MFC List Control控件技巧总汇

转自：http://hi.baidu.com/qi_xian/blog/item/1971aa22da89ada24723e856.html

以下未经说明，listctrl默认view 风格为report

-------------------------------------------------------------------------------

1. CListCtrl 风格

LVS_ICON: 为每个item显示大图标

LVS_SMALLICON: 为每个item显示小图标

LVS_LIST: 显示一列带有小图标的item

LVS_REPORT: 显示item详细资料

直观的理解：windows资源管理器，"查看"标签下的"大图标，小图标，列表，详细资料

--------------------------------------------------------------------------------

2. 设置listctrl 风格及扩展风格

LONG lStyle;

lStyle = GetWindowLong(m_list.m_hWnd, GWL_STYLE);//获取当前窗口style

lStyle &= ~LVS_TYPEMASK; //清除显示方式位

lStyle |= LVS_REPORT; //设置style

SetWindowLong(m_list.m_hWnd, GWL_STYLE, lStyle);//设置style

DWORD dwStyle = m_list.GetExtendedStyle();

dwStyle |= LVS_EX_FULLROWSELECT;//选中某行使整行高亮（只适用与report风格的listctrl）

dwStyle |= LVS_EX_GRIDLINES;//网格线（只适用与report风格的listctrl）

dwStyle |= LVS_EX_CHECKBOXES;//item前生成checkbox控件

m_list.SetExtendedStyle(dwStyle); //设置扩展风格

注：listview的style请查阅msdn

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceshellui5/html/wce50lrflistviewstyles.asp

--------------------------------------------------------------------------------

3. 插入数据

m_list.InsertColumn( 0, "ID", LVCFMT_LEFT, 40 );//插入列

m_list.InsertColumn( 1, "NAME", LVCFMT_LEFT, 50 );

//新插入的在上面

int nRow = m_list.InsertItem(0, "11");// 插入行

m_list.SetItemText(nRow, 1, "jacky");//设置其它列数据

//新插入的数据在下面

int nIndex = m_list.GetItemCount();

LV_ITEM lvItem;

lvItem.mask = LVIF_TEXT ;

lvItem.iItem = nIndex; //行数

lvItem.iSubItem = 0;

lvItem.pszText = (char*)(LPCTSTR)strCount; //第一列

//在最后一行插入记录值.

m_list.InsertItem(&lvItem);

//插入其它列

m_list.SetItemText(nIndex,1,strLat);

--------------------------------------------------------------------------------

4. 一直选中item

选中style中的Show selection always，或者在上面第2点中设置LVS_SHOWSELALWAYS

--------------------------------------------------------------------------------

5. 选中和取消选中一行

int nIndex = 0;

//选中

m_list.SetItemState(nIndex, LVIS_SELECTED|LVIS_FOCUSED, LVIS_SELECTED|LVIS_FOCUSED);

//取消选中

m_list.SetItemState(nIndex, 0, LVIS_SELECTED|LVIS_FOCUSED);

--------------------------------------------------------------------------------

6. 得到listctrl中所有行的checkbox的状态

m_list.SetExtendedStyle(LVS_EX_CHECKBOXES);

CString str;

for(int i=0; iGetItemCount();

--------------------------------------------------------------------------------

12. 删除所有列

方法一：

while ( m_list.DeleteColumn (0))

因为你删除了第一列后，后面的列会依次向上移动。

方法二：

int nColumns = 4;

for (int i=nColumns-1; i>=0; i--)

m_list.DeleteColumn (i);

删除所有行

直接用第7点的方法得到所有选中的行号，然后用DeleteItem(i)想删除所有行，这样是行不通的。因为ListCtrl的行号是从上往下排列的，你删除了上面的行后，下面的行号也随之改变，所以用此方法无法删除所有行。正确的方法是从下往上删除行。如下所示：

for(int i=m_list.GetItemCount()-1; i>=0;i--)

{

if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED )

{

m_list.DeleteItem(i);

}

}

--------------------------------------------------------------------------------

13. 得到单击的listctrl的行列号

添加listctrl控件的NM_CLICK消息相应函数

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("单击的是第%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("单击的是第%d行第%d列",

pNMListView->iItem, pNMListView->iSubItem);

AfxMessageBox(strtemp);

}

*/

*pResult = 0;

}

--------------------------------------------------------------------------------

14. 判断是否点击在listctrl的checkbox上

添加listctrl控件的NM_CLICK消息相应函数

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);

//判断是否点在checkbox上

if(nFlag == LVHT_ONITEMSTATEICON)

{

AfxMessageBox("点在listctrl的checkbox上");

}

*pResult = 0;

}

--------------------------------------------------------------------------------

15. 右键点击listctrl的item弹出菜单

添加listctrl控件的NM_RCLICK消息相应函数

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切换焦点时(包括用键盘和鼠标切换item时)，状态的一些变化顺序

添加listctrl控件的LVN_ITEMCHANGED消息相应函数

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;

SHFILEINFO sfi;

char cSysDir[MAX_PATH];

CString strBuf;

memset(cSysDir, 0, MAX_PATH);

GetWindowsDirectory(cSysDir, MAX_PATH);

strBuf = cSysDir;

sprintf(cSysDir, "%s", strBuf.Left(strBuf.Find("//")+1));

himlSmall = (HIMAGELIST)SHGetFileInfo ((LPCSTR)cSysDir, 0, &sfi, sizeof(SHFILEINFO), SHGFI_SYSICONINDEX | SHGFI_SMALLICON );

himlLarge = (HIMAGELIST)SHGetFileInfo((LPCSTR)cSysDir, 0, &sfi, s izeof(SHFILEINFO), SHGFI_SYSICONINDEX | SHGFI_LARGEICON);

if (himlSmall && himlLarge)

{

::SendMessage(m_list.m_hWnd,LVM_SETIMAGELIST, (WPARAM)LVSIL_SMALL, (LPARAM)himlSmall);

::SendMessage(m_list.m_hWnd, LVM_SETIMAGELIST,

(WPARAM)LVSIL_NORMAL, (LPARAM)himlLarge);

}

return TRUE; // return TRUE unless you set the focus to a control

}

void CTest6Dlg::AddFiles(LPCTSTR lpszFileName, BOOL bAddToDocument)

{

int nIcon = GetIconIndex(lpszFileName, FALSE, FALSE);

CString strSize;

CFileFind filefind;

// get file size

if (filefind.FindFile(lpszFileName))

{

filefind.FindNextFile();

strSize.Format("%d", filefind.GetLength());

}

else

strSize = "0";

// split path and filename

CString strFileName = lpszFileName;

CString strPath;

int nPos = strFileName.ReverseFind('//');

if (nPos != -1)

{

strPath = strFileName.Left(nPos);

strFileName = strFileName.Mid(nPos + 1);

}

// insert to list

int nItem = m_list.GetItemCount();

m_list.InsertItem(nItem, strFileName, nIcon);

m_list.SetItemText(nItem, 1, strSize);

m_list.SetItemText(nItem, 2, strFileName.Right(3));

m_list.SetItemText(nItem, 3, strPath);

}

int CTest6Dlg::GetIconIndex(LPCTSTR lpszPath, BOOL bIsDir, BOOL bSelected)

{

SHFILEINFO sfi;

memset(&sfi, 0, sizeof(sfi));

if (bIsDir)

{

SHGetFileInfo(lpszPath,

FILE_ATTRIBUTE_DIRECTORY,

&sfi,

sizeof(sfi),

SHGFI_SMALLICON | SHGFI_SYSICONINDEX |

SHGFI_USEFILEATTRIBUTES |(bSelected ? SHGFI_OPENICON : 0));

return sfi.iIcon;

}

else

{

SHGetFileInfo (lpszPath,

FILE_ATTRIBUTE_NORMAL,

&sfi,

sizeof(sfi),

SHGFI_SMALLICON | SHGFI_SYSICONINDEX |

SHGFI_USEFILEATTRIBUTES | (bSelected ? SHGFI_OPENICON : 0));

return sfi.iIcon;

}

return -1;

}
