C++ CListCtrl使用技巧的摘抄
转:http://blog.csdn.net/sanshao27/article/details/1888315
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_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;
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;
}

处理 NM_CUSTOMDRAW
http://www.codeproject.com/listctrl/lvcustomdraw.asp
另外介绍了一下五个小技巧:
1.让List
Control有Check Box
2.让List Box有Check Box
3.Spin
Control与Edit
Control的绑定
4.可以设置背景和文字颜色的Static控件
5.在Static控件中显示BMP
1.让List Control有Check
Box
用SetExtendedStyle方法可以设置,看代码:
(CListCtrl m_ListCtrl;)
DWORD
dwStyle = m_ListCtrl.GetStyle();
dwStyle |=
LVS_EX_CHECKBOXES;
m_ListCtrl.SetExtendedStyle(dwStyle);
2.让List
Box有Check Box
首先,声明Control变量的时候用CCheckListBox代替CListBox。
然后,将List
Box的Has Strings属性改为True;把Ower Draw属性改为Fixed。
3.Spin Control与Edit
Control的绑定
首先,要让Spin Control的Tap Order紧跟着Edit Control(就是说,Spin
Control的Tap Order是Edit Control的Tap Order加1)。
然后,设置Spin Control的Auto Buddy和Set
Buddy
Integer属性为True。
4.可以设置背景和文字颜色的Static控件
从CStatic类继承一个自己的Static类,相应WM_CTLCOLOR消息。下面是代码:
.h文件:
class
ClxStatic : public CStatic
{
DECLARE_DYNAMIC(ClxStatic)
public:
ClxStatic();
virtual
~ClxStatic();
afx_msg HBRUSH CtlColor(CDC* /*pDC*/, UINT
/*nCtlColor*/);
void SetBackColor(COLORREF
clrBack);
void SetTextColor(COLORREF
clrText);
protected:
DECLARE_MESSAGE_MAP()
CBrush
m_brushBack;
COLORREF m_clrBack;
COLORREF m_clrText;
};
.cpp文件:
IMPLEMENT_DYNAMIC(ClxStatic,
CStatic)
ClxStatic::ClxStatic()
{
m_clrBack =
::GetSysColor(COLOR_BTNFACE);
m_clrText =
::GetSysColor(COLOR_BTNTEXT);
}
ClxStatic::~ClxStatic()
{
}
void
ClxStatic::SetBackColor(COLORREF clrBack)
{
m_clrBack =
clrBack;
}
void ClxStatic::SetTextColor(COLORREF
clrText)
{
m_clrText =
clrText;
}
BEGIN_MESSAGE_MAP(ClxStatic, CStatic)
ON_WM_CTLCOLOR_REFLECT()
END_MESSAGE_MAP()
HBRUSH ClxStatic::CtlColor(CDC*
pDC, UINT /*nCtlColor*/)
{
//
TODO: Change any attributes of the DC here
m_brushBack.Detach();
m_brushBack.CreateSolidBrush(m_clrBack);
pDC->SetBkColor(m_clrBack);
pDC->SetTextColor(m_clrText);
//
TODO: Return a non-NULL brush if the parent‘s handler should not be
called
//return NULL;
return
(HBRUSH)m_brushBack.GetSafeHandle();
}
5.在Static控件中显示BMP
首先,给Static控件添加一个Control变量(ID要改了以后才能添加变量,也就是说ID不能为IDC_STATIC),本例为m_staticTest。
然后,用ModifyStyle函数修改Static控件的Style,让它可以显示图片:
m_staticTest.ModifyStyle(0,
SS_BITMAP | SS_CENTERIMAGE);
最后,就是Load文件显示出来:
CRect
rect;
m_staticTest.GetWindowRect(&rect);
//
下面的方法是按照Static控件的大小显示bmp,如果要安装图片实际大小显示,用这个方法Load图片:
// HBITMAP hBmp =
(HBITMAP)::LoadImage(0, _T("D://test.bmp"), IMAGE_BITMAP, 0, 0,
LR_LOADFROMFILE);
HBITMAP hBmp = (HBITMAP)::LoadImage(0,
_T("D://test.bmp"), IMAGE_BITMAP, rect.Width(), rect.Height(),
LR_LOADFROMFILE);
m_staticTest.SetBitmap(hBmp);
DeleteObject(hBmp);
