CListCtrl控件使用方法总结 (转)
以下未经说明,listctrl默认view 风格为report
相关类及处理函数
MFC:CListCtrl类
SDK:以 “ListView_”开头的一些宏。如 ListView_InsertColumn
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
);
int nRow = m_list.InsertItem(0, “11”);//插入行
m_list.SetItemText(nRow, 1, “jacky”);//设置数据
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_SHOWSELALWAYS5. 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; i<m_list.GetItemCount(); i++)
{
if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED ||
m_list.GetCheck(i))
{
str.Format(_T("第%d行的checkbox为选中状态"), i);
AfxMessageBox(str);
}
}
7. 得到listctrl中所有选中行的序号
方法一:
CString
str;
for(int i=0; i<m_list.GetItemCount(); i++)
{
if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED
)
{
str.Format(_T("选中了第%d行"),
i);
AfxMessageBox(str);
}
}
方法二:
POSITION pos =
m_list.GetFirstSelectedItemPosition();
if (pos == NULL)
TRACE0("No items were selected!\n");
else
{
while (pos)
{
int nItem =
m_list.GetNextSelectedItem(pos);
TRACE1("Item %d was
selected!\n", nItem);
// you could do your own processing on
nItem here
}
}
8. 得到item的信息
TCHAR szBuf[1024];
LVITEM lvi;
lvi.iItem =
nItemIndex;
lvi.iSubItem = 0;
lvi.mask = LVIF_TEXT;
lvi.pszText = szBuf;
lvi.cchTextMax = 1024;
m_list.GetItem(&lvi);
关于得到设置item的状态,还可以参考msdn文章
Q173242: Use Masks to Set/Get Item
States in CListCtrl
http://support.microsoft.com/kb/173242/en-us
9. 得到listctrl的所有列的header字符串内容
LVCOLUMN lvcol;
char str[256];
int
nColNum;
CString strColumnName[4];//假如有4列
nColNum = 0;
lvcol.mask = LVCF_TEXT;
lvcol.pszText =
str;
lvcol.cchTextMax = 256;
while(m_list.GetColumn(nColNum,
&lvcol))
{
strColumnName[nColNum] =
lvcol.pszText;
nColNum++;
}
10. 使listctrl中一项可见,即滚动滚动条
m_list.EnsureVisible(i, FALSE);11. 得到listctrl列数
int nHeadNum = m_list.GetHeaderCtrl()->GetItemCount();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);
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;
}
17.
改变选中行的颜色
首先是添加以下消息
ON_NOTIFY( NM_CUSTOMDRAW, IDC_LIST1, OnDrawColorForMyList ) //为改变颜色添加的消息
再添加类成员函数,就OK了:
