右键菜单问题?

[hefeng]

我有一个从CTreeView派生的view类,想实现按右键弹出一个菜单,可不知为什么按一下不行,非要按两下才能出来菜单,请指教.

void CMyTreeView::showPopupMenu(CPoint& point)
{
if (point.x == -1 && point.y == -1){
//keystroke invocation
CRect rect;
GetClientRect(rect);
ClientToScreen(rect);

point = rect.TopLeft();
point.Offset(5, 5);
}

CMenu menu;
VERIFY(menu.LoadMenu(IDR_MENU_CONTEXT));

CMenu* pPopup = menu.GetSubMenu(0);
ASSERT(pPopup != NULL);
CWnd* pWndPopupOwner = this;

while (pWndPopupOwner->GetStyle() & WS_CHILD)
pWndPopupOwner = pWndPopupOwner->GetParent();

pPopup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y,
pWndPopupOwner);
}

直接在WM_CONTEXTMENU消息映射函数中处理就可以了
void CMyTreeView::OnContextMenu(CWnd *pWnd,CPoint point)
{.....}

我是在WM_CONTEXTMENU消息映射函数中处理的,然后调用showPopupMenu.

在showPopupMenu(CPoint& point)当中加入一个消息框
看看弹击一下右键的话是不是执行了这个函数????

在TrackPopupMenu前
需要先调用SetForegroundWindos()

还是不行啊！！！
