Answer 1

Here is what worked for me:

class CellRendererClickablePixbuf(gtk.CellRendererPixbuf):
    gsignal('clicked', str)
    def __init__(self):
        gtk.CellRendererPixbuf.__init__(self)
        self.set_property('mode', gtk.CELL_RENDERER_MODE_ACTIVATABLE)
    def do_activate(self, event, widget, path, background_area, cell_area, flags):
        self.emit('clicked', path)
