Method XbpStatusBar():numItems() Foundation
Returns the number of status bar items (panels) defined for an XbpStatusBar object.
:numItems() => nItems
:numItems() returns a numeric value with the number of panels currently defined for the XbpStatusBar object executing the method.
After an XbpStatusBar object is created, the method :numItems() can be used to determine the number of status bar panels defined. The item count increases each time a new item is added using :addItem(), and decreases each time :delItem() is called.
