Swing wrapping

Hi there,

Just wondering if anyone has been involved in a project or development where
they wrapped the Swing API behind there own API.

Some Reasons Why:
To have our own events instead of Swing MouseEvents, KeyEvents coming
though to our application.
Also we want to have windows that close automatically on certain events
e.g. closes automatically on a Middle click.
Some key Events have to go to the main window which is a canvas even
though the focus is in another window.

Any information would be gratefully received.

cheers,

Muz

Well, not the entire API, but if you need a custom Swing component
you'll normally either extend the component in question or wrap it in
your custom class. I think every developer who has worked with GUI's
will have done this many times.

Just implement the appropriate listeners.

Simply pass a reference of the canvas on to your other components, add
the appropriate listeners to these components, and send the events that
you capture on to your canvas.
