trzGroupBar Scrolling with Mouse wheel

I need to scroll the items in a rzGroupBar with the mouse wheel. How do I enable scrolling with the wheel?

The TRzGroupBar does handle the mouse wheel when a group in the group bar has the focus. However, by default, clicking on a TRzGroupItem item in a group does not focus the group. This is similar behavior to a tool button on a toolbar (i.e. no focus change). However, if you click on the caption of a TRzGroup (to collapse or expand the group), the focus does change. Then the mouse wheel will work. In the OnClick event handlers for the items, you could change the focus to the group so that each time an item was clicked, the focus would change to the group and the mouse wheel would work. For example,

Code: Select all
procedure TForm1.RzGroup1Items0Click(Sender: TObject);
