public class ContainerCheckedTreeViewer

extends CheckboxTreeViewer

CheckboxTreeViewer with special behaviour of the checked / gray state on container (non-leaf) nodes: The grayed state is used to visualize the checked state of its children. Containers are checked and non-gray if all contained leafs are checked. The container is grayed if some but not all leafs are checked.
