Windows MFC migration framework: qmfcapp::wineventFilter keypress deferring to toplevel obsolete?

In qmfcapp.cpp there is a block that deals with deferring key up/down events to the toplevel HWND. This prevents a Qt dialog's shortcuts from being activated (e. g. a Buddy Label "N&ame", pressing Alt-a). Instead qmfcapp will try to delegate to the toplevel which doesn't work. It seems to me this code is completely unnecessary. All Menu actions on native toplevel windows work as expected in in Qt.5, so maybe this can be thrown out?

{{if (widget) {
HWND parent = (HWND)widget->winId();
while(parent)

{ toplevel = parent; parent = GetParent(parent); }

HMENU menu = toplevel ? GetMenu(toplevel) : 0;
if (menu && GetFocus() == msg->hwnd) {
if (msg->message == WM_SYSKEYUP && msg->wParam == VK_MENU)

{ // activate menubar on Alt-up and move focus away SetFocus(toplevel); SendMessage(toplevel, msg->message, msg->wParam, msg->lParam); widget->setFocus(); recursion = false; return TRUE; }

else if (msg->message == WM_SYSKEYDOWN && msg->wParam != VK_MENU)

{ SendMessage(toplevel, msg->message, msg->wParam, msg->lParam); SendMessage(toplevel, WM_SYSKEYUP, VK_MENU, msg->lParam); recursion = false; return TRUE; }

}
}
}}

This is somewhat related to QTSOLBUG-183
