How do I show multiple times a dialog defined with Glade?

I would like to show a Gtk.Dialog defined in a Glade file multiple times.

Currently I am able to do it using a custom button to call the hide() method of the Dialog but, if the user uses Alt+F4 to close the dialog, it re-opens empty:

enter image description here

And in console I see multiple errors:

I am getting the instance of the Dialog with a normal get_object():

 self.__settings_dialog : Gtk.Dialog = self.__builder.get_object("settings_dialog")

and than just calling show() and hide(). But after closing it with Alt+F4 I am not able to show it again.

Thanks to a Reddit user, I find out that you have to connect to the dialog's delete-event and make sure to return True to avoid the dialog being destroyed.

First create the signal handler in Glade, then in your Python code:

def on_dialog_delete_event(self, dialog, event):
    dialog.hide()
    return True
