public abstract class ActionGroup

extends Object

An ActionGroup represents a group of actions which are added to a context menu, or the action bars of a part, together. The group is given a context which can be used to determine which actions are added, and what their enabled state should be.

This class is intended only as a convenience for managing groups of actions. Clients are not required to use this class in order to add actions to context menus or action bars.

Clients should subclass this class and extend or override the appropriate fill methods.

Since:
