Talk:Application full screen mode

From Free Pascal wiki

I think of : [code] procedure TForm1.ToggleFullScreen;

 function IsFullScreen: boolean;
 var
   CheckScreenBounds: TRect;
 begin
   CheckScreenBounds := Screen.MonitorFromWindow(Handle).BoundsRect;
   Result := ((CheckScreenBounds.Top = Form1.BoundsRect.Top) and
     (CheckScreenBounds.Left = Form1.BoundsRect.Left) and
     (CheckScreenBounds.Bottom = Form1.BoundsRect.Bottom) and
     (CheckScreenBounds.Right = Form1.BoundsRect.Right));
 end;

begin

 if not IsFullScreen then 
 begin
   // To full screen
   OriginalWindowState := WindowState;
   OriginalBounds := BoundsRect;
   //BorderStyle := bsNone;
   ScreenBounds := Screen.MonitorFromWindow(Handle).BoundsRect;
   with ScreenBounds do
     SetBounds(Left, Top, Right - Left, Bottom - Top);
 end
 else
 begin
   if OriginalWindowState = wsMaximized then
     WindowState := wsMaximized
   else
     with OriginalBounds do
       SetBounds(Left, Top, Right - Left, Bottom - Top);
 end;

end; [/code]

This lets the design-time decision of BorderStyle be honoured when coming back from full screen, by not treating the BorderStyle variable as form state variable.
