Pygtk : Destroying Combobox Causes Error

My aim is to destroy a combobox if one of its items is active. I wrote this test code : import pygtk pygtk.require('2.0') import gtk import gobject def remove(combobox): if 'Opt

Solution 1:

It comes because you use a liststore. New gtk code should now use combo_box_new_text()

here is your code working :

for i in range(nb):
  combo = gtk.combo_box_new_text()
  cell = gtk.CellRendererText()
  combo.pack_start(cell, True)
  combo.add_attribute(cell, 'text', 0)
  for 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() 

Solution 2:

Your code is solid, the widgets are destroyed like they should be. Just write it off as an oddity of pygtk/PyGObject's memory management.

Solution 3:

So why are you not using

combobox.hide()

instead of

combobox.destroy()

It seems destroying individual widgets is not really the thing you should do. In most cases I do not destroy Gtk widgets, since later you may wish to show them again.
