Form AlphaBlending is supported on Windows/Linux/Mac, but when I set form parent to another form, alphablending is lost on Linux and Mac.
So my question is: It's widgeset problem (missing implementation) or platform support(Linux and MacOS)?
eg.: (working only on windows as expected)
var
frm: TForm2;
begin
frm := TForm2.Create(Application);
frm.BorderStyle:=bsnone;
frm.Align:= alClient;
frm.AlphaBlend:=true;
frm.AlphaBlendValue:= 200;
frm.Parent := Panel1;
frm.Show;
end;
