How do I position a notification (tray) icon context menu on Windows XP?

Question

I'm using C++ and Win32.

I want my context menu and settings dialog to show up near the tray icon. I think I need the icon's coordinates to do that.

Shell_NotifyIconGetRect wasn't available until Windows 7.

WM_CONTEXTMENU is available starting in Win2k, but only provides coordinates in wParam as of Vista (and when specifying NOTIFYICON_VERSION_4).

Answer 1

Retrieving the click coordinates with GetCursorPos works well:

// Inside WndProc's switch(message)...
case WM_APP_NOTIFYCALLBACK:
    switch (LOWORD(lParam))
    {
    case WM_CONTEXTMENU: // XP and later
        {
            POINT pt = {};
            if( GetCursorPos(&pt) )
                ShowContextMenu(hWnd, pt, iStatus);
        }
        break;
    // ...
    }
    // ...
