AlertDialogGidBuilderImpl.cancelButton

T cancelButton(int propval)

Set cancelButton property.

Parameters

propval 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 [gtk.alert_dialog.AlertDialog.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.

Returns

Builder instance for fluent chaining
