Method XbpTreeViewItem():setCaption() Foundation
Specifies a new caption.
ASSIGN METHOD :setCaption( <cCaption> ) --> lSuccess
This method returns .T. (true) if the caption could be updated, otherwise it returns .F. (false).
The method :setCaption() changes the caption for the XbpTreeViewItem object after the method :create() has been executed. The caption can be updated while the object is visible in the tree view.
This method is the ASSIGN method of the member variable :caption. It is called automatically whenever a value is assigned to :caption. Xbase++ applications need not call this method directly. Instead, the value contained in the :caption instance variable should be manipulated.
