| This class is a convenient subclass of Frame that knows how to
handled the WindowClosing event generated when the user requests
that the window be closed. By default it simply closes itself,
which makes it useful for things like modeless dialogs that can be
closed without affecting the rest of the application. Subclasses
of CloseableFrame can override the windowClosing() method if they
want to perform additional actions. Applications that use the
CloseableFrame class for a main window may want to exit when a
CloseableFrame actually closes. They can do this by overriding
windowClosed() or by registering a separate WindowListener to
receive the windowClosed() event. |
