CListCtrl的用法总结

1 CListCtrl的风格

CListCtrl的风格有四种：

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

分别对应着资源管理器查看菜单下的大图标，小图标，列表，详细资料。

可以在控件属性视图下设置：View属性.

也可以用代码来设置，如下：

[cpp] view plaincopy print?

DWORD SetView(

int iView

);
DWORD SetView(int iView
);

以下解说均以report风格为例.

2 设置CListCtrl风格及扩展风格

获取及设置风格代码示例代码如下：

[cpp] view plaincopy print?

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

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

获取及设置扩展风格示例代码如下：

[cpp] view plaincopy print?

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

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

3 插入数据

插入列，示例代码如下：

[cpp] view plaincopy print?

m_list_av.InsertColumn(0,"PID");
m_list_av.InsertColumn(1,"name");
m_list_av.InsertColumn(2,"value");
CRect rect;
m_list_av.GetClientRect(rect); //获得当前客户区信息
m_list_av.SetColumnWidth(0,rect.Width()/6); //设置列的宽度。
m_list_av.SetColumnWidth(1,rect.Width()/2);
m_list_av.SetColumnWidth(2,rect.Width()/3);

m_list_av.InsertColumn(0,"PID");
m_list_av.InsertColumn(1,"name");
m_list_av.InsertColumn(2,"value");CRect rect;
m_list_av.GetClientRect(rect);                    //获得当前客户区信息
m_list_av.SetColumnWidth(0,rect.Width()/6);       //设置列的宽度。
m_list_av.SetColumnWidth(1,rect.Width()/2);
m_list_av.SetColumnWidth(2,rect.Width()/3);

也可用另一种方式，如：

[cpp] view plaincopy print?

m_list.InsertColumn( 0, "ID", LVCFMT_LEFT, 40 );//插入列，LVCFMT_LEFT为对齐方式，40为列宽
m_list.InsertColumn( 1, "NAME", LVCFMT_LEFT, 50 );

m_list.InsertColumn( 0, "ID", LVCFMT_LEFT, 40 );//插入列，LVCFMT_LEFT为对齐方式，40为列宽
m_list.InsertColumn( 1, "NAME", LVCFMT_LEFT, 50 );

插入行，示例代码如下：

[cpp] view plaincopy print?

CString str;
for(int i=0; i<m_av_count; i++){
m_list_av.InsertItem(i,m_avs[i].name);
str.Format("%04x",m_avs[i].pid);
m_list_av.SetItemText(i,0,str);
m_list_av.SetItemText(i,1,m_avs[i].name);
GetValueAsStirng(&m_avs[i],str);
m_list_av.SetItemText(i,2,str);
}

CString str;
for(int i=0; i<m_av_count; i++){m_list_av.InsertItem(i,m_avs[i].name);str.Format("%04x",m_avs[i].pid);m_list_av.SetItemText(i,0,str);m_list_av.SetItemText(i,1,m_avs[i].name);GetValueAsStirng(&m_avs[i],str);m_list_av.SetItemText(i,2,str);
}

另一个示例如下：

[cpp] view plaincopy print?

CString strText;
int nColumnCount = m_myListCtrl.GetHeaderCtrl()->GetItemCount();
// Insert 10 items in the list view control.
for (int i = 0; i < 10; i++)
{
strText.Format(TEXT("item %d"), i);
// Insert the item, select every other item.
m_myListCtrl.InsertItem(LVIF_TEXT | LVIF_STATE, i, strText,
(i % 2) == 0 ? LVIS_SELECTED : 0, LVIS_SELECTED, 0, 0);
// Initialize the text of the subitems.
for (int j = 1; j < nColumnCount; j++)
{
strText.Format(TEXT("sub-item %d %d"), i, j);
m_myListCtrl.SetItemText(i, j, strText);
}
}

CString strText;
int nColumnCount = m_myListCtrl.GetHeaderCtrl()->GetItemCount();// Insert 10 items in the list view control.
for (int i = 0; i < 10; i++)
{strText.Format(TEXT("item %d"), i);// Insert the item, select every other item.m_myListCtrl.InsertItem(LVIF_TEXT | LVIF_STATE, i, strText, (i % 2) == 0 ? LVIS_SELECTED : 0, LVIS_SELECTED, 0, 0);// Initialize the text of the subitems.for (int j = 1; j < nColumnCount; j++){strText.Format(TEXT("sub-item %d %d"), i, j);m_myListCtrl.SetItemText(i, j, strText);}
}

4 一直选中一行

在默认情况下，当选一行，再点击其它地方时，原先选中的一行会推动高亮显示，如果你想保留高亮显示，则可以在属性面板上找到属性Always Show Selection，并设置为true.

也可用设置扩展风格的方式设置，如：

[cpp] view plaincopy print?

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

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

5 选中和取消一行

[cpp] view plaincopy print?

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);

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);

另一种方式，包含获取选择项和设置：

[cpp] view plaincopy print?

// Set the selection mark to the first item only if no other item is
// selected.
if (m_myListCtrl.GetSelectionMark() == -1)
m_myListCtrl.SetSelectionMark(0);

// Set the selection mark to the first item only if no other item is
// selected.
if (m_myListCtrl.GetSelectionMark() == -1)m_myListCtrl.SetSelectionMark(0);

在单选时可用以上方法。

6 获取选择项

[cpp] view plaincopy print?

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);
}
}

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);}
}

另一种方法：

[cpp] view plaincopy print?

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
}
}

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}
}

获取单选项的示例代码:

[cpp] view plaincopy print?

POSITION pos =m_CLC_Record.GetFirstSelectedItemPosition();
if (pos == NULL)
{
AfxMessageBox("请先选择一项记录!");
return;
}
else
{
int nSel =m_CLC_Record.GetNextSelectedItem(pos);
//do something
}

POSITION pos =m_CLC_Record.GetFirstSelectedItemPosition();
if (pos == NULL)
{AfxMessageBox("请先选择一项记录!");return;
}
else
{int nSel =m_CLC_Record.GetNextSelectedItem(pos);//do something
}

7 绑定数据

[cpp] view plaincopy print?

// If any item's data is equal to zero then reset it to -1.
for (int i=0; i < m_myListCtrl.GetItemCount(); i++)
{
if (m_myListCtrl.GetItemData(i) == 0)
{
m_myListCtrl.SetItemData(i, (DWORD) -1);
}
}

// If any item's data is equal to zero then reset it to -1.
for (int i=0; i < m_myListCtrl.GetItemCount(); i++)
{if (m_myListCtrl.GetItemData(i) == 0){m_myListCtrl.SetItemData(i, (DWORD) -1);}
}

8 隐藏表头

有两种方法：

第一种：在属性面板中找到No Column Header属性，设置为true。

第二种：动态创建时使用LVS_NOCOLUMNHEADER。

9 获取总行数

[cpp] view plaincopy print?

int nCount =m_myListCtr.GetItemCount();

int nCount =m_myListCtr.GetItemCount();

10 滚屏

[cpp] view plaincopy print?

//滚屏
m_CLC_Record.EnsureVisible(nCount-1,false);

//滚屏
m_CLC_Record.EnsureVisible(nCount-1,false);

11 双击一行

为CListCtrl添加NM_DBLCK事件.

示例代码:

[cpp] view plaincopy print?

void CTestDlg::OnNMDblclkList1(NMHDR *pNMHDR, LRESULT *pResult)
{
LPNMITEMACTIVATE pNMItemActivate = reinterpret_cast<LPNMITEMACTIVATE>(pNMHDR);
// TODO: Add your control notification handler code here
NMLISTVIEW* pMListView=(NMLISTVIEW*) pNMHDR;
int nIndex = pMListView->iItem;
RecordData *pdata =(RecordData *)m_CLC_Record.GetItemData(nIndex);
m_ComboSendType.SetCurSel(pdata->SendFmt);
m_ComboSendFrmType.SetCurSel(pdata->FrameType);
m_ComboSendFrmFmt.SetCurSel(pdata->FramFmt);
m_EditSendFrmID.Format("%08x",pdata->FrameID);
m_EditSendData =m_CLC_Record.GetItemText(nIndex,4);
m_Delay =pdata->DelayTime;
UpdateData(false);
*pResult = 0;
}

void CTestDlg::OnNMDblclkList1(NMHDR *pNMHDR, LRESULT *pResult)
{LPNMITEMACTIVATE pNMItemActivate = reinterpret_cast<LPNMITEMACTIVATE>(pNMHDR);// TODO: Add your control notification handler code hereNMLISTVIEW* pMListView=(NMLISTVIEW*) pNMHDR;int nIndex = pMListView->iItem;RecordData *pdata =(RecordData *)m_CLC_Record.GetItemData(nIndex);m_ComboSendType.SetCurSel(pdata->SendFmt);m_ComboSendFrmType.SetCurSel(pdata->FrameType);m_ComboSendFrmFmt.SetCurSel(pdata->FramFmt);m_EditSendFrmID.Format("%08x",pdata->FrameID);m_EditSendData =m_CLC_Record.GetItemText(nIndex,4);m_Delay =pdata->DelayTime;UpdateData(false);*pResult = 0;
}

12 获取Item字符串

[cpp] view plaincopy print?

m_EditSendData =m_CLC_Record.GetItemText(nIndex,4);

m_EditSendData =m_CLC_Record.GetItemText(nIndex,4);
