KeyPressListener for numpad plus

Is there some special magic required for listening on the numpad ‘+’?

I’m trying to use + for adding one to a number in a TextField but with the below sample, I only get a reaction from the Enter key…

		field.addKeyPressListener(Key.ENTER, e -> {"Enter");
		field.addKeyPressListener(Key.ADD, e -> {"Plus");

I can do a generic

		field.addKeyPressListener(e -> {
			if (e.getKey().getKeys().iterator().next().equals("+")) {"+");

which works (and shows that it’s a different key from Key.ADD)

You actually have


for that case

Ah, I’ll have a look. A bit confusing when Key.ADD has the description “The numeric keypad’s addition key, +.”
