MousePos Screen

Is there a function in TMS WebCore with which I get the absolute mouse position on the screen.
It looks like this in Delphi:

procedure TForm1.Timer1Timer(Sender: TObject);
  mousePos : TPOINT;
  Label1.Caption := IntToStr(mousePos.X) + ' / ' + IntToStr(mousePos.Y);

I need the absolute change of the mouse position in the Y direction, even if the mouse is dragged outside of the active web form

Sorry, there is at this moment no such call.
There is no such call directly in the browser API. You'd need to track the position from the OnMouseMove, for example from the form.
