gtk:dialog-set-response-sensitive (dialog response setting)

dialog -- a gtk:dialog widget
response -- a response ID, which is a positive integer or a value of the gtk:response-type enumeration
setting -- true for sensitive

Calls the gtk:widget-sensitive function for each widget in the action area of the dialog with the given response value. This is a convenient way to sensitize/desensitize dialog buttons. The gtk:dialog implementation is deprecated since 4.10. Use the gtk:window widget instead.
