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?
