Question

I’ve got a GTK window with some widgets on it. There are a bunch of expanders on there, which all have the same activate signal handler. In this handler, I’d like to get the name of the widget object.

def exItem_activated (self, widget, data=None):
    for i in range (0, 15):
        self.builder.get_object ('exItem' + (str)(i + 1)).set_expanded (False)
    widget.expanded = True

    print widget.name

widget.name does not work, however; AttributeError: 'Expander' object has no attribute 'name'.
So basically, when expander2 is clicked, I want to get “expander2” as a string. When expander14 is clicked, I want to get “expander14” as a string. Is there any way to do this?

If this can’t (easily) be done, it would also be an acceptable if I could just get some other property by which I could tell which widget was clicked.

Answer 1

The corresponding method is called get_name() as far as I understand, eg.:

print expander.get_name()

Edit: for glade-based UI with gtk 2.20+ the gtk.Buildable.get_name() method should be used instead of gtk.Widget.get_name() since widget names are stored in id attribute of UI definition.
