CListBox用法總結

基本用法

屬性StyleSelection  Single   --- 單選  Multiple --- 多選(LBS_MULTIPLESEL)  None     --- 不可選(LBS_NOSEL)Sort  對應Style: LBS_SORT

Insert Itemint AddString(LPCTSTR lpszItem);int InsertString(int nIndex,                 LPCTSTR lpszItem);

Delete Itemint DeleteString(UINT nIndex);//清空void ResetContent();  

Selectionint GetCurSel( ) const;int SetCurSel(int nSelect);int GetSelCount( ) const;int GetSelItems(int nMaxItems,                 LPINT rgIndex) const;程式碼範例：擷取選中項並輸出假設CListBox控制項變數名為m_lbTest
// 1.Selection = Single-----------------------------------int nSelIndex = m_lbTest.GetCurSel();if (nSelIndex == LB_ERR)//no item is currently selected{AfxMessageBox(TEXT("no item is currently selected"));}else{CString cstr;m_lbTest.GetText(nSelIndex, cstr);AfxMessageBox(cstr);}// 2.Selection = Multiple----------------------------------int nSelCnt = m_lbTest.GetSelCount();if (nSelCnt == LB_ERR)    //the list box is a single-selection list box{AfxMessageBox(TEXT("the list box is a single-selection list box"));return;}if (nSelCnt == 0)//no item is currently selected{AfxMessageBox(TEXT("no item is currently selected"));return;}int* pnSelIndex = new int[nSelCnt];m_lbTest.GetSelItems(nSelCnt, pnSelIndex);for (int i=0; i<nSelCnt; ++i){CString cstr;m_lbTest.GetText(pnSelIndex[i], cstr);AfxMessageBox(cstr);}delete[] pnSelIndex;
Other// 擷取Textvoid GetText(int nIndex,             CString& rString) const;// Get/Set item associated dataDWORD_PTR GetItemData(int nIndex) const;int SetItemData(int nIndex,        DWORD_PTR dwItemData);注意：1.GetItemData在沒有通過SetItemData設定每一項的關聯資料時返回NULL.2.對應的GetItemDataPtr,SetItemDataPtr其實和GetItemData,SetItemData本質上是一模一樣的  我們可以看下源碼int CListBox::SetItemDataPtr(int nIndex, void* pData){ return SetItemData(nIndex, (DWORD_PTR)(LPVOID)pData); } 看來增加這兩個函數只是使意義更明確些，有點不懂微軟了。
動態建立CListBox控制項
