[pygtk] emulate Live Bookmarks buttons?

[Karl Ostmo]

Hello,
I am trying to create a button the behaves and looks like the "Live
Bookmark" or "Smart Bookmarks" buttons in the Bookmarks Toolbar in Firefox
3.  E.g. - I would like it to have an icon, text, and a downward-pointing
gtk.Arrow on the right side, and the button should stay depressed while the
popup menu is open.

I would actually prefer for this button to be part of a gtk.Toolbar, such as
a gtk.ToolButton.  However, gtk.MenuToolButton does not do what I want; that
widget has the menu part split into a separate button, as in the "Recent
pages" next to the Forward and Back buttons in Firefox 3 (Linux version).

Trying to pack a gtk.Arrow into a gtk.Button gives unexpected results; the
arrow always ends up between the label and the icon, even after applying
"reorder_child(...)".  I am also not sure how to attach the menu to a button
such that the button stays depressed while the menu is up.  My code for the
unsuccessful attempts is below.  Suggestions would be much appreciated!

Karl
