Class LoadRecentFileAction

java.lang.Object
  javax.swing.AbstractAction
      org.jhotdraw.app.action.AbstractViewAction

              org.jhotdraw.app.action.file.LoadRecentFileAction

All Implemented Interfaces:

java.awt.event.ActionListener, java.io.Serializable, java.lang.Cloneable, java.util.EventListener, javax.swing.Action

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.

Features

Open last URI on launch
LoadRecentFileAction supplies data for this feature by calling Application.addRecentURI(java.net.URI) when it successfully loaded a file. See org.jhotdraw.app for a description of the feature.

Allow multiple views per URI
When the feature is disabled, LoadRecentFileAction prevents loading an URI which is opened in another view.
See org.jhotdraw.app for a description of the feature.
