靜态文本 链接控件 背景透明的静态文本

VC中显示文本的控件实在用着不爽，于是自己查了一些资料，自己写一个类，与大家分享：）

使用说明：

1、将该类加入到工程

2、在窗口上添加Static控件并设置相应的ID

3、映射为CTFLinkStaticCtrl类的成员变量

4、初始化

如：m_Link, m_Show

链接效果初始化

 m_Link.TextColorNormal = RGB(0,0,255);
 m_Link.TextColorMouseHover = RGB(0,0,255);
 m_Link.UnderlineNormal = FALSE;
 m_Link.UnderlineMouseHover = TRUE;
 m_Link.Linked = TRUE;

静态文本初始化

 m_Show.TextColorNormal = RGB(255,0,0);
 m_Show.Linked = FALSE;

5、响应点击(只有Linked属性设置为TRUE才响应此事件)

用向导为相应的Static添加OnClick事件

void YourClass::OnLinkClick()

{

    //如果转向网页，则调用

    m_Link.OpenURL(www.baidu.com);

    //如果响应其他功能，则相当于按钮的点击事件，添加你需要的功能

}
