As far as I know it is not possible... however you could create a gui with $WS_POPUPWINDOW and use WinSetTrans() on the whole gui...example thrown together quick and dirty from help-file...

If that doesnt suite your purpose, maybe search the forum for embedding a window in a gui and mix up two windows...

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <TreeViewConstants.au3>
#include <StaticConstants.au3>

you can set the whole control's transparency but not the background only ?

you could create your own treeview made of labels though... although it should be a quite small one

cheers
