Method Gnome.Dialog()->run()

Method run

int run()

Description

Blocks until the user clicks a button or closes the dialog with the window manager's close decoration (or by pressing Escape).

You need to set up the dialog to do the right thing when a button is clicked or delete_event is received; you must consider both of those possibilities so that you know the status of the dialog when run() returns. A common mistake is to forget about Escape and the window manager close decoration; by default, these call close(), which by default destroys the dialog. If your button clicks do not destroy the dialog, you don't know whether the dialog is destroyed when run() returns. This is bad.

So you should either close the dialog on button clicks as well, or change the close() behavior to hide instead of destroy. You can do this with close_hides().
