I have been investigating how to extend the Phone Canvas for video telephony.
Using AKU sample code I have extended the SK2 menu on the phone dialogs with
no problem. My problem occurs when I try to extend the SK2 menu on CProg. In
this case, I need to add 5+ menu items to a menu that already has 8 items.
On a 220x176 Smart phone (all work is being done on DeviceEmulator using
FakeRil), there are 2 choices:
1. Add the 5+ items to the SK2 menu and use the default action of a single
level scrolling menu. This technique does not seem to be the 'way to go'.
2. Add the new items as a single pop up menu which would cascade. This is
the technique that is used in Contacts so I thought this would be the 'way to
go'. When you scroll to the new menu item and select it, rather than the
expected pop up menu displaying, the original SK2 Menu appears as shown in
the right image. My guess is that either:
a. I am doing something wrong in my code or there is a bug in Crossbow. The
key method in my code is the QueryContextMenu method as shown below (which I
adopted from sample code in the Crossbow AKU build 15342).
b. There is a bug in Crossbow with the extension of the Phone Canvas and it
is not retaining the handle to the pop up menu inserted.
virtual HRESULT STDMETHODCALLTYPE QueryContextMenu(
HMENU hmenu,
UINT indexMenu,
UINT idCmdFirst,
UINT idCmdLast,
UINT uFlags
)
{
HRESULT hr = S_OK;
m_idc1 = idCmdFirst;
m_idc2 = idCmdFirst + 1;
m_idc3 = idCmdFirst + 2;
m_idc4 = idCmdFirst + 3;
m_idc5 = idCmdFirst + 4;
ASSERT(m_idc5 <= idCmdLast);
TCHAR szItemName[20];
TCHAR szMenuName[] = TEXT("Video");
hmenuPop = CreatePopupMenu();
if (hmenuPop == NULL)
{
hr = E_FAIL;
goto Error;
}
hr = GetItemName(m_idc1, szItemName,
(sizeof(szItemName)/sizeof(szItemName[0])));
// Insert Menu 1
if (!InsertMenu(hmenuPop, 0xFFFFFFFF, MF_BYPOSITION | MF_STRING,
m_idc1, szItemName))
{
hr = E_FAIL;
goto Error;
}
hr = GetItemName(m_idc2, szItemName,
(sizeof(szItemName)/sizeof(szItemName[0])));
// Insert Menu 2
if (!InsertMenu(hmenuPop, 0xFFFFFFFF, MF_BYPOSITION | MF_STRING,
m_idc2, szItemName))
{
hr = E_FAIL;
goto Error;
}
hr = GetItemName(m_idc3, szItemName,
(sizeof(szItemName)/sizeof(szItemName[0])));
// Insert Menu 3
if (!InsertMenu(hmenuPop, 0xFFFFFFFF, MF_BYPOSITION | MF_STRING,
m_idc3, szItemName))
{
hr = E_FAIL;
goto Error;
}
hr = GetItemName(m_idc4, szItemName,
(sizeof(szItemName)/sizeof(szItemName[0])));
// Insert Menu 4
if (!InsertMenu(hmenuPop, 0xFFFFFFFF, MF_BYPOSITION | MF_STRING,
m_idc4, szItemName))
{
hr = E_FAIL;
goto Error;
}
hr = GetItemName(m_idc5, szItemName,
(sizeof(szItemName)/sizeof(szItemName[0])));
// Insert Menu 5
if (!InsertMenu(hmenuPop, 0xFFFFFFFF, MF_BYPOSITION | MF_STRING,
m_idc5, szItemName))
{
hr = E_FAIL;
goto Error;
}
if (!InsertMenu(hmenu, indexMenu, MF_BYPOSITION | MF_STRING |
MF_POPUP, (UINT)hmenuPop, szMenuName))
{
hr = E_FAIL;
goto Error;
}
// Indicate that one popup with five items have been inserted
hr = MAKE_HRESULT(SEVERITY_SUCCESS, 0, 1);
Error:
return hr;
}
Can anyone offer me any help or advice?
Thanks in advance for any help or advice you can give me.
Best regards,

Firstly Crossbow hasn't been announced. Secondly if you are working for
an OEM on a device, then you or your company will have signed an
agreement saying you won't talk about WM device development in public
forums. With the agreement you should have been provided with official
channels to seek help through.
