C# 实现简易QQ界面

做了一个简易的ＱＱ界面

１　功能：点击　我的好友会出现好友列表

　　　　　点击　ＱＱ群会出现QQ群列表

                点击   最近联系人 会出现联系人列表

               点击   右上方的叉叉 就能关闭了

实现步骤

把窗口的FormBorderStyle设置为none

再把背景图片设置为QQ界面

然后拖一个panel到窗口中

再拖3个 button和一个listview到panel中

拖到panel中  你就可以设置定位

比如把QQ群这个按钮设置到panel的底部

再拖两个 imagelist

为了保存好友的头像和群组的头像

具体代码如下

还有一个要点是 Dock根据拖进窗口的先后来排优先级

因为这个我浪费了很多时间

一直想不明白
