Reassignment of the key button

[MrChebik]

I have an CodeArea, and this event:

this.setOnKeyTyped(event -> {
    if (event.getCharacter().equals("\t")) {
        this.insertText(this.getCaretPosition(), "    ");
        event.consume();
    }
});

I want to change width of tab key, but event.consume() does not work and I get previous \t and four spaces after \t:

|
_______    |

key	explanation
I	caret
_	width of tab
space	my inserted text

Have you read GenericStyledArea's class' javadoc? I believe it specifies that you aren't supposed to use setOn[Event](handler), but rather the code pattern found in Override Behavior Demo

Thank you!
