modify 'mousearea-example' to run with MANY MORE buttons
Browse files Browse the repository at this point in the history 
The example formerly supported only 'Qt::LeftButton'
and 'Qt::RightButton'. This enhancement shows that qml
can work with any of the buttons supported by Qt itself.
(The example reacts to ALL 27 possible Qt mouse buttons.)

Task-number: QTBUG-24132
