一个效果很好的outlookbar控件CXTOutBarCtrl
作者：许昌元

下载本文示例源代码



该控件来源于Xtreme Toolkit,我对其进行了修改，使其不依赖于类库独立存在，由于我没有运用XT的其他类，可能你会觉得它没有在类库中的华丽，但相对于其小巧的体格而言，已经很难得了。

源文件包括两个头文件，两个执行文件：XTMemDC.h，XTMemDC.cpp,XTOutBarCtrl.h,XTOutBarCtrl.cpp.

其中XTMemDC是一个CDC继承类，用于辅助功能。

该控件的使用方法：

1、用mfc sdi wizard生成一个子SDI程序。

2、在MainFrm.h头部加入#include "XTOutBarCtrl.h"

3、在MainFrm.h是加入成员变量

CXTOutBarCtrl	m_wndOutlookBar;
