Differentiate gtk.Entry icons

I'm adding two icons to a gtk.Entry in PyGTK. The icons signals are handled by the following method

def entry_icon_event(self, widget, position, event)

I'm trying to differentiate between the two of them:

<enum GTK_ENTRY_ICON_PRIMARY of type GtkEntryIconPosition>
<enum GTK_ENTRY_ICON_SECONDARY of type GtkEntryIconPosition>

How can I do this? I've been digging through the documentation of PyGTK but there's n开发者_如何学Pythono object GtkEntryIconPosition nor any definition for this enums.

Thanks

Alright, since no one gave an answer, I'll do with what I actually found. A method to use this icons would look like this:

def entry_icon_event(self, widget, icon, event):
    if icon.value_name == "GTK_ENTRY_ICON_PRIMARY":
        print "First Button"
        if event.button == 0:
            print "Left Click":
        else:
            print "Right Click"
    elif icon.value_name == "GTK_ENTRY_ICON_SECONDARY":
        print "Second Button"
        if event.button == 0:
            print "Left Click":
        else:
            print "Right Click"

There is better way to do it:

def entry_icon_event(self, widget, icon, event):
    if icon == gtk.ENTRY_ICON_PRIMARY:
        ...
    elif icon == gtk.ENTRY_ICON_SECONDARY:
        ...
