/**
* Fired when a keyboard action generates a character. This occurs after onKeyDown and onKeyUp are
* fired for the physical key that was pressed.
*
* <p>It should be noted that many browsers do not generate keypress events for non-printing
* keyCode values, such as KEY_ENTER or arrow keys. These keyCodes can be reliably captured either
* with onKeyDown(Widget, char, int) or onKeyUp(Widget, char, int).
*
* <p>Subclasses that override this method must call <tt>super.onKeyPress(sender, keyCode,
* modifiers)</tt> to ensure that the Widget recieves its events.
*
* @param sender the widget that was focused when the event occurred.
* @see com.google.gwt.user.client.ui.KeyboardListener
