DoAddItem is a procedure used to perform actions needed when a new tree node is added to the shell control. DoAddItem signals the OnAddItem event handler (when assigned) to examine and process the arguments passed to the method.
ABasePath contains the path on the local file system where the file system object exists.
AFileInfo is a TSearchRec instance with the details for the file system object.
CanAdd is a variable Boolean parameter used to indicate if the new tree node can be added to the shell control.
No actions are performed in the method when OnAddItem has not been assigned (contains Nil). Applications must implement and assign an object procedure to the event handler which responds to the event notification.
