All Implemented Interfaces:

public abstract class PerspectiveMenu

extends ContributionItem

A menu for perspective selection.

A PerspectiveMenu is used to populate a menu with perspective shortcut items. If the user selects one of these items an action is performed for the selected perspective.

The visible perspective items within the menu are dynamic and reflect the available set generated by each subclass. The default available set consists of the perspective shortcut list of the current perspective.

This class is abstract. Subclasses must implement the run method, which performs a specialized action for the selected perspective.
