1、CListCtrl设置行高CListCtrl改变行高：1. 表的修改新建一个MFC类CMyListCtrl,其基类为CListCtrl，属性Owner Draw Fixed设置为TRUE;添加变量CMyListCtrl m_List;MyListCtrl.h文件里，添加变量int m_nRowHeight;2、重载DrawItem()实现自绘,实现请参照以下代码。 手动添加消息宏ON_WM_MEASUREITEM_REFLECT(),添加下面的函数,实现修改行高。 void CMyListCtrl:MeasureItem(LPMEASUREITEMSTRUCT lpMeasureItemStr

2、uct)if (m_nRowHeight0)lpMeasureItemStruct-itemHeight = m_nRowHeight;3、添加ON_WM_MEASUREITEM，响应消息处理OnMeasureItem() void CMyListCtrl:OnMeasureItem(int nIDCtl, LPMEASUREITEMSTRUCT lpMeasureItemStruct)/ TODO: 在此添加消息处理程序代码和/或调用默认值CListCtrl:OnMeasureItem(nIDCtl, lpMeasureItemStruct);4、void CMyListCtrl:SetRo

3、wHeigt(int nHeight) /高置行高(别忘了在.h里添加void SetRowHeigt(int nHeight) ；)m_nRowHeight = nHeight;CRect rcWin;GetWindowRect(&rcWin);WINDOWPOS wp;wp.hwnd = m_hWnd;wp.cx = rcWin.Width();wp.cy = rcWin.Height();wp.flags = SWP_NOACTIVATE | SWP_NOMOVE | SWP_NOOWNERZORDER | SWP_NOZORDER;SendMessage(WM_WINDOWPOSCHA

4、NGED, 0, (LPARAM)&wp);5、重画列表控件，重载DrawItem，添加ON_WM_DRAWITEM()；(别忘了在.h里添加void DrawItem(LPDRAWITEMSTRUCT lpMeasureItemStruct) ；)void CMyListCtrl:DrawItem(LPDRAWITEMSTRUCT lpMeasureItemStruct) CDC* pDC = CDC:FromHandle(lpMeasureItemStruct-hDC); LVITEM lvi = 0; lvi.mask = LVIF_STATE;/|LVIF_IMAGE; lvi.sta

5、teMask = LVIS_FOCUSED | LVIS_SELECTED ; lvi.iItem = lpMeasureItemStruct-itemID; BOOL bGet = GetItem(&lvi);/高亮显示BOOL bHighlight =(lvi.state & LVIS_DROPHILITED)|(lvi.state & LVIS_SELECTED) & (GetFocus() = this)| (GetStyle() & LVS_SHOWSELALWAYS); / 画文本背景 CRect rcBack = lpMeasureItemStruct-rcItem; pDC-S

6、etBkMode(TRANSPARENT); if( bHighlight ) /如果被选中 pDC-SetTextColor(RGB(255,255,255); /文本为白色pDC-FillRect(rcBack, &CBrush(RGB(90,162,0); else pDC-SetTextColor(RGB(0,0,0); /文本为黑色pDC-FillRect(rcBack, &CBrush(RGB(255,255,255); if (lpMeasureItemStruct-itemAction & ODA_DRAWENTIRE) /写文本 CString szText; int nCo

7、llumn = GetHeaderCtrl()-GetItemCount();/列数 for (int i = 0; i GetItemCount(); i+) /循环得到文本 CRect rcItem; if ( !GetSubItemRect(lpMeasureItemStruct-itemID, i, LVIR_LABEL, rcItem ) continue; szText = GetItemText( lpMeasureItemStruct-itemID, i ); rcItem.left += 5; rcItem.right -= 1; pDC-DrawText(szText, l

8、strlen(szText), &rcItem, DT_LEFT | DT_VCENTER | DT_NOPREFIX | DT_SINGLELINE)； 6、含有此列表控件的主对话框OnInitDialog里，BOOL CListCtrlDlg:OnInitDialog()CDialog:OnInitDialog();/ 设置此对话框的图标。当应用程序主窗口不是对话框时，框架将自动/ 执行此操作SetIcon(m_hIcon, TRUE);/ 设置大图标SetIcon(m_hIcon, FALSE);/ 设置小图标/ TODO: 在此添加额外的初始化代码InitDlg();/调用列表控件初始

9、化InitDlg()return TRUE; / 除非将焦点设置到控件，否则返回 TRUE7、void CListCtrlDlg:InitDlg()(别忘了在.h里添加void InitDlg()；)m_List.SetExtendedStyle( m_List.GetExtendedStyle() | LVS_EX_GRIDLINES | LVS_EX_FULLROWSELECT );/ determine the columns m_List.InsertColumn( 0, L名称);m_List.InsertColumn( 1, L消息详情);m_List.SetColumnWidth

10、( 0, 220);m_List.SetColumnWidth( 1,243);m_List.InsertItem(0,L检查轴位);/插入行m_List.InsertItem(1,L故障尺寸);m_List.InsertItem(2,L尺寸单位);m_List.InsertItem(3,L处理关门);m_List.SetItemText(0,1,LL1);/默认显示m_List.SetItemText(1,1,L0);m_List.SetItemText(2,1,Lmm);m_List.SetItemText(3,1,L是);m_List.SetRowHeigt(74);/调用设置行高m_List.SetItemState(0, LVIS_SELECTED, LVIS_SELECTED);完成，效果如下图所示：
