最近上网看到这个CSS3实现的Twitter按钮,感觉很漂亮,于是想用WPF来实现下.

实现这个效果,参考了CSS3 原文地址:http://www.html5tricks.com/css3-twitter-3d-button.html

我并不知道这是不是原文的出处,我仅仅是在这里看到的.如果原文作者看到,这并不是原文出处,请留言给我.

效果版权属于Twitter,本文仅仅是WPF技术交流

效果如图:

实现这个并没有用到3D,仅仅是一系列动画的组合,使它看起来像3D.

控件模版一共分4大部分:

盒子内部的Content
盒子盖外表皮
盒子盖拉下来后下面的阴影
盒子盖内表皮

里面的"Follow @bennettfeely"是个带下划线的TextBlock,放到了Content里面.外面的"t"放到了Tag里.通过动画控制放缩ScaleTransform来实现.
