基本上你可以做的是建立一个事件时，preSS按钮，然后有一个监听器，并有听众引发的变化。看看我的问题的更多细节。如果你看一看接受的答案，你会看到一个很好的例子，我做了。

Basically what you can do is set up an event for when they press the button and then have a listener and have the listener trigger the change. Take a look at my question for more detail. If you take a look at the accepted answer you will see a great example i made.
