    Description

      If the QGraphicsProxyWidget have a child widget, the touch events are not propagated to the child. Instead the touch events are sent to the widget which then will ignore the touch events and Qt starts synthesizing the touch events to the mouse events which are propagated to the child.

      Steps to reproduce the issue:
      1. Run attached sample project

      Expected outcome:
      The widget's child received the touch events.

      Actual outcome:

      The widget's child does not receive touch events.
