hello shekou, you can set the amount of a control or form that you can see with a "Region". A region tells windows OS what part is allowed to be used (visible and gets mouse clicks). you can set the region in the Forms OnCreate event. This will make Panel1 Elipitcal - - - -


private
    { Private declarations }
    Rgn1 : HRGN;


procedure TForm1.FormCreate(Sender: TObject);
begin
Rgn1 := CreateEllipticRgn(Panel1.BoundsRect.Left-Panel1.Left, Panel1.BoundsRect.Top-Panel1.Top, Panel1.BoundsRect.Right-Panel1.Left, Panel1.BoundsRect.Bottom-Panel1.Top);
  SetWindowRgn(Panel1.Handle, Rgn1, TRUE);
end;


// be sure to Release the Region
procedure FormDestroy(Sender: TObject);
begin
DeleteObject(Rgn1);
end;


you can create Regions of many different shapes
