Question

I create a Dialog, and at some point I need to toggle sensitive flag of OK button (gtk.STOCK_OK). I successfully access action_area and buttons in it, but how do I identify the OK button?
Also, is there a simpler way to enable/disable OK button?

Thanks.

Using the label should work, but it’s very fragile; translations will probably break it, and your positive-response buttons won’t always be called “OK” anyway. You should consider using the response ID to identify the appropriate button instead. For example, a typical OK button might be created using:

dialog.add_button(gtk.STOCK_OK, gtk.RESPONSE_OK)

You can then retrieve your OK button later using the get_widget_for_response call, which seems perfectly designed to do exactly what you want to do:

dialog.get_widget_for_response(gtk.RESPONSE_OK)

I’d suggest that this is probably the way you should do it; it’s similar to the way that the set_alternative_button_order() API works, which suggests that it’s what was intended.
