Remarks

The OnCreateNodeClass event fires before a node is added to the control. It is raised when calling the Add method of the TTreeNodes class representing the control’s Items property. You can handle this event to specify the type of the that will represent the added node. The type must be a TTreeNode descendant.

The node class to be added must be assigned to the NodeClass parameter of the event.
