Form out of screen
lazarus / 32-Linux

Hi everybody!

I'm trying to design - on runtime - a form out of screen, making it
appear slowly inside it.
Using Screen properties I get correct values, nevertheless form
doesn't start from outside, but directly from the extreme screen
positions near my coordinates.

Under win i can manage to get desired result (using specific
functions), under linux (kubuntu 11.04) not yet.
Anybody knows how to?

Thanks

This is a feature in KDE's window manager, not in Lazarus.
There may be a setting for it but I am not sure.

Works. (Linux + Qt , KDE4)
Code: [Select]procedure TForm1.FormActivate(Sender: TObject);
begin
  Left:=1680;
  OnActivate:=nil;
end;

procedure TForm1.Timer1Timer(Sender: TObject);
begin
  if Left>600 then Left:=Left-4
    else Timer1.Enabled:=False;
end;
Set Timer interval = 50 (ms).

@ JuhaManninen
I see, thanks

@ Blaazen
Doesn't work: I used in my code left and top properties to adjust
starting position. Checked yours with same result too. Thanks anyway

A friend of mine suggested me a simple idea: just set form's height to
0 and get it up step by step.

Have you tried to use setbounds? and i think you need to show the form
before you can move it from original position to out of screen.

Not setbounds directly, but top property has been used after form
showed; to be sure i tried with a new form project, a button on,
clickbutton event which i set form's position in. Nothing to do.
