MFC 写的一个分页控件，分享一下

Question

写了个MFC的分页控件，分享一下。使用方法：1、分页控件父窗体继承CPagerNotify类，并重写virtual void OnGotoPager(int nIndex)方法2、声明变量 CPagerCtrlEx m_Pager;3、在窗体的OnInitDialog()方法中写入下面代码设置图片： m_Pager.Create(CPoint(200,200),this); // 第一个参数为控件坐标 m_Pager.SetNotifyManager(this);
 m_Pager.SetProperty(20,1);
 m_Pager.SetBitmaps(ITEM_FIRST,IDB_PAGER_1_1, IDB_PAGER_1_2, IDB_PAGER_1_3, IDB_PAGER_1_1);
 m_Pager.SetBitmaps(ITEM_PREV,IDB_PAGER_2_1, IDB_PAGER_2_2, IDB_PAGER_2_3, IDB_PAGER_2_1);
 m_Pager.SetBitmaps(ITEM_NEXT,IDB_PAGER_3_1, IDB_PAGER_3_2, IDB_PAGER_3_3, IDB_PAGER_3_1);
 m_Pager.SetBitmaps(ITEM_LAST,IDB_PAGER_4_1, IDB_PAGER_4_2, IDB_PAGER_4_3, IDB_PAGER_4_1);4、效果图如下：5、例子下载：http://download.csdn.net/source/3025013本文来自CSDN博客，转载请标明出处：http://blog.csdn.net/yfqvip/archive/2011/02/16/6188451.aspx
