How are touch events propogated to QML Items

  • Background: We have an application that is designed to run on a large touchscreen. we have noticed that if multiple people are touching the screen at the same time, the touch events "stack up" until all the app is doing is processing (old) touch events and then eventually it will crash. My solution to this was to filter the touch events using an event filter, but I was hoping someone could enlighten me to how touch events are propagated inside of the app?
