Every control has a number of xxxHandlers interfaces that you can hang code
off of.
Try something like this using old style (pre-binder) code
// create a text box & add it to a Panel
myTextBox = new TextBox();
// add a handler to the text box control
myTextBox.addValueChangeHandler( new ValueChangeHandler<String>() {
@Override
public void onValueChange(ValueChangeEvent<String> event) {
Boolean isChar = (null == Integer.getInteger( myTextBox.getValue() ));
}
});
