Dynamic rolling effect of Swing Components

I don't know when. The carousel effect is popular on the webpage.
At present, swing has not seen any related performance components... today I wrote ..

 

Dynamically scroll the component to a certain direction ..

In fact, it is not difficult to analyze ..
Two jbuttons, one JList, and one JScrollPanel. You can do it in the next animation.
Because I used my own extension package... so in some places, you can change it... for example, change IButton to JButton ..
Currently, only scroll left .. I have left you with a small question .. I hope you can do everything you can to scroll right... if yes. you can contact me for your name on the blog. update code
