C# 高仿腾讯QQ (TextBox控件美化)(附源码)

接上一篇《C# 高仿腾讯QQ (Bottom控件美化) 》

这篇来说一下QQ皮肤TextBox控件的美化：

  (1)．已修正 每次窗口最小化以后再还原会发现窗口底部往下移了几十个像素（但还不十分完善，在设计模式时有BUG，请高手支招）

 

  效果图如下:

 

 

说明：

     （1）新增一个自定义控件（ALTextBox.cs），在上面放一个TextBox控件,把控件的边框属性设为无 (BorderStyle==BorderStyle.None);

           

　　（2）准备一张带有5个状态的按钮图片如

      　　

　　  分别对应5种状态，通过重写OnPaint方法把相应的状态图画进去(其实有几种状态用不到，大家自己去修正吧)

　　  //枚举按钮的状态
   　 public enum State
   　　 {
       　　Normal = 1,//按钮默认时
       　　MouseOver = 2,//鼠标移上按钮时
       　　MouseDown = 3,//鼠标按下按钮时
       　　Disable = 4,//当不启用按钮时（也就是按钮属性Enabled==Ture时）
       　　Default = 5//控件得到Tab焦点时
    　　}
