public class LoadRecentFileAction
extends AbstractSaveUnsavedChangesAction

Lets the user save unsaved changes of the active view, and then loads the specified URI into the active view.

If there is no active view, this action creates a new view and thus acts the same like OpenRecentFileAction.

This action is called when the user selects an item in the Recent Files submenu of the File menu. The action and the menu item is automatically created by the application, when the ApplicationModel provides a LoadFileAction.
