python 2.7 - PyGtk : destroying combobox causes error -

-

my aim destroy combobox if 1 of items active.

i wrote test code :

import pygtk pygtk.require('2.0') import gtk import gobject  def remove(combobox):   if 'optionc' in combobox.get_active_text():     combobox.destroy()  window = gtk.window(gtk.window_toplevel) window.set_default_size(800, 600) window.set_title("test") window.connect("destroy", gtk.main_quit) main_box = gtk.vbox(false, 2) window.add(main_box) nb = 3 in range(nb):   liststore = gtk.liststore(gobject.type_string)   combo = gtk.combobox(liststore)   cell = gtk.cellrenderertext()   combo.pack_start(cell, true)   combo.add_attribute(cell, 'text', 0)   text in ["optiona-%d"%(i+1), "optionb-%d"%(i+1), "optionc-%d"%(i+1)]:     combo.append_text(text)     combo.set_active(0)   combo.connect("changed", remove)   main_box.pack_start(combo, expand=false) window.show_all() gtk.main()

if open popup of combobox , click select "optionc", have message :

combo.py:29: warning: invalid unclassed pointer in cast `gobject' gtk.main() combo.py:29: warning: g_object_notify: assertion `g_is_object (object)' failed gtk.main() combo.py:29: warning: g_object_set: assertion `g_is_object (object)' failed gtk.main()

but if select "optionc" scolling combobox (without opening popup), no error encountered.

thanks advice!

answer : (working pygtk version 2.24 not 2.16)

replace block :

liststore = gtk.liststore(gobject.type_string) combo = gtk.combobox(liststore) cell = gtk.cellrenderertext() combo.pack_start(cell, true) combo.add_attribute(cell, 'text', 0)

by function :

combo = gtk.combo_box_new_text()

it comes because use liststore. new gtk code should use combo_box_new_text()

here code working :

for in range(nb):   combo = gtk.combo_box_new_text()   cell = gtk.cellrenderertext()   combo.pack_start(cell, true)   combo.add_attribute(cell, 'text', 0)   text in ["optiona-%d"%(i+1), "optionb-%d"%(i+1), "optionc-%d"%(i+1)]:     combo.append_text(text)     combo.set_active(0)   combo.connect("changed", remove)   main_box.pack_start(combo, expand=false) window.show_all() gtk.main()
