How to only allow digits to be entered in a textbox?

[membersound]

Hi,

I have a textbox where I want to user to only enter digits. Moreover I want to prevent him entering other characters. This is what I tried but it does not work:

    @UiHandler("textbox")
    void onInputsKeyPress(KeyPressEvent event) {
        if (!Character.isDigit(event.getCharCode())) {
            ((IntegerBox) event.getSource()).cancelKey();
        }
    }

Any hints?
