Direct Known Subclasses:

LoadDirectoryAction

public class LoadFileAction
extends AbstractSaveUnsavedChangesAction

Lets the user save unsaved changes of the active view, then presents an URIChooser and loads the selected URI into the active view.

This action is called when the user selects the Load 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 do not automatically create a new view for each opened file. This action goes together with ClearFileAction, NewWindowAction, LoadFileAction, LoadDirectoryAction and CloseFileAction. This action should not be used together with OpenFileAction.

Features

Open last URI on launch
When the application is started, the last opened URI is opened in a view.
LoadFileAction 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, LoadFileAction prevents exporting to an URI which is opened in another view.
See org.jhotdraw.app for a description of the feature.
