Hello,

have some trouble with Form.ShowModal...

Form1:= TForm1.create;
Form1.ShowModal;

Should bring Form1 to front, keep it on top of all other project forms and stay there until it is closed. Is this right?

But sometimes when I click on the Mainform behind Form1 Mainform comes to front and Form1 is hidden behind it.... I am using GTK2 widgetset from svn.

Am I doing something wrong calling ShowModal? Or is it a bug?

regards,
sebastian

Under Linux, Modal forms and "stay on top" are simply requests to the window manager. Not all windows managers are equal, and will not always act on your request.

You will find that in the case of Modal forms, you might be able to click and bring focus to other non-modal forms, but you shouldn't be able change anything in those forms.

What Window Manager are you using?

I'm using Kubuntu with KDE 3.5.10. No compiz. Any known issues with this?

exactly... all other forms are disabled. So if I loose focus on my modal form it is quite difficult to bring it back because the modal form is not in taskbar...

That recalls me similar bug under Windows (I suspect it is regression because long time ago when I coded OnMinimize/OnMaximize events it was working well) - if you show modally dialog or form and close it focus is not returned to previous one (even if it's main form), so working using keyboard is very difficult now.

Then it must be a bug in the toolkit (LCL or even GTK2). For example in fpGUI - You can set focus to other non-modal forms and move them (but no editing), while a modal form is showing, but the modal form is always above it's Parent form. If you click on the parent form, the model form will appear above it. So you don't have the issue of not "finding" the modal form again.

Ok... I will create a bug report.

any ideas for a fast workaround? The problem with the modal form getting lost behind other forms occurs most times only on the first ShowModal every program run.

I suppose the dialogs are not created on-the-fly... Hmmm... the most ugly workaround I can think of:

1. Put a timer on any form that is to be shown Modal
2. Start the timer in the onshow-event IF a flag is set.
    When the timer fires, close the form.
3. Call all your dialogs when the main-program starts:
    with thedialog do
     begin
      SetTheFlag;
      ShowModal;
     end;

Should work if things happen only at the first Showmodal. Now every form has had its first showmodal.

Speaking of workarounds.... ;-)

goodluck!

I found out that it is the same problem with dialogs that are created using ShowMessage(); They also get hidden behind the main form.

Have created a bug report this morning.
