MFC ListControl用法總結

本文轉自：http://blog.chinaunix.net/uid-26310563-id-3164303.html

1、ListControl初始化

    ListControl初始化代碼添加在虛函數CDlgxxx::OnInitDialog()中：

m_MyList.ModifyStyle(0L,LVS_SHOWSELALWAYS);

DWORD dwStyle = m_MyList.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_MyList.SetExtendedStyle(dwStyle);

//設置列標題

m_MyList.InsertColumn(0,_T(""));

m_MyList.InsertColumn(1,_T("編號"),LVCFMT_CENCTER,80);

m_MyList.InsertColumn(2,_T("名稱"),LVCFMT_LEFT,100);

m_MyList.InsertColumn(3,_T("單價"),LVCFMT_RIGHT,80);

......

//InsertColumn第三個參數可設置爲LVCFMT_LEFT, LVCFMT_RIGHT, or LVCFMT_CENTER

//解決第一列始終靠左的問題

m_MyList.DeleteColumn(0);

2、在ListControl中插入數據

int nItem = m_datalist.GetItemCount();

//獲得列表行數

m_Mylist.InsertItem(nItem, _T("data"));

m_Mylist.SetItemText(nItem, 1, CString);

m_Mylist.SetItemText(nItem, 2, CString);

......

3、刪除選中項（包括多選）

void Dialogxxx::OnBnClickedDelete()

{

// TODO: Add your control notification handler code here

POSITION pos = m_Mylist.GetFirstSelectedItemPosition();

if (pos == NULL) {

AfxMessageBox(_T("No items were selected!\n"));

}

else {

while(pos) {

int nItem = m_Mylist.GetNextSelectedItem(pos);

m_Mylist.DeleteItem(nItem);

// you could do your own processing on nItem here

}

}

}

4、左鍵單擊消息響應函數

    給ListControl控件添加名爲NM_CLICK的消息響應函數

BEGIN_MESSAGE_MAP(CDlgxxx, CDialog)

ON_NOTIFY(NM_CLICK, IDC_LIST, &CDlgxxx::OnNMClickList)

END_MESSAGE_MAP()

    若編譯出錯在NMITEMACTIVATE後添加*

void CDlgxxx::OnNMClickList(NMHDR *pNMHDR, LRESULT *pResult)

{

LPNMITEMACTIVATE pNMItemActivate = reinterpret_cast<NMITEMACTIVATE*>(pNMHDR);

// TODO: Add your control notification handler code here

*pResult = 0;

}

5、單擊列表頭實現按相應列排序

    從CListCtrl繼承一個新類CSortList

class CSortList : public CListCtrl

{

public:

CSortList();

~CSortList();

bool m_fAsc;

int m_nSortedCol;

};

CSortList::CSortList()

: CListCtrl()

{

m_fAsc = FALSE;

m_nSortedCol = 0;

}

CSortList::~CSortList()

{}

    在對話框類中爲CListCtrl控件添加成員變量

CSortList m_datalist;

    添加消息相應函數

afx_msg void OnLvnColumnclickDatalist(NMHDR *pNMHDR, LRESULT *pResult);

BEGIN_MESSAGE_MAP(Dialogxxx, CDialog)

ON_NOTIFY(LVN_COLUMNCLICK, IDC_DATALIST, &DialogC10::OnLvnColumnclickDatalist)

END_MESSAGE_MAP()

void Dialogxxx::OnLvnColumnclickDatalist(NMHDR *pNMHDR, LRESULT *pResult)

{

// LPNMLISTVIEW pNMLV = reinterpret_cast<LPNMLISTVIEW>(pNMHDR);

// TODO: Add your control notification handler code here

NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;

//爲排序設置唯一標示符??

for(int i = 0; i < m_datalist.GetItemCount(); ++i)

m_datalist.SetItemData(i,i);

if(pNMListView->iSubItem == m_datalist.m_nSortedCol) {

m_datalist.m_fAsc = !m_datalist.m_fAsc;

}

else {

m_datalist.m_nSortedCol = pNMListView->iSubItem;

m_datalist.m_fAsc = FALSE;

}

m_datalist.SortItems(MyCompareProc, (DWORD)&m_datalist);//調用排序處理函數MyCompareProc

*pResult = 0;

}

    添加相應處理函數

static int CALLBACK MyCompareProc(LPARAM lParam1, LPARAM lParam2, LPARAM lParamSort) 

{ 

// lParamSort   contains   a   pointer   to   the   list   view   control. 

// The   lParam   of   an   item   is   just   its   index.   

CSortList* pListCtrl = (CSortList*)lParamSort; 

CString strItem1 = pListCtrl->GetItemText(lParam1, pListCtrl->m_nSortedCol); 

CString strItem2 = pListCtrl->GetItemText(lParam2, pListCtrl->m_nSortedCol); 

    //比較兩個數

// LPCTSTR s1=(LPCTSTR)strItem1; 

// LPCTSTR s2=(LPCTSTR)strItem2; 

int n1 = _ttoi(strItem1); 

int n2 = _ttoi(strItem2);

if(pListCtrl->m_fAsc) 

return n1 > n2 ? 1 : -1; 

else 

return n1 < n2 ? 1 : -1;

}
