Class CloseWindowAdaptor

com.sas.util.CloseWindowAdaptor

All Implemented Interfaces:

java.awt.event.WindowListener, java.util.EventListener

public class CloseWindowAdaptor
implements java.awt.event.WindowListener

CloseWindowAdaptor is an adaptor object which listens for a WindowEvent and disposes a window (i.e. closes it) when a window receives a close event.

  CloseWindowAdaptor closeAdaptor = new CloseWindowAdaptor(window);
 

is all that is needed to make a window close when it received a close request (normally from the window manager, such as clicking the X icon in Microsoft Windows).

Normally, the adaptor only listens for window events from this window, but you can also add the adaptor as a window listener on other windows. For example, if you have a parent window and a non-modal dialog, you can use a CloseWindowAdaptor to close the dialog when the primary window closes:

  MyAppFrame parent = new MyAppFrame();
  // cause the parent window to close when it receives a close request
  CloseWindowAdaptor closeParent = new CloseWindowAdaptor(parent);
  // create a non-modal dialog
  Dialog d = new Dialog(parent);
  // allow the dialog to close itself
  CloseWindowAdaptor closeDialog = new CloseWindowAdaptor(dialog);
  // Have the parent close the dialog when the parent window closes:
  parent.addWindowListener(closeDialog);
 

The only method in the WindowListener interface that is implemented is windowClosing(windowEvent)
