Method XbpToolBar():getItem() Foundation
Retrieves an item (button) from the XbpToolBar object's item array.
:getItem( <nItem> | <cItemKey ) => oButton
The method :getItem() returns a XbpToolBarButton object.
The method :getItem() can be used by an Xbase++ application to retrieve a reference to one of the tool bar buttons defined. The reference can be used to modify the tool bar button's properties. This allows to assign a new caption string at run time or to modify the image displayed by a toolbar button object.
The item to be retrieved may be specified using either its ordinal position or key. Addressing the item via it's unique key string is actually recommended for better source code readability and easier code maintenance.
