gtk:notebook-action-widget (notebook packtype)

notebook -- a gtk:notebook widget
packtype -- a gtk:pack-type value for the action
widget -- a gtk:widget object

The gtk:notebook-action-widget function gets one of the action widgets. The (setf gtk:notebook-action-widget) function sets the widget as one of the action widgets. Depending on the pack type the widget will be placed before or after the notebook tabs. You can use a gtk:box widget if you need to pack more than one widget on the same side.
