how to properly destroy gtk.Dialog objects/widgets

Question

Noob @ programming with python and pygtk.

I'm creating an application which includes a couple of dialogs for user interaction.

#!usr/bin/env python
import gtk
info = gtk.MessageDialog(type=gtk.DIALOG_INFO, buttons=gtk.BUTTONS_OK)
info.set_property('title', 'Test info message')
info.set_property('text', 'Message to be displayed in the messagebox goes here')
if info.run() == gtk.RESPONSE_OK:
    info.destroy()

This displays my message dialog, however, when you click on the 'OK' button presented in the dialog, nothing happens, the box just freezes. What am I doing wrong here?

Answer 1

can you give me a last chance? ;)

there are some errors in your code:

• you did not close a bracket

• your syntax in .set_property is wrong: use: .set_property('property', 'value')

but i think they are copy/paste errors.

try this code, it works for me. maybe did you forget the gtk.main()?

import gtk

info = gtk.MessageDialog(buttons=gtk.BUTTONS_OK)
info.set_property('title', 'Test info message')
info.set_property('text', 'Message to be displayed in the messagebox goes here')
response = info.run()
if response == gtk.RESPONSE_OK:
    print 'ok'
else:
    print response
info.destroy()

gtk.main()

@mg My bad. Your code is correct (and I guess my initial code was too) The reason my dialog was remaining on the screen is because my gtk.main loop is running on a separate thread.

So all I had to was enclose your code (corrected version of mine) in between a

gtk.gdk.threads_enter()

and a

gtk.gdk.threads_leave()

and there it was. Thanks for your response.
