I need to make a component that descends from TTreeView. I want to add a button as subcomponent. constructor TMyTree.Create(AOwner: TComponent); begin inherited; bt := TButton.Create(Self) ; bt.Parent := Self ; btAll.SetSubComponent(True) ; btAll.Height := x ; etc, etc etc end; Everything works perfect, but when TTReeView Scroll, the button Scroll too. I would like to remain equidistant from the top edge. How should I deal with this problem? The Button Parent should be the same Parent of "Self" (i.e. the Form) ? I would thank you very much for a little clue to continue. I hope you understand my english. TIA
