I would like to lock the mouse inside a JFrame. That is, the mouse can not leave the contents of the JFrame (unless the user hits escape, alt-tab, or the window otherwise looses focus). Ideas?
Thanks!

I’m not sure if there’s a more automatic way of doing that, but you could use the Robot class to set the mouse position. So in the event handler for when the JFrame gains focus you can start watching the mouse move event, and when the mouse moves just make sure it stays within the JFrame. If it leaves the JFrame you can use the Robot class to set the mouse’s position to go back.
Then when the window loses focus, you can unregister from the mouse move event.
