delphi 程序全屏显示无标题栏,覆盖整个屏幕

delphi 程序全屏显示无标题栏,覆盖整个屏幕,这个在做工控机或屏保时有用的,所以记下

 

procedure TMainFrm.FormCreate(Sender: TObject);

begin

with MainFrm do begin

{ Position form }
Top := 0 ;
Left := 0 ;
{ Go full screen}
BorderStyle := bsNone ;
WindowState  := wsmaximized;
ClientWidth  := Screen.Width ;
ClientHeight := Screen.Height;
Refresh;
SetForegroundWindow(Handle) ;
SetActiveWindow(Application.Handle) ;

end;

end;
