Example 1 with KeyEventPostProcessor

use of java.awt.KeyEventPostProcessor in project jdk8u_jdk by JetBrains.

the class UIManager method initialize.

    // Install a hook that will be invoked if no one consumes the
    // KeyEvent.  If the source isn't a JComponent this will process
    // key bindings, if the source is a JComponent it implies that
    // processKeyEvent was already invoked and thus no need to process
    // the bindings again, unless the Component is disabled, in which
    // case KeyEvents will no longer be dispatched to it so that we
    // handle it here.
