How can I create a GTK ComboBox with images in Pyt

问题:

How can I create a ComboBox that displays a list of entries, each containing some text and an icon?

I'm using Python and GTK3 with GObject introspection.

Here's an example of how to do that, inspired by this answer for C.

from gi.repository import Gtk
from gi.repository import GdkPixbuf

store = Gtk.ListStore(str, GdkPixbuf.Pixbuf)

pb = GdkPixbuf.Pixbuf.new_from_file_at_size("picture.png", 32, 32)
store.append(["Test", pb])

combo = Gtk.ComboBox.new_with_model(store)

renderer = Gtk.CellRendererText()
combo.pack_start(renderer, True)
combo.add_attribute(renderer, "text", 0)

renderer = Gtk.CellRendererPixbuf()
combo.pack_start(renderer, False)
combo.add_attribute(renderer, "pixbuf", 1)

window = Gtk.Window()
window.add(combo)
window.show_all()

window.connect('delete-event', lambda w, e: Gtk.main_quit())

Gtk.main()

The same example in GTK2, inspired by your code:

import pygtk
pygtk.require('2.0')
import gtk
import gtk.gdk
import gobject
import gc

store = gtk.ListStore(str, gtk.gdk.Pixbuf) 

pb = gtk.gdk.pixbuf_new_from_file("picture.png")
store.append(["Test", pb])

combo = gtk.ComboBox(store)

renderer = gtk.CellRendererText()
combo.pack_start(renderer, True)
combo.add_attribute(renderer, "text", 0)

renderer = gtk.CellRendererPixbuf()
combo.pack_start(renderer, False)
combo.add_attribute(renderer, "pixbuf", 1)

window = gtk.Window(gtk.WINDOW_TOPLEVEL)
window.add(combo)
window.show_all()

window.connect('delete-event', lambda w, e: gtk.main_quit())

gtk.main()
