mfc的ClistCtrl控件列的排序

在网上看了许多排序的方法,都没看懂,初学者的悲剧,然后就自己弄了个,请大家指正.

ClistCtrl控件的行带着一个结构体,不过那结构体不好懂,看得眼花缭乱.好多也弄不明白,就自己写了个结构体,把一行的数据全写入结构体中,

交换两结构体的数据就简单多了.

typedef struct

{

wchar_t id[6];  //编号

wchar_t name[10]; //姓名

wchar_t sex[2];        //性别

int age;              //年龄

wchar_t fenlei[6];  //分类

wchar_t tel[12];       //电话

}myTongXiLu;

[.cpp]

写两个函数,把结构体写入指定行中,一个从指定行中的数据写入结构体中

//写入

void CMFCApp_CFile_testDlg::SetItemInofToxiluJG(int selIndex,myTongXiLu* toxilu)

{

CString str;

m_list.SetItemText(selIndex, 0, LPCTSTR(toxilu->id));

m_list.SetItemText(selIndex, 1, toxilu->name);

m_list.SetItemText(selIndex, 2, toxilu->sex);

str.Format(_T("%d"), toxilu->age);

m_list.SetItemText(selIndex, 3, str);

m_list.SetItemText(selIndex, 4, toxilu->fenlei);

m_list.SetItemText(selIndex, 5, toxilu->tel);

}

//读取数据

myTongXiLu CMFCApp_CFile_testDlg::GetToxiluJGInofItem(int selIndex)

{

CString str;

myTongXiLu toxilu;

_tcscpy_s(toxilu.id, m_list.GetItemText(selIndex, 0));

_tcscpy_s(toxilu.name, m_list.GetItemText(selIndex, 1));

_tcscpy_s(toxilu.sex, m_list.GetItemText(selIndex, 2));

str = m_list.GetItemText(selIndex, 3);

if (!str.IsEmpty() ||str.SpanIncluding(_T("0123456789"))==str)

toxilu.age = _ttoi(str);

else

{

toxilu.age = 0;

}

_tcscpy_s(toxilu.fenlei, m_list.GetItemText(selIndex, 4));

_tcscpy_s(toxilu.tel, m_list.GetItemText(selIndex, 5));

return toxilu;

}

接下来就是数据交换了,有的还要转换数字,我就懒得转换了,全是以字符串来比较,

rowInt:为要比较的总行数,原来没弄这参数,每次都要全部比较,所以后来弄个限制行数,比较了的行就不再比较,依次递减.

ColInt:为要比较的列的索引

bol:为true为升序,为flase为降序,

void CMFCApp_CFile_testDlg::CListCtrlShort(int rowInt,int ColInt, bool bol /*= true*/)

{

CListCtrl* pList = (CListCtrl*)GetDlgItem(IDC_LIST1);

myTongXiLu toxi1, toxi2;

CString str1, str2;

int n = 0;

for (int i = 0; i<rowInt-1; i++)

{

toxi1 = GetToxiluJGInofItem(i);

toxi2 = GetToxiluJGInofItem(i + 1);

str1 = pList->GetItemText(i, ColInt);

str2 = pList->GetItemText(i + 1, ColInt);

n = StrCmpW(str1, str2);

if (bol = true)//判断是升序还是降序,为true为升序

{

if (n>0)

{

/*toxiT = toxi1;

toxi1 = toxi2;

toxi2 = toxiT;*/

SetItemInofToxiluJG(i, &toxi2);

SetItemInofToxiluJG(i + 1, &toxi1);

}

}

else

{

if (n < 0)

{

SetItemInofToxiluJG(i, &toxi2);

SetItemInofToxiluJG(i + 1, &toxi1);

}

}

}

}

//鼠标点击列表头事件

void CMFCApp_CFile_testDlg::OnHdnItemclickList1(NMHDR *pNMHDR, LRESULT *pResult)

{

*pResult = 0;

int colInt;

NMLISTVIEW* pListView = (NMLISTVIEW*)pNMHDR;

if (-1 != pListView->iItem)

{

colInt = pListView->iItem;//获得鼠标点击的列的索引

/*CString str;

str.Format(_T("item: %d, subitem: %d"), pListView->iItem, pListView->iSubItem);

AfxMessageBox(str);*/

}

//循环比较,最大的放最后,依次递减

for (int j=m_list.GetItemCount();j>=1;j--)

{

CListCtrlShort(j,colInt,true);

}

}

大功告成,以后再去学习它自带的结构体.
