tabletEvent not getting called on Windows 10

  • Using Qt 5.15.1 with a Wacom Intuos 5 Touch, I'm not seeing tabletEvent getting called at all in my main window class derived from QMainWindow. In fact, if I put a breakpoint in my main window's ::event() method when looking for QEvent::TabletPress, I never get anything there, either. I have the Wacom tablet driver installed and it seems to work well with other applications, including pressure sensitivity; the documentation mentions wintab32.dll, which I have verified is present on my system. Is there something that could be interfering and preventing Qt from seeing the tablet?
