超级CListCtrl

// MyHeaderListCtrl.cpp : 实现文件 // /* 采用自绘的方法如何改变行高（该方法必需要自绘属性）： 1)手动添加响应消息 ON_WM_MEASUREITEM_REFLECT() 及消息响应函数 MeasureItem,注意此函数并不是OnMeasureItem函数 2)在MeasureItem函数中更改结构体itemHeight的行高值 3)如何触发该消息，一种简单的调用方法是SendMessage(WM_WINDOWPOSCHANGED, 0, (LPARAM)&wp)发送这个消息,具体的请看 SetRowHeigt函数 */ #include "stdafx.h" #include "VEHICLEbusSPY.h" #include "MyDrawOpaintListCtrl.h" IMPLEMENT_DYNAMIC(CMyDrawOpaintListCtrl, CListCtrl) CMyDrawOpaintListCtrl::CMyDrawOpaintListCtrl() { m_ItemHeight=-1;
