[ Version ( since = "4.2" ) ]
public void set_node_create_func (TreeManagerNodeFunc? func)

Sets the function to be called when a new node is being created by this.

If func is null then each created node will be a TreeNode object.

Specifying a custom TreeManagerNodeFunc function for example allows one to use specialized sub-classed TreeNode objects.

this	a TreeManager tree manager object
func	a TreeManagerNodeFunc function pointer, or null
