Examples of org.eclipse.jface.viewers.TreePath

org.eclipse.jface.viewers.TreePath
A tree path denotes a model element in a tree viewer. Tree path objects have value semantics. A model element is represented by a path of elements in the tree from the root element to the leaf element.
Clients may instantiate this class. Not intended to be subclassed.
