VC之列表控件排序

本文简单介绍下VC列表控件排序功能实现。

1.新建对话框应用程序

新建对话框应用程序，并且添加List列表控件。

2.添加相关变量和函数

class CListSortDlg : public CDialog
{
// Construction
public:
int m_nSortSign2;
int m_nSortSign1;
CListSortDlg(CWnd* pParent = NULL); // standard constructor

// Dialog Data
//{{AFX_DATA(CListSortDlg)
enum { IDD = IDD_LISTSORT_DIALOG };
CListCtrl m_list2;
CListCtrl m_list1;
//}}AFX_DATA

// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CListSortDlg)
protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support
//}}AFX_VIRTUAL

// Implementation
protected:
HICON m_hIcon;

// Generated message map functions
//{{AFX_MSG(CListSortDlg)
virtual BOOL OnInitDialog();
afx_msg void OnSysCommand(UINT nID, LPARAM lParam);
afx_msg void OnPaint();
afx_msg HCURSOR OnQueryDragIcon();
afx_msg void OnColumnclickList1(NMHDR* pNMHDR, LRESULT* pResult);
afx_msg void OnColumnclickList2(NMHDR* pNMHDR, LRESULT* pResult);
//}}AFX_MSG
DECLARE_MESSAGE_MAP()
private:
void SetListInit2();
void SetListInit();
};

3.初始化

初始化变量

SetListInit();
SetListInit2();

m_nSortSign1 = 1;
m_nSortSign2 = 1;

初始化列表

void CListSortDlg::SetListInit()
{
//属性设置
m_list1.ModifyStyle(LVS_TYPEMASK,LVS_REPORT&LVS_TYPEMASK|LVS_SINGLESEL);
DWORD dwStyle = m_list1.GetExtendedStyle();
m_list1.SetExtendedStyle(dwStyle|LVS_EX_FULLROWSELECT|LVS_EX_GRIDLINES);

//设置行宽
CImageList image;
image.Create(1,30,ILC_COLOR24|ILC_MASK,4,0);
m_list1.SetImageList(&image,LVSIL_SMALL);

//设置字体和大小
CFont font;
font.CreateFont(16,0,0,0,FW_NORMAL,FALSE,FALSE,0,ANSI_CHARSET,OUT_DEFAULT_PRECIS,CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,DEFAULT_PITCH|FF_SWISS,"宋体");
m_list1.SetFont(&font);
m_list1.GetHeaderCtrl()->SetFont(&font);

//设置标题头
m_list1.InsertColumn(0,"序号",LVCFMT_LEFT,80,0);
m_list1.InsertColumn(1,"姓名",LVCFMT_LEFT,120,0);
m_list1.InsertColumn(2,"年龄",LVCFMT_LEFT,80,0);

//设置内容
m_list1.InsertItem(0,"001");
m_list1.SetItemText(0,1,"小明");
m_list1.SetItemText(0,2,"18");

m_list1.InsertItem(1,"002");
m_list1.SetItemText(1,1,"小红");
m_list1.SetItemText(1,2,"17");

m_list1.InsertItem(2,"003");
m_list1.SetItemText(2,1,"小华");
m_list1.SetItemText(2,2,"19");
}

void CListSortDlg::SetListInit2()
{
//属性设置
m_list2.ModifyStyle(LVS_TYPEMASK,LVS_REPORT&LVS_TYPEMASK|LVS_SINGLESEL);
DWORD dwStyle = m_list2.GetExtendedStyle();
m_list2.SetExtendedStyle(dwStyle|LVS_EX_FULLROWSELECT|LVS_EX_GRIDLINES);

//设置行宽
CImageList image;
image.Create(1,30,ILC_COLOR24|ILC_MASK,4,0);
m_list2.SetImageList(&image,LVSIL_SMALL);

//设置字体和大小
CFont font;
font.CreateFont(16,0,0,0,FW_NORMAL,FALSE,FALSE,0,ANSI_CHARSET,OUT_DEFAULT_PRECIS,CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,DEFAULT_PITCH|FF_SWISS,"宋体");
m_list2.SetFont(&font);
m_list2.GetHeaderCtrl()->SetFont(&font);

//设置标题头
m_list2.InsertColumn(0,"序号",LVCFMT_LEFT,80,0);
m_list2.InsertColumn(1,"姓名",LVCFMT_LEFT,120,0);
m_list2.InsertColumn(2,"年龄",LVCFMT_LEFT,80,0);

//设置内容
m_list2.InsertItem(0,"001");
m_list2.SetItemText(0,1,"小明");
m_list2.SetItemText(0,2,"18");

m_list2.InsertItem(1,"002");
m_list2.SetItemText(1,1,"小红");
m_list2.SetItemText(1,2,"17");

m_list2.InsertItem(2,"003");
m_list2.SetItemText(2,1,"小华");
m_list2.SetItemText(2,2,"19");
}

4.排序

方案一：只对指定栏排序

系统函数

int CALLBACK SortData1(LPARAM lParam1, LPARAM lParam2, LPARAM lParamSort)
{
CListSortDlg* pDlg = (CListSortDlg*)lParamSort;
if (!pDlg)
{
return 0;
}

CListCtrl &list = (CListCtrl&)(pDlg->m_list1);

WORD wSubItem = 0;
WORD nItem1 = lParam1;
WORD nItem2 = lParam2;

CString sItem1 = list.GetItemText(nItem1,wSubItem);
CString sItem2 = list.GetItemText(nItem2,wSubItem);

if (sItem1 < sItem2)
{
return pDlg->m_nSortSign1;
}
else
{
return -1*pDlg->m_nSortSign1;
}

return 0;
}

排序事件

void CListSortDlg::OnColumnclickList1(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
// TODO: Add your control notification handler code here
LPNMLISTVIEW pNMLV = reinterpret_cast<LPNMLISTVIEW>(pNMHDR);
if (0 == pNMLV->iSubItem)
{
int cnt = m_list1.GetItemCount();
for (int i=0; i<cnt; i++)
{
m_list1.SetItemData(i,i);
}
m_list1.SortItems(SortData1,DWORD(this));

if (m_nSortSign1 >=0)
{
m_nSortSign1 = -1;
}
else
{
m_nSortSign1 = 1;
}
}

*pResult = 0;
}

方案二：对所有栏排序

系统函数

int CALLBACK SortData2(LPARAM lParam1, LPARAM lParam2, LPARAM lParamSort)
{
CListSortDlg* pDlg = (CListSortDlg*)lParamSort;
if (!pDlg)
{
return 0;
}

CListCtrl &list = (CListCtrl&)(pDlg->m_list2);

WORD wSubItem = (lParam1&0xFFFF0000)>>16;
WORD nItem1 = lParam1&0x0000FFFF;
WORD nItem2 = lParam2&0x0000FFFF;

CString sItem1 = list.GetItemText(nItem1,wSubItem);
CString sItem2 = list.GetItemText(nItem2,wSubItem);

if (sItem1 < sItem2)
{
return pDlg->m_nSortSign2;
}
else
{
return -1*pDlg->m_nSortSign2;
}

return 0;
}

排序事件

void CListSortDlg::OnColumnclickList2(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
// TODO: Add your control notification handler code here

LPNMLISTVIEW pNMLV = reinterpret_cast<LPNMLISTVIEW>(pNMHDR);
if (-1 < pNMLV->iSubItem)
{
DWORD dwItemData = 0;
int cnt = m_list2.GetItemCount();
for (int i=0; i<cnt; i++)
{
dwItemData = pNMLV->iSubItem;
dwItemData = dwItemData<<16;
dwItemData = dwItemData+i;
m_list2.SetItemData(i,dwItemData);
}
m_list2.SortItems(SortData2,DWORD(this));

if (m_nSortSign2 >=0)
{
m_nSortSign2 = -1;
}
else
{
m_nSortSign2 = 1;
}
}

*pResult = 0;
}

5.效果

运行程序



点击列表1标题栏，试试点击不同的栏的效果
