If the widget interprets a mouse click, screen touch or a press on the
tablet as mouse events then there may not be a way to distinguish between
them. In other words, if Windows converts events to mouse clicks and sends
them to Qt then there wouldn't be a way to tell.

If you are receiving different kinds of events for the mouse, screen and
tablet then you could install event filters to stop certain kinds of events
from being delivered to each widget. Qt has classes to represent these
kinds of events:
So, in theory, it should be possible.
