FileChooserDialog in pygtk

Question

The question is simple: i just want to open my FileChooserDialog many times as i want, without re-creating the same widget.

Destroy signal/method is not for me, because i don't want to destroy the reference to the object, i just need to hide the FileChooserDialog

The problem is that, by this code, i just get the dialog with the the buttons, but nothing else (no paths, no files list, no folders..) just the buttons and a grey blank window.

HERE BELOW THE CODE:

self.__file_chooser_dialog = gtk.FileChooserDialog("Open..",
                                        None,
                                        gtk.FILE_CHOOSER_ACTION_OPEN,
                                        (gtk.STOCK_CANCEL, gtk.RESPONSE_CANCEL,
                                        gtk.STOCK_OPEN, gtk.RESPONSE_OK))

def file_chooser_event(self, widget, data=None):
        self.__file_chooser_dialog.show_all()
        response = self.__file_chooser_dialog.run()
        if response == gtk.RESPONSE_OK:
            print self.__file_chooser_dialog.get_filename(), 'selected'
        elif response == gtk.RESPONSE_CANCEL:
            print 'Closed, no files selected'

        self.__file_chooser_dialog.hide_all()


self.__load_config=gtk.Button('Carica file di configurazione\n(nome__file.ini)')
self.__load_config.connect('clicked', self.file_chooser_event)

Answer 1

You should consider using gtk.Widget::hide_on_delete, which exists for that purpose.

Answer 2

i've tried multiple ways to let it work.. and you just need to do this edit:

self.__file_chooser_dialog.show_all() -----> self.__file_chooser_dialog.show()

self.__file_chooser_dialog.hide_all() -----> self.__file_chooser_dialog.hide()

Can you explain me why this works?!
