All Implemented Interfaces:

Command

public class SwtOpenCommand

extends AbstractOpenCommand

This command, to be used within applications in a SWT context, opens an existing GraphDocument and adds it to the MDIComponent of the application.

This class uses a SwtGraphFileChooserDialog to allow users to choose a document to open, and most of the work is delegated to the ApplicationFrame.openDocument(File) method.
