JFrame - How to trap keyboard events

[BillyKrow]

I have a JFrame and I want to trap keyboard events and make decisions on the event before they actually get sent to components within the JFrame. The problem with the java.awt.event.KeyListener class is that it only listens to events and does not intervene and cannot stop them from happening. Does anybody know how to do this?

If you implement a KeyListener, I believe you have control over what happens on that event - so if you don't want a certain key press event to actually do anything, then you can control that.

See the tutorial

Once you catch an event, it has already "happened". Anyway, you can consume the event so no one else will notice.
