public class CheckableTreeViewer
extends CheckboxTreeViewer

Checkable tree viewer implementation, based on CheckboxTreeViewer. Since CheckboxTreeViewer does not allow to hide some checkboxes, there is a need in such tree viewer. All data that is stored in tree viewer is represented by custom tree structure CheckableTreeItem. This editor uses lazy loading, so elements are loaded only when user expands node from tree. Checked elements are set only when some tree node is expanding.
