Méthode	Description
DeselectChildren ( ITreeNode parent ) : int	Deselects all children of the given node.
FirstDescendent ( ITreeNode parent, FuncBool predicate ) : ITreeNode	Gets the first descendent node that matches the given predicate.
FirstRemainingParent ( ITreeNode root, ITreeNode orphan ) : ITreeNode	Retrieves the first ancestor of a node that still exists as a descendent of the root node. Useful for when a node is removed, and you want to move a view to the reamining parent.
FirstSelectedChild ( ITreeNode parent ) : ITreeNode	Retrieves the first selected child node.
HasSelectedChild ( ITreeNode parent ) : bool	Determines whether at least one of the children of the given node are selected.

Deselects all children of the given node.
