[Lazarus] Rebuilding IDE Gtk/Qt

[Vojtěch Čihák]

I found the reason but to make a patch is beyond my powers.
When I used the steps described below, I got this in console:

See several "Hint: (lazarus) [TBuildManager.SetBuildTarget]..." about changing widgetset.Lines "HEREx lpQt" are from me, they indicates that state of MiscellaneousOptions.BuildLazProfiles.Current.TargetPlatform); is unchangedThe changes come from method MainBuildBoss.SetBuildTargetProject1 which is called several times in main.pp, mainly in TMainIDE.mnuToolConfigBuildLazClicked at line 4595.It calls TBuildManager.SetBuildTarget and nested function GetEffectiveLCLWidgetType where is line: Result:=FBuildTarget.CompilerOptions.GetEffectiveLCLWidgetTypeIt is probably the reason why combobox in "Configure Build Lazarus" is ignored and is replaced by value from Compiler Options.V.______________________________________________________________

Thanks to zeljko for confirming.
 
I was able to reproduce right now:
 
I have my Lazarus 1.9.0 r56925M FPC 3.0.4 x86_64-linux-qt.
I started new project. I saved it. I open Project Options -> Addition and Overrides and added LCLWidgetType "gtk2".
I run the project once just to see it is really GTk2 - it is.
Now I enter Tools -> Configure Bulid Lazarus. Options are Debug IDE, LCL WIdgetType = qt. I don't change them.
I switch to "Clean common files" and click Build.
After restart I have Lazarus 1.9.0 r56925M FPC 3.0.4 x86_64-linux-gtk2.
