VC控件——CTreeCtrl中HitTest的用法

 

用来获取鼠标当前位置，所在的Item句柄。

 

HTREEITEM  hItem;

const MSG* pMessage;

CPoint     pt;

UINT       nFlags;

pMessage = GetCurrentMessage();

ASSERT ( pMessage );

pt = pMessage->pt;

ScreenToClient( &pt );        

hItem = m_tree.HitTest( ptTree, &uFlags );

if ( ( hItem != NULL ) && ( uFlags & TVHT_ONITEM ) )

{

              // TODO：

}
