B4J Question Is it possible to disable key listeners, and how ?

How about doing nothing in the "KeyPressed_Event"?

Or (untested):

...no RemoveEventFilter at B4J ????

see the "picture"...

When you no longer want an event filter to process events for a node or for an event type, remove the filter using the removeEventFilter() method. This method takes the event type and the filter as arguments. In Example 3-2, the filter defined in Example 3-1 is removed from the MouseEvent.MOUSE_PRESSED event for myNode1. The filter is still executed by myNode2 and by myNode1 for the KeyEvent.KEY_PRESSED event.

Example 3-2 Remove a Filter
// Remove an event filter
myNode1.removeEventFilter(MouseEvent.MOUSE_PRESSED, filter);

From https://docs.oracle.com/javafx/2/events/filters.htm

How this can implement at b4j..?
