代码示例

代码示例来源：origin: com.google.gwt/gwt-servlet

@Override
protected void onAttach() {
 super.onAttach();
 /*
  * Attach the event listener in onAttach instead of onLoad so users cannot
  * accidentally override it.
  */
 Event.setEventListener(getScrollableElement(), this);
}

代码示例来源：origin: com.google.gwt/gwt-servlet

@Override
 protected void onDetach() {
  /*
   * Detach the event listener in onDetach instead of onUnload so users cannot
   * accidentally override it.
   */
  Event.setEventListener(getScrollableElement(), null);

  super.onDetach();
 }
}

@Override

 /*
  * Attach the event listener in onAttach instead of onLoad so users cannot
  * accidentally override it. If the scrollable element is the same as the
  * root element, then we set the event listener twice (once in
  * super.onAttach() and once here), which is fine.
  */
 Event.setEventListener(getScrollableElement(), this);
}
