Question

Quite a simple one i would think, but i need to be able to Maximize a form to a particular screen. Cant seem to find any Delphi specific info.

I can remember the forms position over subsequent application loads. However, when i restore the position, then call WindowState := wsMaximized, the form moves to the other screen! (i do have other forms also visible on that screen – it appears its maximizing to the ‘active screen’)

So i need a function like so:

procedure Maximize(const aScreenIndex : Integer);
begin
 if aScreenIndex < Screen.MonitorCount then
   //Maximize to that screen
end;

Answer 1

Intercept the WM_GETMINMAXINFO message and adjust the coordinates inside its MINMAXINFO structure as needed.
