Cannot get location/size

[FireZura]

Hi. I'm trying to get the location/size (tried before and after opening tabtip) with
System.Drawing.Rectangle clavier = TabTip.GetTabTipRectangle(); Console.WriteLine(clavier.Location); Console.WriteLine(clavier.Size);

but i get
{X=0,Y=0} {Width=1, Height=1}

Any idea how to get the correct values ?
