Yes...

I just tried this with grabMouse() / releaseMouse() and mouse-tracking... 
for me it simply works!

Just make sure to grab the mouse outside of your main-window's 
constructor.

--
MainWindow::MainWindow(QWidget *parent)
  : QMainWindow(parent)
{
  setupUi(this);

  // ...

  setMouseTracking(true);
  QTimer::singleShot(100, this, SLOT(delayedInit()));
}

MainWindow::~MainWindow()
{
  releaseMouse();
}

void MainWindow::delayedInit()
{
  grabMouse();
}
