右键菜单的单击行为如何触发

[woyaojinqu]

在列表框中创建了弹出右键菜单的功能，并使用classwizard创建了对应菜单项的消息映射函数，但无法触发，请问是什么原因呢？

添加以下函数
void Cxxxdlg::OnInitMenuPopup(CMenu* pPopupMenu, UINT nIndex, BOOL bSysMenu)
{
if (!bSysMenu)
{
ASSERT(pPopupMenu != NULL);

// check the enabled state of various menu items
CCmdUI state;
state.m_pMenu = pPopupMenu;
ASSERT(state.m_pOther == NULL);

state.m_nIndexMax = pPopupMenu->GetMenuItemCount();
for (state.m_nIndex = 0; state.m_nIndex < state.m_nIndexMax;
state.m_nIndex++)
{
state.m_nID = pPopupMenu->GetMenuItemID(state.m_nIndex);
if (state.m_nID == 0)
continue; // menu separator or invalid cmd - ignore it

ASSERT(state.m_pOther == NULL);
ASSERT(state.m_pMenu != NULL);
if (state.m_nID == (UINT)-1)
{
// possibly a popup menu, route to first item of that popup
state.m_pSubMenu = pPopupMenu->GetSubMenu(state.m_nIndex);
if (state.m_pSubMenu == NULL ||
(state.m_nID = state.m_pSubMenu->GetMenuItemID(0)) == 0 ||
state.m_nID == (UINT)-1)
{
continue; // first item of popup can't be routed to
}
state.DoUpdate(this, FALSE); // popups are never auto disabled
}
else
{
// normal menu item
// Auto enable/disable if command is _not_ a system command
state.m_pSubMenu = NULL;
state.DoUpdate(this, state.m_nID < 0xF000);
}
}
}
}

添加一个对应菜单的消息映射机制就可以了
在要使用右键菜单的类中添加如下部分
oncommand(菜单资源名，对应处理函数名（如可以是myfunc）)//添加到消息循环中
然后再定义myfunc函数就可以了
