    Description

      On Windows, while a shift key pressed, you don't get a keyPressEvent when you press the second shift key of the keyboard.
      It is the case in qml and qt gui widget.

      Btw, the behaviour is similar for the ctrl keys: if you press the left one, and while it is pressed, you press the right one, you don't have a keyPressEvent for the second. However, while both are pressed, if you release the first one key, you have the keyPressEvent for the second.

      The problem does not exist on linux (you get 2 events).

      The aim of pressing both keys at the same time is for an educational activity (GCompris).

      Attached, there are the 2 versions (qt quick and qt gui).
