CListCtrl使用技巧

??????????????????????????????????????

CListCtrl使用技巧

以下未經說明，listctrl默認view 風格為report

1. CListCtrl 風格

????? LVS_ICON: 為每個item顯示大圖標
????? LVS_SMALLICON: 為每個item顯示小圖標
????? LVS_LIST: 顯示一列帶有小圖標的item
????? LVS_REPORT: 顯示item詳細資料

????? 直觀的理解：windows資源管理器，“查看”標簽下的“大圖標，小圖標，列表，詳細資料”

2. 設置listctrl 風格及擴展風格

????? LONG lStyle;
????? lStyle = GetWindowLong(m_list.m_hWnd, GWL_STYLE);//獲取當前窗口style
????? lStyle &= ~LVS_TYPEMASK; //清除顯示方式位
????? lStyle |= LVS_REPORT; //設置style
????? SetWindowLong(m_list.m_hWnd, GWL_STYLE, lStyle);//設置style
?
????? DWORD dwStyle = m_list.GetExtendedStyle();
????? dwStyle |= LVS_EX_FULLROWSELECT;//選中某行使整行高亮（只適用與report風格的listctrl）
????? dwStyle |= LVS_EX_GRIDLINES;//網格線（只適用與report風格的listctrl）
????? dwStyle |= LVS_EX_CHECKBOXES;//item前生成checkbox控件
????? m_list.SetExtendedStyle(dwStyle); //設置擴展風格
?
????? 注：listview的style請查閱msdn
????? http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceshellui5/html/wce50lrflistviewstyles.asp

?

3. 插入數據

????? m_list.InsertColumn( 0, "ID", LVCFMT_LEFT, 40 );//插入列
????? m_list.InsertColumn( 1, "NAME", LVCFMT_LEFT, 50 );
????? int nRow = m_list.InsertItem(0, “11”);//插入行
????? m_list.SetItemText(nRow, 1, “jacky”);//設置數據

?

4. 一直選中item

??? 選中style中的Show selection always，或者在上面第2點中設置LVS_SHOWSELALWAYS

5. 選中和取消選中一行

??? int nIndex = 0;
??? //選中
??? m_list.SetItemState(nIndex, LVIS_SELECTED|LVIS_FOCUSED, LVIS_SELECTED|LVIS_FOCUSED);
??? //取消選中
??? m_list.SetItemState(nIndex, 0, LVIS_SELECTED|LVIS_FOCUSED);
?

6. 得到listctrl中所有行的checkbox的狀態

????? m_list.SetExtendedStyle(LVS_EX_CHECKBOXES);
????? CString str;
????? for(int i=0; i<m_list.GetItemCount(); i++)
????? {
?????????? if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED || m_list.GetCheck(i))
?????????? {
??????????????? str.Format(_T("第%d行的checkbox為選中狀態"), i);
??????????????? AfxMessageBox(str);
?????????? }
????? }

7. 得到listctrl中所有選中行的序號

????? 方法一：
????? CString str;
????? for(int i=0; i<m_list.GetItemCount(); i++)
????? {
?????????? if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED )
?????????? {
??????????????? str.Format(_T("選中了第%d行"), i);
??????????????? AfxMessageBox(str);
?????????? }
????? }

????? 方法二：
????? POSITION pos = m_list.GetFirstSelectedItemPosition();
????? if (pos == NULL)
?????????? TRACE0("No items were selected!\n");
????? else
????? {
?????????? while (pos)
?????????? {
??????????????? int nItem = m_list.GetNextSelectedItem(pos);
??????????????? TRACE1("Item %d was selected!\n", nItem);
??????????????? // you could do your own processing on nItem here
?????????? }
????? }

8. 得到item的信息

????? TCHAR szBuf[1024];
????? LVITEM lvi;
????? lvi.iItem = nItemIndex;
????? lvi.iSubItem = 0;
????? lvi.mask = LVIF_TEXT;
????? lvi.pszText = szBuf;
????? lvi.cchTextMax = 1024;
????? m_list.GetItem(&lvi);

????? 關于得到設置item的狀態，還可以參考msdn文章
????? Q173242: Use Masks to Set/Get Item States in CListCtrl
?????????????? http://support.microsoft.com/kb/173242/en-us

9. 得到listctrl的所有列的header字符串內容

????? LVCOLUMN lvcol;
????? char? str[256];
????? int?? nColNum;
????? CString? strColumnName[4];//假如有4列

????? nColNum = 0;
????? lvcol.mask = LVCF_TEXT;
????? lvcol.pszText = str;
????? lvcol.cchTextMax = 256;
????? while(m_list.GetColumn(nColNum, &lvcol))
????? {
?????????? strColumnName[nColNum] = lvcol.pszText;
?????????? nColNum++;
????? }

10. 使listctrl中一項可見，即滾動滾動條

??? m_list.EnsureVisible(i, FALSE);

11. 得到listctrl列數

??? int nHeadNum = m_list.GetHeaderCtrl()->GetItemCount();

12. 刪除所有列

??? ? 方法一：
???? ??? while ( m_list.DeleteColumn (0))
??? ?? 因為你刪除了第一列后，后面的列會依次向上移動。

??? ? 方法二：
????? int nColumns = 4;
????? for (int i=nColumns-1; i>=0; i--)
????? ??? m_list.DeleteColumn (i);

13. 得到單擊的listctrl的行列號

????? 添加listctrl控件的NM_CLICK消息相應函數
????? void CTest6Dlg::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult)
????? {
?????????? // 方法一：
?????????? /*
?????????? DWORD dwPos = GetMessagePos();
?????????? CPoint point( LOWORD(dwPos), HIWORD(dwPos) );
??
?????????? m_list.ScreenToClient(&point);
??
?????????? LVHITTESTINFO lvinfo;
?????????? lvinfo.pt = point;
?????????? lvinfo.flags = LVHT_ABOVE;
????
?????????? int nItem = m_list.SubItemHitTest(&lvinfo);
?????????? if(nItem != -1)
?????????? {
??????????????? CString strtemp;
??????????????? strtemp.Format("單擊的是第%d行第%d列", lvinfo.iItem, lvinfo.iSubItem);
??????????????? AfxMessageBox(strtemp);
?????????? }
????????? */
??
????????? // 方法二:
????????? /*
?????????? NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
?????????? if(pNMListView->iItem != -1)
?????????? {
??????????????? CString strtemp;
??????????????? strtemp.Format("單擊的是第%d行第%d列",
??????????????????????????????? pNMListView->iItem, pNMListView->iSubItem);
??????????????? AfxMessageBox(strtemp);
?????????? }
????????? */
?????????? *pResult = 0;
????? }

?

14. 判斷是否點擊在listctrl的checkbox上

????? 添加listctrl控件的NM_CLICK消息相應函數
????? void CTest6Dlg::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult)
????? {
?????????? DWORD dwPos = GetMessagePos();
?????????? CPoint point( LOWORD(dwPos), HIWORD(dwPos) );
??
?????????? m_list.ScreenToClient(&point);
??
?????????? LVHITTESTINFO lvinfo;
?????????? lvinfo.pt = point;
?????????? lvinfo.flags = LVHT_ABOVE;
????
?????????? UINT nFlag;
?????????? int nItem = m_list.HitTest(point, &nFlag);
?????????? //判斷是否點在checkbox上
?????????? if(nFlag == LVHT_ONITEMSTATEICON)
?????????? {
??????????????? AfxMessageBox("點在listctrl的checkbox上");
?????????? }
?????????? *pResult = 0;
????? }

15. 右鍵點擊listctrl的item彈出菜單

????? 添加listctrl控件的NM_RCLICK消息相應函數
????? void CTest6Dlg::OnRclickList1(NMHDR* pNMHDR, LRESULT* pResult)
????? {
?????????? NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
?????????? if(pNMListView->iItem != -1)
?????????? {
??????????????? DWORD dwPos = GetMessagePos();
??????????????? CPoint point( LOWORD(dwPos), HIWORD(dwPos) );
???
??????????????? CMenu menu;
??????????????? VERIFY( menu.LoadMenu( IDR_MENU1 ) );
??????????????? CMenu* popup = menu.GetSubMenu(0);
??????????????? ASSERT( popup != NULL );
??????????????? popup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y, this );
?????????? }
?????????? *pResult = 0;
? }

?

16. item切換焦點時(包括用鍵盤和鼠標切換item時)，狀態的一些變化順序

????? 添加listctrl控件的LVN_ITEMCHANGED消息相應函數
????? void CTest6Dlg::OnItemchangedList1(NMHDR* pNMHDR, LRESULT* pResult)
????? {
?????????? NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
?????????? // TODO: Add your control notification handler code here
???
?????????? CString sTemp;
?
?????????? if((pNMListView->uOldState & LVIS_FOCUSED) == LVIS_FOCUSED &&
??????????? (pNMListView->uNewState & LVIS_FOCUSED) == 0)
?????????? {
??????????????? sTemp.Format("%d losted focus",pNMListView->iItem);
?????????? }
?????????? else if((pNMListView->uOldState & LVIS_FOCUSED) == 0 &&
?????????????? (pNMListView->uNewState & LVIS_FOCUSED) == LVIS_FOCUSED)
?????????? {
??????????????? sTemp.Format("%d got focus",pNMListView->iItem);
?????????? }
?
?????????? if((pNMListView->uOldState & LVIS_SELECTED) == LVIS_SELECTED &&
??????????? (pNMListView->uNewState & LVIS_SELECTED) == 0)
?????????? {
??????????????? sTemp.Format("%d losted selected",pNMListView->iItem);
?????????? }
?????????? else if((pNMListView->uOldState & LVIS_SELECTED) == 0 &&
??????????? (pNMListView->uNewState & LVIS_SELECTED) == LVIS_SELECTED)
?????????? {
??????????????? sTemp.Format("%d got selected",pNMListView->iItem);
?????????? }
???
?????????? *pResult = 0;
????? }
