单击CListCtrl中的CheckBox触发什么事件？该用哪个函数处理？

[kekeke]

有人知道吗？谢谢！~~

[prog_st]

LVN_ITEMCHANGED

[kekeke]

我要的是click的时候的。。不是changed的时候的。。呵呵~~~有其他的吗？

[XiangDong]

NM_CLICK
lpnmitem = (LPNMITEMACTIVATE) lParam

[XiangDong]

NM_CLICK
lpnmitem = (LPNMITEMACTIVATE) lParam

LVN_COLUMNCLICK


Notifies a list view control's parent window that a column was clicked. This notification message is sent in the form of a WM_NOTIFY message.

是Checkbox的click，不是Item的click....

呵呵~~~

NM_CLICK
lpnmitem = (LPNMITEMACTIVATE) lParam

这个怎么判断是checkbox的click呢？能详细点吗？

panda_w的方法好！

比如可以如下：
(mylistdlg.h)

afx_msg void OnItemchangedList(NMHDR* pNMHDR, LRESULT* pResult);

(mylistdlg.cpp)

ON_NOTIFY(LVN_ITEMCHANGED, IDC_MY_LIST, OnItemchangedList)

void Cmylistdlg::OnItemchangedList(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
*pResult = 0;

if (pNMListView->uOldState == 0 && pNMListView->uNewState == 0)
return; // No change

// Old check box state
BOOL bPrevState = (BOOL)(((pNMListView->uOldState &
LVIS_STATEIMAGEMASK)>>12)-1);

if (bPrevState < 0) // On startup there's no previous state
bPrevState = 0; // so assign as false (unchecked)

// New check box state
BOOL bChecked=(BOOL)(((pNMListView->uNewState & LVIS_STATEIMAGEMASK)>>12)-1);

if (bChecked < 0) // On non-checkbox notifications assume false
bChecked = 0;

if (bPrevState == bChecked) // No change in check box
return;

// Now bChecked holds the new check box state
// ... do your process
}
