Best way to block KeyEvent

[Lubomir Nerad]

Hi Jiri,

you can consume key events for blocked keys in an event filter. Event 
filter is an EventHandler registered through addEventFilter method. It 
can be registered directly on the focused node or on any of its parent 
nodes, scene or stage.

Example:

         node.addEventFilter(KeyEvent.KEY_PRESSED,
                              new EventHandler<KeyEvent>() {
                                  public void handle(KeyEvent keyEvent) {
                                      if (<key test>) {
                                          keyEvent.consume();
                                      }
                                  }
                              });

For <key test> you can use the KeyCombination.match method.

Regards,
Lubo
