You can programmatically display a menu by using display-popup-menu (which is used internally to raise the context menu). The menu that display-popup-menu displays can be any properly constructed menu object, for example:
(defun popup-animal-menu (animal interface) (let* ((items (list (string-append "Get a picture of a " animal) (string-append "Send a postcard to " animal))) (menu (make-instance 'capi:menu :items items))) (capi:display-popup-menu menu :owner interface))) (capi:contain (make-instance 'capi:list-panel :items '("zebra" "dog" "parrot") :selection-callback 'popup-animal-menu))
Click on an item to see the menu.
You can use popup-menu-force-popdown to force a popup menu down (that is, make it disappear). This is useful for writing scripts that emulate user interactions.
