CListCtrl 如何在鼠标移动消息OnMouseMove里获得当前鼠标下的子项索引?
就是鼠标下当前列的索引,不是行.
我在CListCtr 里添加了一个CComboBox,鼠标点击的时候就在子项的区域显示.我想在鼠标移动出这个区域后就隐藏CComboBox.
所以我想在OnMouseMove消息里判断鼠标是不是移出了这个区域.但HitTest()只能得到某一点的行索引,问下怎么才能得到某点的列索引?
搜资料也搜不到,如果计算像素感觉自已也不容易算准确,因为列可以拖动,
没办法,求助.

LVHITTESTINFO typedef struct _LVHITTESTINFO { POINT pt; UINT flags; int iItem; int iSubItem; } LVHITTESTINFO, FAR *LPLVHITTESTINFO; Has been extended to accommodate subitem hit-testing. The LVHITTESTINFO structure contains information about a hit test. It is used in association with the LVM_HITTEST and LVM_SUBITEMHITTEST messages and their related macros. This structure supersedes the LV_HITTESTINFO structure.

能说仔细一点吗?怎么填充这个结构? LVM_HITTEST and LVM_SUBITEMHITTEST在CListCtrl里怎么也找不到这2个消息?

#define LVM_SUBITEMHITTEST (LVM_FIRST + 57) #define ListView_SubItemHitTest(hwnd, plvhti) \ (int)SNDMSG((hwnd), LVM_SUBITEMHITTEST, 0, (LPARAM)(LPLVHITTESTINFO)(plvhti))

void CXListCtrl::OnMouseMove(UINT nFlags, CPoint point) 
{
	// TODO: Add your message handler code here and/or call default
	LVHITTESTINFO lvhitTestInfo;
	
	lvhitTestInfo.pt = point;
	
	int nItem = ListView_SubItemHitTest(this->m_hWnd, &lvhitTestInfo);
	int nSubItem = lvhitTestInfo.iSubItem;
	afxDump << nItem << ";" << nSubItem << "\n";
//
	CListCtrl::OnMouseMove(nFlags, point);
}

成员函数GetSubItemRect可以得到每个单元格所的矩形区域，可以判断鼠标坐标是否在某个区域里
