dunno about C#

Post #195,008 by Arkadiy 2/16/05 2:08:59 PM Reply	dunno about C# but the code you describe is essentially Java AWT/Swing event handling mechanism. Has been since 1.1. \ninterface WindowListener\n{\n public void windowClosed(WindowEvent e);\n public void windowClosing(WindowEvent e);\n}\n -- - I was involuntarily self-promoted into management.

However, you can add a delegate to the model group that will get called whenever a search for a model file fails - thus allowing you to prompt the user for it, or implement alternate search paths.

It's a world of madmen and uncertainty and potential mental losses." --George W. Bush

If your idea of "close" is something else, you can use windowClosing() to change the behavior. Also, sometimes Java library provides default implementation of the interfaces involved, which makes it easier to write your own implementation - you don't have to implement all methods. -- - I was involuntarily self-promoted into management.
