QGraphicsItem : touch manipulation, how to ?

[Jena43]

Hello everyone,

I would like to manipulate QGraphicsItems in a QGraphicsScene by touch manipulations (scale, move, rotate, inertia).
I searched but found nothing already implemented for this.

I'm sad that the flag "QGraphicsItem::ItemIsMovable":http://qt-project.org/doc/qt-4.8/qgraphicsitem.html#GraphicsItemFlag-enum is available only for mouse manipulation...

Any idea how to do this ?

Thanks.
Using Qt5.2.

Touch events go through mousePressEvent handlers on QWidgets unless you set a widget attribute to change that.

Look at Qt::WA_AcceptTouchEvents

"Documentation":http://qt-project.org/doc/qt-5/qt.html#WidgetAttribute-enum

First, sorry for late answer. In fact I knew that, but it didn't answered me, because I was trying to achieve these manipulations for each touchs (and not only the first one), and not only move manipulation. I was working on collaborative apps, where users must manipulate the QGraphicsItems independently.

I had a project changement, so I don't need this anymore, but if someone created some default QGraphicsItems with touch manipulation enabled, I'll be pleased to know !

If I do something like this in the future, I'll come post this here :)
