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.
首先声明:这个效果属于Twitter,本文仅仅是WPF技术交流,看看WPF怎么实现这样的效果,如果用于其他用途,人家来找你麻烦的话,自己负责,与本文无关.
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.
