public class ClearFileAction
extends AbstractSaveUnsavedChangesAction

Clears (empties) the contents of the active view.

This action is called when the user selects the Clear item in the File menu. The menu item is automatically created by the application.

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 NewWindowAction, LoadFileAction, LoadDirectoryAction and CloseFileAction. This action should not be used together with NewFileAction.
