I actually tryed to make a patch in QtnOfficeFrameHelper_win.cpp

I swapped the two lines:

if (msg->message == WM_NCHITTEST)
{
if (m_hwndFrame && msg->hwnd != m_hwndFrame && (m_ribbonBar && m_ribbonBar->testAttribute(Qt::WA_NativeWindow) && msg->hwnd == (HWND)m_ribbonBar->winId()))
{

because else during the winID() creation phase this snippet will call again winId() and resulting in an infinite recursion. By replacing with the code above, the winId() function is created only during the correct message manipulation (and also should be a little more performing)
But, even with this code there are other issues, for instance the title bar does not move when clicked. Surely they will need to enable explicit 5.10 support.

This code will be completely rewritten in QtitanRibbon 5. In the very near future, i will give you an answer what can be done to make this work in QtitanRibbon 4.
