[pygtk] (FileChooserDialog) Save-Overwrite

[Andrea Caminiti]

hi:

i'm having some troubles trying to figure out how to use the overwrite option.
right now i have a save button that is connected the click button signal to 
def save_file. but feel that i'm doing somethingwrong with the overwrite function.
this is the code i'm using.

    def save_file(self):
        global file
        dialog = gtk.FileChooserDialog("Save..",
                                       None,
                                       gtk.FILE_CHOOSER_ACTION_SAVE,
                                       (gtk.STOCK_CANCEL, gtk.RESPONSE_CANCEL,
                                       gtk.STOCK_SAVE, gtk.RESPONSE_OK))
        dialog.set_default_response(gtk.RESPONSE_OK)

        filter = gtk.FileFilter()
        filter.set_name("All files")
        filter.add_pattern("*")

        dialog.add_filter(filter)
        dialog.show()
        response = dialog.run()
        if response == gtk.RESPONSE_OK:
            name = dialog.get_filename()
            if file == None and file != name:
                file = open(dialog.get_filename(), 'w')
                print file
            elif file != None and name == file:
                dialog.set_do_overwrite_confirmation(True)
                dialog.connect("confirm-overwrite", self.confirm_overwrite_callback)
                file = open(dialog.get_filename(), 'w')
                print file
            file.write("something")
            dialog.destroy()
        elif response == gtk.RESPONSE_CANCEL:
            pass
        dialog.destroy()
        return    

    def confirm_overwrite_callback(self, widget):
        uri = gtk.FileChooserDialog.get_filename()
        if is_uri_read_only(uri):
            if user_wants_to_replace_read_only_file (uri):
                return gtk.FILE_CHOOSER_CONFIRMATION_ACCEPT_FILENAME
            else:
                return gtk.FILE_CHOOSER_CONFIRMATION_SELECT_AGAIN
        else:
    # fall back to the default dialog
            return gtk.FILE_CHOOSER_CONFIRMATION_CONFIRM 
        return

when i try it, an select an existing file, no overwrite dialog was displayed. when i check 
the file the previous content was changed for the new one. any idea on what's wrong? 
any suggestions?
