CListCtrl用法简介及使用技巧（二）

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;
}

20. listctrl的subitem添加图标

m_list.SetExtendedStyle(LVS_EX_SUBITEMIMAGES);
m_list.SetItem(..); //具体参数请参考msdn

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

21. 在CListCtrl显示文件，并根据文件类型来显示图标

网上找到的代码，share

BOOL CTest6Dlg::OnInitDialog()
{
CDialog::OnInitDialog();

HIMAGELIST himlSmall;
HIMAGELIST himlLarge;
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,
sizeof(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;
}

22. listctrl内容进行大数据量更新时，避免闪烁

m_list.SetRedraw(FALSE);
//更新内容
m_list.SetRedraw(TRUE);
m_list.Invalidate();
m_list.UpdateWindow();

或者参考
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_mfc_cwnd.3a3a.setredraw.asp
