Title: MDIChild no longer shows after installing 2.2.0
Post by: EganSolo on January 27, 2022, 01:16:06 am

I'm writing a MDI app. In the version of Lazarus prior to 2.2.0 (I forgot what that version was) the command MyForm.Show would be enough to show a form whose style is set to fsMDIChild.

In this version of Lazarus 2.2.0. this is not working: the form does not show. Please check the very simple test project I've attached. 

I checked the release page for this version and could not see any mention to MDI stuff. Am I missing something?

it looks as though form2 is outside bounds of form1
try setting its bounds to within form1 bounds ie

Code: Pascal  [Select][+][-]

1. If Not assigned(fChildForm)
2.   then begin
3.      fChildForm := TForm2.Create(Self);
4.      fChildForm.Parent := Self;
5.   end;
6.   If Not fChildForm.Visible
7.   then fChildForm.Show;
8.   fChildForm.SetBounds(10,10,400,300);

Created a bug report. Done.
Sigh
Reverting to previous version of Lazarus.
