Examples of org.eclipse.jface.action.IContributionItem

org.eclipse.jface.action.IContributionItem
A contribution item represents a contribution to a shared UI resource such as a menu or tool bar. More generally, contribution items are managed by a contribution manager. For instance, in a tool bar a contribution item is a tool bar button or a separator. In a menu bar a contribution item is a menu, and in a menu a contribution item is a menu item or separator.
A contribution item can realize itself in different SWT widgets, using the different fill methods. The same type of contribution item can be used with a MenuBarManager, ToolBarManager, CoolBarManager, or a StatusLineManager.

This interface is internal to the framework; it should not be implemented outside the framework.
@see IContributionManager @noimplement This interface is not intended to be implemented by clients.
