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

复制代码 代码如下:

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;
