It took me a while to find this, so I'm just blogging it so other people will be able to find it.
With the following snippet, I managed to do it.
import pynotify pynotify.init("myapp") import gtk n = pynotify.Notification(summary="Summary", message="Message!") n.set_icon_from_pixbuf(gtk.Label().render_icon(gtk.STOCK_HARDDISK, gtk.ICON_SIZE_LARGE_TOOLBAR)) n.show()
Note that the use of a Label is just to have a widget instanciated to use the render_icon() method. It could be any widget type as far as I understand.
