how to act on Touch on QGraphicsView?

[planetLars]

Hi,

this might be an embarrassing question for a Nokia device developer but I couldn't find how one processes touches on a Touch Screen. I searched Google for qt touch * (* = I tried several words) and qt mouse events but all I found was that mouse events are not signal based. But how do I act on them?

QGraphicsView has a QGraphicsScene which has several Items. Reading their documentation, event handling is written about but all functions are virtual: I would have to subclass and implement myself.

I have a QGraphicsView put onto the default centralWidget with Qt Designer. Now, I want a certain method be executed when I touch the QGraphicsView (or one of its icons, I could do my own object touched finding algorithm).

What do I have to do?

Thank you already for pointers.

You will have to subclass QGraphicsView and implement as you already mentioned.
or add scene with items to view and work on the signals, events available for them.

I subclassed an Item class and implemented its mousePressEvent method. I hope this catches the touch screen presses too. This did seem to be the only way. Thank you!
