I want to perform a specific action anytime a certain key combination is pressed while the program is running even if the window is not in focus. For instance, if I press CTRL-U the program would exit. Is this possible?

  • This is not supported by Java. Java can only respond to KeyEvents when a window is in focus. You need to use JNI (which I know nothing about) or another language that does allow access to the OS. Commented Sep 19, 2010 at 21:37

  • @camickr, JNA might be easier to deal with, most of the Windows APIs already have C interfaces... Commented Sep 30, 2010 at 1:51

Your only real option for this is a lot of JNI. However, this can be quite cumbersome and hard to achieve. My advice is to either go straight C/C++ or not attempt this.

Simply put, the only way it can be done is with JNI.
