前段时间因为要在原来的软件上增加一个快捷键提示窗体，这个提示窗要求在显示的时候比较醒目美观能引起用户注意，显示后不影响用户操作，能够关掉。很自然的就想到了Messenger那个从屏幕右下角逐渐弹出的消息提示窗体，不过相对Messenger我更喜欢QQ2004奥运版的配色风格，反正都是偷就多偷点吧，下面快捷键提示窗的最终效果：
这个窗体有以下几个特点：
1、显示的时候是从屏幕右下角逐渐弹出的；
2、它是个无标题窗体，但它必须允许用户移动和改变大小，因此要用到无标题窗体拖动、改变大小的技术；
3、它是个不规则的窗体，主要是左上角和右上角是圆形导角，因此要为窗体创建外形，且窗体改变大小时必须重建；
4、它标题和内容显示区都有渐层色，标题还有几个小点点，在实现时使用取巧的方法，直接利用截图进行填充。
当然界面可以偷，代码就得老老实实的写的了，下面是界面设计图和实现代码：
