}
3、表格初始化 初始化表格界面效果
// 初始化表格界面
CustomListCtrl m_listInput;
void CTestDlg::OnInitInputCtrl()
{CRect rect;m_listInput.GetClientRect(rect);int nWidth rect.Width() - 15;m_listInput.SetExtendedStyle(LVS_EX_GRIDLINES | LVS_EX_HEADERDRAGDROP | LVS_EX_SUBITEMIMAGES | LVS_EX_FULLROWSELECT);m_listInput.InsertColumn(0, _T(分支号), LVCFMT_CENTER, nWidth * 0.08);m_listInput.InsertColumn(1, _T(名称), LVCFMT_CENTER, nWidth * 0.1);m_listInput.InsertColumn(2, _T(始节点), LVCFMT_CENTER, nWidth * 0.08);m_listInput.InsertColumn(3, _T(终节点), LVCFMT_CENTER, nWidth * 0.08);m_listInput.InsertColumn(4, _T(需风类型), LVCFMT_CENTER, nWidth * 0.1);m_listInput.InsertColumn(5, _T(风阻R), LVCFMT_CENTER, nWidth * 0.1);m_listInput.InsertColumn(6, _T(风阻△R), LVCFMT_CENTER, nWidth * 0.1);m_listInput.InsertColumn(7, _T(需风量Q(m3/s)), LVCFMT_CENTER, nWidth * 0.15);m_listInput.InsertColumn(8, _T(风量△Q), LVCFMT_CENTER, nWidth * 0.14);m_listInput.InsertColumn(9, _T(调节性), LVCFMT_CENTER, nWidth * 0.1);
}4、表格插入内容 // 表格插入内容
void CTestDlg::setInputData()
{m_listInput.DeleteAllItems();std::sort(m_vecInit.begin(), m_vecInit.end());for (int i 0; i m_vecInit.size(); i){stu_GraphParams windResult m_vecInit[i];CString sTmp;// 分支号sTmp.Format(%d, windResult.nNumber);m_listInput.InsertItem(i, sTmp);// 名称m_listInput.SetItemText(i, 1, windResult.sName);// 始节点sTmp.Format(%d, windResult.nStartJunction);m_listInput.SetItemText(i, 2, sTmp);// 终节点sTmp.Format(%d, windResult.nEndJunction);m_listInput.SetItemText(i, 3, sTmp);// 需风类型m_listInput.SetItemText(i, 4, _T(自然));// 风阻CString strResistance;strResistance.Format(%.6f, windResult.dResistance);m_listInput.SetItemText(i, 5, strResistance);// △风阻CString strResistanceEx;strResistanceEx.Format(%.6f, windResult.dResistanceEx);m_listInput.SetItemText(i, 6, strResistanceEx);// 数值改变的话修改单元格颜色bool bChange (strResistanceEx.CompareNoCase(strResistance) ! 0) ? true : false;if(windResult.dResistanceEx 0.000001f bChange){COLORREF cf RGB(255, 0, 0);m_listInput.SetItemColor(6,i,cf);}// 需风量sTmp.Format(%.3f, windResult.dFlowRate);m_listInput.SetItemText(i, 7, sTmp);// 风量sTmp.Format(%.3f, windResult.dFlowRateEx);m_listInput.SetItemText(i, 8, sTmp);// 调节性bool bAdjust windResult.bAdjust;if (bAdjust){m_listInput.SetItemText(i, 9, _T(是));}else{m_listInput.SetItemText(i, 9, _T(否));}}
}5、双击获取表格选中行的内容
// 双击事件
void CTestDlg::OnNMDblclkInputList(NMHDR* pNMHDR, LRESULT* pResult)
{LPNMITEMACTIVATE pNMItemActivate reinterpret_castLPNMITEMACTIVATE(pNMHDR);*pResult 0;// TODO: 在此添加控件通知处理程序代码int nIndex m_listInput.GetNextItem(-1, LVIS_SELECTED);POSITION ps m_listInput.GetFirstSelectedItemPosition();if (NULL ps){return;}int nItem m_listInput.GetNextSelectedItem(ps);stu_WindEdgeInfo windEdgeInfo;windEdgeInfo.sEdgeId m_listInput.GetItemText(nItem, 0);windEdgeInfo.sName m_listInput.GetItemText(nItem, 1);windEdgeInfo.sStartIndex m_listInput.GetItemText(nItem, 2);
}
