Examples of org.eclipse.jface.viewers.CheckboxTreeViewer

org.eclipse.jface.viewers.CheckboxTreeViewer
A concrete tree-structured viewer based on an SWT Tree control with checkboxes on each node.
This class supports setting an {@link ICheckStateProvider} to set the checkbox states. To see standard SWT behavior, view SWT Snippet274.

This class is not intended to be subclassed outside the viewer framework. It is designed to be instantiated with a pre-existing SWT tree control and configured with a domain-specific content provider, label provider, element filter (optional), and element sorter (optional).
@noextend This class is not intended to be subclassed by clients.
