Class AWTKeyboardDisabler

java.lang.Object
  java.awt.EventQueue
      fr.emn.reactiveinput.system.AWTKeyboardDisabler

All Implemented Interfaces:

StdInputDisabler

public class AWTKeyboardDisabler

extends java.awt.EventQueue

implements StdInputDisabler

Disables key events for the whole java application. Only Alt+C events are enabled. Individual frame disabling is not supported, so calling install() with a non-null frame won't work. An AWTEventListener can be provided as context in install() method for listening to keyboard events BEFORE they are blocked.
