Class SimpleModalMaker

java.lang.Object
  java.awt.event.WindowAdapter
      edu.iastate.metnet.metaomgraph.SimpleModalMaker

All Implemented Interfaces:

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

public class SimpleModalMaker
extends java.awt.event.WindowAdapter

If you make a Dialog or JDialog modal, it will block ALL frames running in the current application context. In MetaOmGraph, we want modal dialogs to block ONLY the main window. Other frames (such as the Help frame) should remain normal. This class provides a workaround for this problem. By attaching an instance of this class as a WindowListener to a Dialog/JDialog, the desired modal functionality should be achieved. Some notes: 1) If multiple dialogs each use the same instance of this class, the main window won't be re-enabled until all of the dialogs are closed. If multiple dialogs each use their own instance of this class, the main window will be re-enabled when any of the dialogs are closed. Therefore, it's best to use just one instance.
