CListCtrl 使用技巧

CListCtrl 使用技巧

1. CListCtrl 风格

2. 设置listctrl 风格及扩展风格

3. 插入数据

4. 一直选中item

5. 选中和取消选中一行

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

{

if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED || m_list.Get Check(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

{

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

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;

https://www.360docs.net/doc/b78088321.html,hTextMax = 256;

while(m_list.GetColumn(nColNum, &lvcol))

10. 使listctrl中一项可见，即滚动滚动条

11. 得到listctrl列数

12. 删除所有列

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",

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");

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)

17. 得到另一个进程里的listctrl控件的item内容

18. 选中listview中的item

19. 如何在CListView中使用CListCtrl的派生类

20. listctrl的subitem添加图标

21. 在CListCtrl显示文件，并根据文件类型来显示图标
