Direct Known Subclasses:

OpenDirectoryAction

public class OpenFileAction
extends AbstractApplicationAction

Presents an URIChooser and loads the selected URI into an empty view. If no empty view is available, a new view is created.

This action is called when the user selects the Open item in the File menu. The menu item is automatically created by the application. A Recent Files sub-menu is also automatically generated.

If you want this behavior in your application, you have to create it and put it in your ApplicationModel in method ApplicationModel.initApplication(org.jhotdraw.app.Application).

This action is designed for applications which automatically create a new view for each opened file. This action goes together with NewFileAction, OpenDirectoryAction and CloseFileAction. This action should not be used together with LoadFileAction.

Features

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

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