Description
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.
