Property
GtkAlertDialog:cancel-button
since: 4.10
Description [src]
This property determines what happens when the Escape key is pressed while the alert is shown.
If this property holds the index of a button in GtkAlertDialog:buttons,
then pressing Escape is treated as if that button was pressed. If it is -1
or not a valid index for the buttons array, then an error is returned.
If buttons is NULL, then the automatically created ‘Close’ button
is treated as both cancel and default button, so 0 is returned.
