TVirtualDrawTree.OnLoadNode Event

Streaming support event.

property OnLoadNode: TVTSaveNodeEvent;

This event is typically triggered when serialized tree data must be restored, e.g. when loading the tree from file or stream or during a clipboard/drag'n drop operation. You should only read in what you wrote out in OnSaveNode. For safety there is a check in the loader code which tries to keep the internal serialization structure intact in case the application does not read correctly.
