how to click "close window" don't close GTK window?

[holmes86]

hi,everyone

I have a GTK window,when click "close window" ,I want to show a verify dialog that whether verify really quit or not.so I used a MesssageDialog for verify quit.But when I clicked the "NO" button on the verify dialog,the GTK window also closed.

The GTK window I make for glade,and I set the signal are "delete_event","close" and "response" all don't doing it.

any help will be appreciate.

Well, I guess you're attaching a callback function to the 'delete-event' singal, correct? Well, depending on the response from the dialog window, your callback should return either TRUE (continue with delete event), or FALSE (cancel delete event). This is what I remember from my brief work with it using PHP-Gtk.

thanks Markus,my code is as following:

def show_verify_dialog(self,str):
    verdialog = gtk.MessageDialog(type=gtk.MESSAGE_QUESTION,buttons=gtk.BUTTONS_YES_NO,message_format=str)
    verd = verdialog.run()
    verdialog.destroy()
    if verd == gtk.RESPONSE_YES:
        return True
    else:
        return False
 
    def gtk_widget_destroy(self,window,event=None):
        mesg = 'Would you like to quit TLait?'
        if show_verify_dialog(self,mesg):
            gtk.main_quit()
        else:
            return
 

Meanwhile,I set the signal is "delete_event",but the problem is as same
