uniScreenmask for MainForm

[erich.wanker]

Hello,

 

i have a mainform and i want to mask the hole form:

 

i set at designtime: Mainform.screenMask.Target = MainForm

 

and at runtime i have:

procedure TMainForm.UniImage7MouseEnter(Sender: TObject);
begin
mainform.ScreenMask.Enabled:=true;
uniform4.Show;...

 

but the Mainform didn´t get a mask - and ideas ?
