I assigned a png image in the backround of the smoothPanel and placed a smoothImageListBox as a child of the panel with the transparent property checked.
The listbox is placed on a portion of the panel(align alNone), and I would like to see only the items in the listbox with the portion of the image below by transparency.
Apparently the TSmoothImageListBox.transparent property applies to the background of the parent panel and not to its content..
