Python Gtk3，MessageDialog，隐藏对话框后的默认焦点响应？

Question

after destroying dialog we can create new one with default focused response using set_default_response method. but when we hide dialog instead of destroying, this method does not work. how can I do this ?

example

#dialog variable is a GtkMessage dialog.
dialog.run()
dialog.hide()
dialog.run() # default focus doesn't work when we run dialog again after hiding.

Thanks.

This does not happen because the dialog widget will keep its state. This is the expected behavior. If you destroy and create a new one, it will be initialized.
