CListCtrl设置行高.docxVIP

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 lpMeasureItemStruct){?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::SetRowHeigt(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_WINDOWPOSCHANGED, 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.stateMask = 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-SetBkMode(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 nCollumn = GetHeaderCtrl()-GetItemCount();//列数??????? for
