That's correct, onChange fires after the text box looses focus, but
you can listen to onkeypress. onKeypress is fired before the text box
is updated allowing you to cancel the keypress if desired. The trick
is to use DeferredCommand.addCommand() to handle the text.
public void onKeyPress(Widget sender, char keyCode, int modifiers){
// check if the keycode is something you are concerned about
DeferredCommand.addCommand(new Command(){
public void execute(){
// read the updated text in the textbox now.
}
});
}
