[lazarus] Question about component structure

[Baeseman, Cliff]

Well I need to draw up what we need here but this is the way it needs to go.


1. I have to implement the anchors concept in the controls that are supposed
to have them.

2. I have to implement the align property in controls that are supposed to
have them.

3. Only certain types of controls, containers are allowed to contain
widgets. This means that I will have to implement some type of logic to
determine when and to what controls to  apply the fixed widget.

   something like in the control load a fixed widget if one does not yet
exist and the parent control is a container type widget.


4. The properties for the heigth width top and left are somehow getting
hosed. I have not tracked the source of that one as of yet. This should go
away once I redo all of that stuff.

5. a control without a anchor set or an align set should not fire a resize
event or have one fired for it. For instance a button does not have a
published resize event. It does in the existing implementation but it should
not for delphi compatibility reasons.

Cliff,

You might take a look at the Notebook component that I created. It is
interesting because the alignment problem exists with the notebook component
on
a form, but it doesn't exist with a button on a page. I can put a button
anywhere on the notebook page and it works fine. But the notebook component
seems to want to align itself on a form in the upper left hand corner and I
can't move it. So I don't know what the difference is between the way the
normal alignment code works and the alignment code for the TPage control
that
the notebook is using. But there is something different. Might be somewhat
helpful.

BTW, I won't get any coding done this weekend. I am going camping with my
family. But I will finish moving the gtk code to the gtkint units Sunday or
Monday evening and commit it.
