Forms with the formstyle property set to fsStayOnTop only stay on top when they are the MainForm.

How do you make a non MainForm stay on Top?

Hi,
Please explain the case more. I just make a test, set form2 stay on top while form1 is the main form and form2 stays on top of form1. Do you want your any form to stay on top of other applications?

Igor,

Form1 is the mainform.
When form1 is hidden and form2 shown, form2 does not remain on top of other applications, regardless of the formstyle being set to fsStayOnTop.

Hi greenrc,

 Does this work? I've got it from somewhere but I don't know anymore from where...

 Form2.SetWindowPos(Handle,
                    HWND_TOPMOST,
                    Left,
                    Top,
                    Width,
                    Height,
                    SWP_NOACTIVATE or SWP_NOMOVE or SWP_NOSIZE);

 Try to put it in some events, like OnShow, ...

Zif.

Delphi 3 - Forms do not have a method 'SetWindowPos'

SetWindowPos is an API call, I think Zif meant pass it like so...

procedure TForm1.FormShow(Sender: TObject);
begin
 SetWindowPos(Handle,
                          HWND_TOPMOST,
                          Left,
                          Top,
                          Width,
                          Height,
                          SWP_NOACTIVATE or SWP_NOMOVE or SWP_NOSIZE);
end;

anyway try this and see if it works...(above)

Does not work for forms that are not the main form.

I don't think that it is a real bug - or an intended bug. I always use fsStayOnTop for secondary windows and want that they only stay on top of my main window - not on top of all other windows on the desktop.
Imagine floating toolbars, etc. They always have this behavior.
