[Interest] win: can't trap WM_ENTER/EXITMENULOOP?

[David M. Cotter]

in the documentation here 
<https://docs.microsoft.com/en-us/windows/win32/menurc/menus>, it indicates i 
can get a message when the menu bar starts to be browsed, and another when the 
browsing is completed.

this is exactly what i need (the purpose is unrelated to this post).

So in my QMainWindow derived class, i override the nativeEvent() method, like 
so:

bool    QBrowserWindow::nativeEvent(
        const QByteArray&       eventType,
        void                    *messageP,
        qintptr                 *resultP)
{
        bool            handledB(false);

        if (eventType == kWindowsEventType_GENERIC) {
                MSG&            msg(*(MSG *)messageP);

                switch (msg.message) {

                        default: {
                                //      nothing else
                        } break;

                        case WM_ENTERMENULOOP: {
                                Log("start menu browsing");
                                SuspendTableUpdates(true);
                        } break;

                        case WM_EXITMENULOOP: {
                                Log("end menu browsing");
                                SuspendTableUpdates(false);
                        } break;
                }
        }

        return handledB;
}
However, those messages are never sent :(

Any idea why not?
