Method XbpToolBarButton():numItems() Foundation

Returns the number of menu items defined in a tool bar (button's) drop-down menu.

:numItems() => nItems

:numItems() returns a numeric value with the number of menu items currently defined in the drop-down menu of the XbpToolBarButton object executing the method.


After a tool bar button is added to a tool bar object, the method :numItems() can be used to determine the number menu items defined for the button's drop-down menu. The item count increases each time a new menu item is added using:addItem(), and decreases each time :delItem() is called.

Drop-menus are only supported for tool bar button objects that have the XBPTOOLBAR_BUTTON_DROPDOWN style. See the instance variable :style for further information.
