Package org.eclipse.jface.viewers
Interface ITreeSelection
- All Superinterfaces:
ISelection
,IStructuredSelection
,Iterable
- All Known Implementing Classes:
TreeSelection
A selection containing tree paths.
It is recommended that clients do not implement this interface but instead
use the standard implementation of this interface, TreeSelection
.
TreeSelection
adds API for getting the IElementComparer
of a selection (if available). This is important for clients who want to
create a slightly modified tree selection based on an existing tree
selection. The recommended coding pattern in this case is as follows:
ITreeSelection selection = (ITreeSelection)treeViewer.getSelection(); TreePath[] paths = selection.getPaths(); IElementComparer comparer = null; if (selection instanceof TreeSelection) { comparer = ((TreeSelection)selection).getElementComparer(); } TreePath[] modifiedPaths = ... // modify as required TreeSelection modifiedSelection = new TreeSelection(modifiedPaths, comparer);See bugs 135818 and 133375 for details.
