You set the ColorMenu.Style to msOwnerDraw but then you don't implement the OnDrawItem and OnMeasureItem. So your menu items have a width of 0px and a height of 16px. And nothing is painted anyway because OnDrawItem is not assign. The "example form" creates its own style painter TJvXPColorMenuItemPainter and assigns it to ColorMenu.ItemPainter.


So this is not a bug but a handling error.


procedure TEditorMainForm.FormCreate(Sender: TObject);
  ColorMenu.ItemPainter := TJvXPColorMenuItemPainter.Create(Self);
  BackgroundMenu.ItemPainter := TJvXPColorMenuItemPainter.Create(Self);
