IAction	An action represents the non-UI side of a command which can be triggered by the end user.
IContributionItem	A contribution item represents a contribution to a shared UI resource such as a menu or tool bar.
IContributionManager	A contribution manager organizes contributions to such UI components as menus, toolbars and status lines.
IContributionManagerOverrides	This interface is used by instances of IContributionItem to determine if the values for certain properties have been overriden by their manager.
ICoolBarManager	The ICoolBarManager interface provides protocol for managing contributions to a cool bar.
IMenuCreator	Interface for something that creates and disposes of SWT menus.
IMenuListener	A menu listener that gets informed when a menu is about to show.
IMenuManager	The IMenuManager interface provides protocol for managing contributions to a menu bar and its sub menus.
IStatusLineManager	The IStatusLineManager interface provides protocol for displaying messages on a status line, for monitoring progress, and for managing contributions to the status line.
IToolBarManager	The IToolBarManager interface provides protocol for managing contributions to a tool bar.

Class Summary

AbstractGroupMarker	Abstract superclass for group marker classes.
Action	The standard abstract implementation of an action.
ActionContributionItem	A contribution item which delegates to an action.
ContributionItem	An abstract base implementation for contribution items.
ContributionManager	Abstract base class for all contribution managers, and standard implementation of IContributionManager.
ControlContribution	An abstract contribution item implementation for adding an arbitrary SWT control to a tool bar.
CoolBarManager	A cool bar manager is a contribution manager which realizes itself and its items in a cool bar control.
ExternalActionManager	A manager for a callback facility which is capable of querying external interfaces for additional information about actions and action contribution items.
GroupMarker	A group marker is a special kind of contribution item denoting the beginning of a group.
MenuManager	A menu manager is a contribution manager which realizes itself and its items in a menu control; either as a menu bar, a sub-menu, or a context menu.
Separator	A separator is a special kind of contribution item which acts as a visual separator and, optionally, acts as a group marker.
StatusLineLayoutData	Represents the layout data object for Control within the status line.
StatusLineManager	A status line manager is a contribution manager which realizes itself and its items in a status line control.
SubContributionItem	A SubContributionItem is a wrapper for an IContributionItem.
SubContributionManager	A SubContributionManager is used to define a set of contribution items within a parent manager.
SubCoolBarManager	A SubCoolBarManager monitors the additional and removal of items from a parent manager so that visibility of the entire set can be changed as a unit.
SubMenuManager	A SubMenuManager is used to define a set of contribution items within a parent manager.
SubStatusLineManager	A SubStatusLineManager is used to define a set of contribution items within a parent manager.
SubToolBarManager	A SubToolBarManager monitors the additional and removal of items from a parent manager so that visibility of the entire set can be changed as a unit.

Package org.eclipse.jface.action Description

Provides support for shared UI resources such as menus, tool bars, and status lines.

Package Specification

Contribution managers coordinate contributions to shared UI resources such as menus, menu bars, tool bars, and status lines. ContributionManager maintains the contributions as a dynamic list of contribution items (IContributionItems). Separators (Separator) can be included in contribution lists to break up the list's visual representation. Internally, contribution lists can be organized into named groups via special group markers (GroupMarker) to facilitate programatic insertion at specific positions within the list.

Three specific contribution managers are provided: a status line manager (StatusLineManager), a tool bar manager (ToolBarManager), and a hierarchical menu manager (MenuManager).

Actions (IAction) are commands which can be triggered from the UI, like the ones found in menus, toolbars, and buttons. Menus and tools bars are typically populated with contribution items that delegate to actions (ActionContributionItem).

Note: None of the classes in this package maintain global state.
