Hi Alexander,
seems like you're looking for the preventDefault() method.
Call it on the event object in the listener to have it prevent the
execution of the default code.
Imagine you don't want the letter "w","W" in your textfield "tf":
tf.addListener("keypress", function(evt) {
if (evt.getKeyIdentifier() == "W") // Upper case!
{
evt.preventDefault();
}, this);
Otherwise, if you don't want the user to select certain ListItems, you
can check for the selection in the "changeSelection" listener and have
the SelectBox or List instantly resetSelection().
HTH,
greetings,
Stefan
