Hi Tim

I tried a simple runtime creation of a panel, but nothing shows:

procedure TForm1.Button3Click(Sender: TObject);
begin
  FTestPanel := TPanel.Create(self);
  FTestPanel.Visible := true;
  FTestPanel.EnableDrag := true;
  FTestPanel.Caption := 'TestPanel';
  FTestPanel.ShowBorder := true;
  FTestPanel.ShowCaption := true;
  FTestPanel.Show;
end;

Is this a bug or am I missing something?

Cheers, Bob

Bob,

Set the size as well :
 FTestPanel.Top := 100;
 FTestPanel.left := 100;
 FTestPanel.Width := 100;
 FTestPanel.Height := 100;

and it should show up (without need to call Show)

Hmm, interesting question - should the size default to some value, or is the
current situation reasonable ?

My vote would be to have controls with a default non zero height and width size at 0,0

Otherwise i can see this being reported a bug/issue all the time once we start creating them run-time

Yep, that's what I was thinking also, and it's what Delphi does.

Thanks Raul - unbelievable, I think I set just about every other
property apart from those! I think you're right - without default values
it'll be reported as a bug again.

Cheers, Bob
