That works, thanks...

Now I can't seem to make out what to do in order to Make Menu.Popup()
work. I try to do this:

System.IntPtr data = new System.IntPtr();
treeViewMenu.Popup(null. null, new Gtk.MenuPositionFunc(PosFunc), data,
0, 1);

But it only return without anything happening, I guess that the two
first parameters are optional, and since I'm doing a popup I don't need
those, The next is somewhat uncertain, But according to the source it is
a Delegate. The two next puzzels me! The last I found in a doc
somewhere, it's supposed to popdown the menu when I release the mouse
button. Can anyone explain these parameters for me?
