such I think that there is merit to such a tool. It might not need to be
branded as a "themer" or "skinner". Perhaps as a "property pattern editor"
or something thereof.

Regarding a long term solution, I agree that would be best. What I would
see as the optimal way to handle this would be to use entirely owner drawn
controls based which depend on external resource files, to determine styles
such as color, sizes, padding, font, alignment, glyphs, and visibility
among a few potential possibilities. Actual control drawing would be
handled through an abstraction layer to a platforms best possible graphics
API to efficiently handle antialiasing, smoothing, subpixel, and hdpi
rendering in a manner that makes it complete transparent to controls. This
would allow one code base for all controls for all platforms, solving not
only layout problems among different widget sets, but also behavioral
problems that creep into usage due to difference or restrictions of the
underlying native widgets.

Of course, such a design should be completely optional to allow people to
continue using native controls whenever they want, but if they're
interested in a totally themeable and consistent usage applications across
all platforms, then using this alternate widget set would be a pleasant
second option.

Thanks. Finally it works. I created the table employee and set the full
path of the file.

Nevertheless, it looks that sqlite3 is a little... well... sending
SIGSEGV is not a valid error, "cant' find file", "table doesn't exits"
etc would be much better.

I would like to dig a little and try to improve error detection. Is
there any way I can debug into open?. I've tried compiling Lazarus IDE
with debug, but skips over "open" call. What should I compile in debug
mode to parse FQuery.open?

I take it you already activated the debugging options (which were 
disabled in your published project). Otherwise you wouldn't even be able 
to trace to the Open line.

Next problem is that the database sources are not part of the Lazarus 
IDE. They are from FPC. So you would need to recompile the complete FPC 
to be able to step through it. (Recompiling Lazarus IDE only compiles 
the IDE part with debugging information)

I use the trunk version from my own script but you could use fpcupdeluxe 
to install a development version, in which you could trace through the 
whole source. http://wiki.freepascal.org/fpcupdeluxe

Here, I get the correct and expected warnings/errors when using the 
SQLite3 driver (in both Lazarus 1.9 and 1.8.2). SQLite will 
automatically create an empty database if it does not exist. After that 
it should warn about the absence of the employee table.

I believe this is the aim of fpGUI and the customdrawn widgetset.
That is why I proposed extending them to the point of usability needed for
the IDE.

Agreed.

My main concern is more "strategical":

Our time is limited (and by "our" I mean you too).

This "property pattern editor" - while it definitely has reasons for existing - 
will provide something halfway decent (because it can never do everything
required for proper theming), and will most likely divert attention/time 
from the root problem...

But it is obviously a free world, I can only point out a concern I see...

Hello,
 
I noticed that wiki pages http://wiki.freepascal.org/Lazarus_Application_Gallery and http://wiki.freepascal.org/Projects_using_Lazarus become too comprehensive and therefore obuscated. Especially the second should/can be separated to more pages - Components and Libraries, Multimedia, Games etc. because it is well separated in content of the page. No idea how to separate Application Gallery. Alphabetically?

hehehe... And everything you mentioned there is already supported in 
fpGUI. fpGUI is a 100% custom drawn toolkit, with no 3rd party library 
dependencies. It includes a 100% Object Pascal based 2D rendering engine 
(called AggPas) which does anti-aliasing, and high quality sub-pixel 
rendering. fpGUI already supports theming - via code or external image 
resources.

The only part lacking from your wish list, is the LCL-fpGUI widgetset 
implementation. A lot is already working, but it still needs a bit more 
work to get the Lazarus IDE to compile with LCL-fpGUI.

   Graeme

fpGUI's controls can not be mixed with LCL controls. But the LCL-fpGUI 
implements a bridge between the two, making fpGUI controls behave like 
LCL developers are used to.


> Also, what graphics API are you using for different platforms? For

Both. fpGUI v1.4.1 talks directly to the underlying OS platform's 
graphics API. That's Xlib for X11 based systems, GDI for Windows/WinCE 
etc. You as a developer don't need to worry about the differences, 
simply code using the TfpgCanvas class and the framework takes care of 
the rest. This also means fpGUI applications run pretty much everywhere 
without needing installations or megabytes of 3rd party libraries and 
DLL's (eg: Qt, GTK libraries are huge).

The "develop" branch of fpGUI does the same as before, but also has a 
new option... AggPas, which will become the default canvas and 2D 
rendering API. It is 100% platform independent, because it is 100% 
implemented in Object Pascal. And as I already mentioned in my other 
reply, it does anti-alias sub-pixel rendering as standard. It also has 
the ability to read TTF font files directly and thus incorporate high 
quality text rendering in the output too.


Regards,
   Graeme

OI and other special IDE windows should indeed support theming. Now
they have fixed colors.
However LCL itself already supports theming because it maps to native
widgets. The native style + theme is used.
It means you should change a style for your entire desktop instead for
Lazarus alone.

LCL has some complex components like TreeView which are custom drawn
instead of native. Theming for them must be implemented using the
theme services already included in LCL.
Adding an external theme support for LCL apps sounds like a very bad
idea. It would combine the bad parts of a custom drawn and native
widget libraries.
Mapping to native widgets is a clear design decision which has both
pros and cons. Custom drawing everything is another design decision
with its own pros and cons.

Or, maybe there is something about this issue I don't fully understand.

It follows native theme of the widgetset, but not eg color setted up 
from lcl (well, Qt can handle that but not for mswindows and cocoa 
themes). I think that Alexey wants to customize scrollbars (eg with 
different color), but he cannot do so with lcl TScrollbar which is 
native widgetset control. Same as you cannot set TBitBtn.Color under 
win32 ws.

Juha,

Thanks for the info about tree views. I had attempted to alter the theme on
Linux with Qt4 widgetset and a stylesheet argument on the command line and
I noticed the tree views were not taking on the styles I defined. I think
they probably need to be adjusted to respect system colors at the minimum.

Regarding changing the OS theme to change the application theme, in some
cases this is undesirable. For example some paint type programs, and even
some code editors, use their own independent theme to subdue their interface
<http://cache.getlazarus.org/images/photoshop.png> making the work more
prominent. In these types of situations it's not reasonable to retheme the
entire OS, rather just retheme an individual application. And of course in
these situations an application theme is often a matter of personal taste,
so the actual styling should be externalized. What we're left with is the
logical solution, to support application level user defined theme
information in external styling files.

Ok, I understand.
I am not against such theming if somebody implements it.

Obfuscated for doing what?
It's a long list of mostly independent projects.
Maybe tagging them would help.

I don't see how splitting the list alphabetically helps.

Wow, you found a bug! Please report.
It happens if any function call is following the line where you try to
insert parameters, not only with Application.Minimize call.
You did not mention your Lazarus version. I can reproduce at least
with Lazarus trunk.
Is it a regression? Did it work earlier? What revision broke it?

It does not check, if the parameter is compatible.
It sees 
pos( something.something;

It changes:
  sl := TStringList.Create;
into:
  pos(
  sl := TStringList.Create, v2);

which can never be right.
I think a newline should break searching for existing parameters in this case.
When a user wants to insert template parameters, he typically has no
existing parameters at that point.
If he has existing parameters, then he uses Ctrl-Space and
Ctrl-Shift-Space to modify / verify them.

True. Feel free to improve the heuristic.

Maybe better: "when the closing bracket is missing, a newline should
break".

You can't use Ctrl-Space to add v2.

I've made that argument over 12 years ago to the Lazarus team, and every 
few years after that. They shot me down every time. Initially I wanted 
to use LCL and Lazarus IDE for enterprise based commercial software. All 
my clients wanted own styled applications - separate from the OS. LCL 
couldn't deliver [and for some more reasons] I had to leave LCL behind. 
I then implemented a whole new toolkit (and partly for fun and learning) 
to accomplish cross-platform development with FPC and that allows 
individual applications to be fully themeable.

I'm glad to hear that LCL finally has some sort of themeing interface, 
but based on these discussions, I guess it is not working 100% for all 
LCL based applications. At least the project is heading in the right 
direction.

   Graeme

MarginNNN and MinMarginNNN and PageWidth, PageHeight. Currently set to

Subject: [Lazarus] Help: What color group is this?
Message-ID: <CAHmPLWWazNahmQatW6kM3ZBnhAm9WnrmyfDecKmMWwkWn+PSuA@mail.gmail.com>

I am trying to create some alternate styles for Lazarus and its code editor
but am having a problem identifying some elements.

Can anyone tell me what element group to which these belong?

http://cache.getlazarus.org/images/code-color-problem.png

These elements appear when you put your cursor on an identifier and code
tools automatically highlights all identical identifiers within the same
scope.

I've tried changing all colors in both template and sycrhon edit, but they
have no effect. I'm beginning to suspect that the color values are hard
coded somewhere. Does anyone know where these colros values they are set or
if they can be modified through the IDE display colors dialog?

Thanks

"Text" > "Highlight current word"

You can also go to "Markup and Matches", and behind "Disable timer for 
markup current word" press "edit color"

its not "scope" but "entire file"

Probably you're using Qt5 lib < 5.6. AFAIR Ubuntu 16.04 have Qt-5.5 by 
default (same as mint 18.3), I've successfully installed Qt5 5.6.1 from 
some ubuntu repo and it works like a charm.

Message-ID: <CAOWTWzqBj2LnS1Y53rXB23oxakPto=9ntpSOvtKDrOTSDz8igQ@mail.gmail.com>

Hi,

my application uses DB grid and when user hit and hold pgdown/pgup, or
hit CTRL+Home/End, applicaiton always crashes. Gdb gets this
information:

Do you have any idea what could be wrong, please? Thanks!

Lazarus 1.8.0, fpc 3.0.4 Ubuntu 16.04, Ubuntu 17.10, the same problem
with Lazarus 1.6.x in Fedora/Ubuntu/Debian etc.

Not in the LCL itself. Maybe you can try to build one using 
http://wiki.lazarus.freepascal.org/mbColorLib#RGB_color_pickers

I didn't use it myself, it just popped up in a Google search.

Hm. I didn't find that. Must have used the wrong terms. 
However, none of them seems to support Alpha.

It looks like I will have to make one myself :(

I did the port to Lazarus. But no - none of them supports an alpha 
channel, they focus on color selection based on a variety of color 
models. Maybe you should have a look at BGRABitmap and associated controls.

Looking at the demo of the mbColorLib again after some time I see now a 
terrible flicker on Windows. Ondrej, I fear your change in 
double-buffering killed a majority of third-party components. It may 
take some time until all authors will fix this (and most of them left 
their babies...).

Hello,
 
native TColorDialog in Qt4 has slider and edit for Alpha channel but this value is never in the result (i.e. TColorDialog.Color property). TColor uses upper 8 bits for other purposes than alpha.

I've written a pascal version of some color controls which I've ported to
Lazarus. Here is a link to a page with demo video:

https://www.codebot.org/delphi/?doc=9524

These controls includes a hue picker that has 2 styles (radial as shown and
bar), a saturation pick again with 2 styles, and an alpha picker. I also
have a color value slider edit box, where you can type out a R, G, B values
in bytes or floats, and it has a drop down with a left right slider that
shows you the colors.

They should be enough to create a decent pascal native color picker. Quick
example, adding the alpha picker and drop down edit is trivial:

This is exactly what I meant by "you can try to build one using ...". It 
shouldn't be that hard - just use the color picker you like (e.g. 
THSColorPicker) and put a spinedit next to it for the alpha channel value.

Since I don't want dependencies on other packages - only the LCL can be used 
- this is not an option...

Why killed? You can still set the DoubleBuffered property to True.

In 1.8 the DoubleBuffered property was ignored on Windows for all 
controls. Instead DoubleBuffered=True was forced without the chance to 
disable it. I.e. the property was absolutely useless since it is not 
used on Linux/OSX either.

I just disabled the forced DoubleBuffered=True - the same what Delphi 
does. The only thing LCL misses is ParentDoubleBuffered that makes 
things easier.

If you don't like the Delphi way but like the Lazarus 1.8 way - it's a 
valid scenario as well, but then the DoubleBuffered property should be 
deprecated/removed and DoubleBuffered should be handled automatically 
with protected methods to override the default behavior.

If you want to discuss it, it will be better to open a new thread.

Qt4/Qt5 ws have alpha option in standard color dialog.

That's no good to me. It needs to work on all platforms, all widgetsets.

This is lazarus, after all - it should work on all supported platforms.

Unfortunately LCL always uses native widgets - including dialogs. 
Non-native and custom widgets (that are not in the VCL) are left for 3rd 
party vendors. The Lazarus CCR (where mbColorLib is hosted) is a good 
place for such 3rd party custom components. E.g. virtual tree view and 
fpspreadsheet are hosted there as well. I am sure you can get commit 
rights for it if you want to improve libraries stored there.

If you like to write your own alpha channel color dialog (based on 
mbColorLib or not), you are welcome to host it on LazarusCCR as well.

I need it for FPReport, meaning it must be in Lazarus itself, so I will
write a minimalistic dialog that supports Alpha and include it in the report
designer package.

Yes, that makes sense. In Lazarus itself the same problem is solved by 
selecting the color and alpha channel independently:



But I am aware it doesn't need to suit your needs either.

Subject: [Lazarus] Beep?
Message-ID: <35147946-a2ef-3aa1-492d-23e20107e57f@ziesig.org>

Hi Everyone!

I am using Lazarus 1.8 on Linux Mint.  I would like to use the 
Windows.Beep( Freq, Duration) function, or (if not available) 
SysUtils.Beep subprograms.

Simplest problem.  SysUtils.Beep compiles and links but is silent.

Slightly more difficult (according to StackOverflow)

I should be able to insert (manually) Windows in the uses clause, then 
call the windows.beep( f, d) function, but fcp can't find Windows even 
though there are several windows.pp files in the fpcscr directories.

Failing that, the article says:

|functionBeep(dwFreq,dwDuration:DWORD):BOOL;stdcall;external'kernel32.dll';|

should work, but it causes a linker error after compilation.  I don't 
have lernel32.dll on my Linux system.

A long time ago, I used the Windows.Beep (on windows) to produce Morse 
Code error messages while debugging visual components.  I would like to 
do that now if possible, but on Linux.

Any suggestions would be appreciated.

Thanks,

Don Ziesig

AFAIK, you can not call Windows functions in Linux.

Hey guys. I wrote this web tool a while ago which emulates a desktop
application in a few ways and wanted some feedback.

http://storage.codebot.org

login: tester
password: funkytown

The tool is a private cloud file server application. People will be able to
get the source and configure it on their web server so that they can
backup/share/transfer files to themselves or among friend. The admin
account can manage users, their rights, and storage limits.

What I've tried to do with this app is emulate a desktop application a bit,
which might be similar to a desktop app written with Lazarus.

Features:

You can drag and drop files or click to browse for uploads. Large uploads
can be resumed if you close the page before the upload completes. Uploads
can be paused and resumed.

The selection in file list can be navigated with up down and page up down
arrow keys. Shift multi selects both with the mouse and keyboard. Control
can toggle select on individual items.

Some files including video and audio can be viewed. It has code for http
stream allowing seeking to positions in large video files without the need
to download. Multi select can be used to create play lists. If you select a
group of songs, then open the song and play it will continue playing the
next song when the current song is done.

Enter selects items/ Function keys F2 renames inline, F3 search filters, F4
gives the option to turn sharing on/off (works with multiselect). File
columns can be sorted.

The front end code was written using my own typescript library.

Any feedback would be appreciated.

Nice interface.

Some points:

Wrong password doesn't gives an error, simple ignores it no "Invalid
user or password".

Downloading videos is not posible. When I tried to reproduce it I got an
error "No compatible video mime format", Maybe my browser fault, but
couldn't dowload it either.

I suppose this is realtaed to freepascal some way. Isn't it?

Santiago,

Thanks for the feedback. Regarding the failed login, my initial though was
to not add a "Failed login" dialog for security purposes. That is to not
tell people why nothing happened in an attempt to better secure your files.
Several people have already mentioned this problem, so I may add a failed
login dialog or message.

Regarding the Lazarus connection, I frequently post here about fpc and
lazarus, but also sometimes post other programming work if I feel it
overlaps with Lazarus. In this case I am attempting to write a webpage that
acts like a desktop app, something for which I'd always use Lazarus as my
first choice, that is desktop development. With this app I've made some
efforts to carry over desktop user interactions. Shift and control click
selection, some dialog looking things, inline renaming of files, arrow key
moves the current selection, and what not. As such I am interested in the
feedback of desktop developers and thought lazarus people might have a
perspective I wanted for feedback.

Anyhow thanks for your opinions. They are appreciated.

Bad:

1) The webpage is fixed width, or has a minimum width.
2) I can't view videos, but this may be me.
3) The popover for viewing file content could be replaced with opening
a browser window (usually a tab).
4) Not as shiny as some web services.

Good:

1) It works!
2) Doesn't look horrible (i.e. bare HTML).
3) Keyboard navigation, keyboard shortcuts. Maybe add some more in
this regard? I find this is what I miss the most with web content.

that's why the response says "invalid user or password"... you can't tell which 
one is bad...

Make sure your computer can beep? (speaker connected, etc.)

Try "writeln(#07)"?

Check if X has beeps switched off ("xset -b")?

HTH anyhow,

Hello,

I've tried it on Debian Stretch, Firefox. Works great.
I could see the images, watch the video, upload a big
file and delete it. Nice tool.

Is there a Winows API I can call from my Lazarus program and get the same info ?

My aim is to detect which COM number was assigned to the USB device

Further, my understanding is that the loudspeaker is associated to the 
terminal in Linux. You can not thus beep from a daemon, something that 
would be useful. We apparently do not get access to program the chip as in 
MsDOS, nor freq,duration.


Here I post an attempt I did back on 2005. It doesn't compile, and this 
moment I can't check why. Nor, of course, do I remember what I was trying.

program beeper;

uses linux;

var
         Saved43, Saved61: byte;
         LoadClock: word;
         frequency: word;
         duration:  real;
         RequestedDuration, RemainingDuration: timespec;

         hh,mm,ss, msec, usec: word;
begin
(*
         if paramcount <> 2 then begin
                 writeln('Produces a beep of the indicated frequency and 
duration.');
                 writeln('Usage: beeper frequency duration');
                 halt(1);
         end;


         frequency:= round(ParamStr(1));
         duration:= ParamStr(2);
*)

         frequency:= 500;
         duration:=  1.2;


         RequestedDuration.tv_sec:=      trunc(duration);
         RequestedDuration.tv_nsec:=     trunc(frac(duration)*1e9);

         {ioperm(from, num, value)}
         writeln($61, '   ', $42);
         writeln(ioperm($61, 1, 1), ' ', ioperm($42, 2, 1));

                 {timer prepare}
         ReadPort($43, Saved43);
         writeln('43h', ' ', Saved43);
         writeport($43, byte($B6));      {Channel 2, LSB/MSB}

         LoadClock:= 1193180 div frequency;
         writeport($42, Lo(LoadClock));
         writeport($42, Hi(LoadClock));

         ReadPort($61, Saved61);
         writeln('61h', ' ', Saved61);
         writeport($61, byte(Saved61 or $3));    {Speaker on}


                 {Select(0, nil, nil, nil, 1000);}
         gettime(hh,mm,ss, msec, usec);
         writeln(hh,':', mm, ':', ss, '.', msec, ' ', usec);
         nanosleep(RequestedDuration, RemainingDuration);
         gettime(hh,mm,ss, msec, usec);
         writeln(hh,':', mm, ':', ss, '.', msec, ' ', usec);

         writeport($61, Saved61);        {Speaker off}

end.


I also have copies of some c code I got from fidonet posts that I can look 
at another day, in assembler. I don't remember if they worked, probably 
not.

Hello,

Attached unit will help you to implement a COM port browsing. There is a 
bit of extra code as original comes from a bigger unit, and this is an

Thanks Carlos!

I am presently recovering from surgery and taking medication for pain.  
I will try your suggestion once my pain is gone and I can think straight 
;-).

Open View->Debug Windows->Debug Output, is your -eval-command parameter
passed to gdb?

Hi Jose',

thank you for the code, but

1. I get a number of error messages while compiling the unit with
Lazarus 1.6.4 under W7 (see below)
2. I cannot understand how I can get the enumerated COM device names
into a TStringList as I need to process the names.

Thank you

Peppe

Hello,

I'm unable to understand how you get the first error :-? TLibHandle is 
in system unit which is mandatory, so I do not know how to you can get 
an "Identifier not found" :-?

Anyway, attached you can get a project sample, so you can process the 
data. You can extract the COM number from the name displayed.

Hi Jose',

doubting a configuration error, I uninstalled Lazarus, then installed
it again (current version is 1.8.2).

Unfortunately I could not get rid of the error on TLibHandle.

Then I found out that this type (TLibHandle) is not declared in
system.pas but in rtl/dynlibs.pas

http://i67.tinypic.com/20ft940.jpg

I fixed the problem by adding dynlibs.pas to the project.

Unfortunately when I compile the code I get new error messages (see
below) in unit lnfodwrf.

See

http://i68.tinypic.com/116qrdy.jpg

Well, I am sure I will fix all problems before or later :)

Thank you

Peppe

Is this written in Lazarus/FreePascal? If it is a single-bin program (CGI?)
i can drop somewhere in my VPS it would be awesome because i was trying to
make something like that a while ago (but got bored :-P).

It seems to work fine, but my only request is to allow for "untyped" URLs,
ie instead of /texts/, /images/, etc use /files/ or something generic so i
can - for example - upload an HTML file that refers to other files. For
example i uploaded foo.html that tries to refer to foo.png (which i also
uploaded) but it doesn't work:

https://storage.codebot.org/tester/texts/foo.html

This could be an option. Also for bonus credits, add an option to upload a
zip file and have it being decompressed in a (sub)directory.

Kostas,

It's written in C# and an ASP.NET application. It's easy enough to setup on
Windows, Linux, or even on a Raspberry Pi. The instance I linked originally
is actually running on an Amazon micro EC2 instance.

For those using Debian based Linux, getting ASP.NET running on Apache is as
simple as:

sudo apt install apache2 mono-complete libapache2-mod-mono
mono-apache-server4
sudo a2enmod mod_mono_auto
sudo service apache2 restart

After than you simply drop my project into your public /var/www/html/,
navigate to http://localhost, and everything will work.

I am adding a few more nice features like a graph of user activity for
administrators and some installation/usage guides to explain what the
project is and is not, and then I'll be posting the project plus all its
source to my gihhub account. Regarding enhancements, yes I am open to
anything, but I want get it published with features and documentation I
mentioned it first before I start adding more enhancements such as the ones
you were suggested (which were great btw).

And finally, to all about the source code and implementation:

This project is based on my existing C# library
<https://github.com/sysrpl/Codebot.Sharp> and Typescript library
<https://github.com/sysrpl/Codebot.Typescript> already on github. No
Webforms, no MVC, no Bootstrap, no jQuery, or other frameworks are used.

Here is the source code to the actual home page of the application:

Hello,

You have a somehow corrupted Lazarus/fpc installation. Ensure that your 
Lazarus configuration points to the right fpc executable, or start a 
configuration from scratch using the "--pcp" executable parameter. 
Something like "Lazarus.exe --pcp C:\Lazarus\CleanConfig"

TLibHandle is defined in "sysdlh.inc" which is included by "dynlibh.inc" 
which is included by "system" unit in Windows platform.

Also you get a compilation error in the dwarf support which has been 
included long time ago, so your Lazarus configuration is pointing to an 
old fpc 2.2 or something like that.
