Just making sure that I did not miss something crucial.

No problem, thanks for pointing them, these are good improvements.

Engkin's code with some modifications works very good on windows:
Code: Pascal  [Select]
  1. procedure TForm1.Button1Click(Sender: TObject);
  2. var
  3.   f:TForm;
  4. begin
  5.   f:=TForm.Create(self);
  6.   f.ShowInTaskBar:=stNever;
  7.   f.BorderStyle:=bsNone;
  8.   f.BoundsRect := Rect(0,0,ClientWidth, ClientHeight);
  9.   f.AlphaBlend:=True;
  10.   f.AlphaBlendValue:=120;
  11.   f.Color:=clBlack;
  12.   f.Parent:=self;
  13.   f.Show;
  14.  
  15.   MessageDlg('Hello, this is modal dialog.', mtInformation, [mbOK],0);
  16.  
  17.   f.Free;
  18. end;
  19.  

Maybe it works on linux (with enabled compositor) and macos too.

Hm, the next challenge could be not to just darkening the background, but to "blur" it, so that you e.g. cannot read the background form any more... ;-)

With the example I submitted just apply blur with BGRABitmap and that's all.
