[Qt-qml] QDeclarativeItem subclasses and mouse events

[Jan Ekholm]

Hi,

I was recommended to make a C++ QDeclarativeItem subclass for my game map 
tiles to get better performance. This worked well and the class was easy to 
implement, register and get to work. However, I can't seem to get mouse 
press/release events to work, whatever I do the events aren't relayed to my 
items. The methods I try are:

    virtual void mousePressEvent (QGraphicsSceneMouseEvent *event);
    virtual void mouseReleaseEvent (QGraphicsSceneMouseEvent *event);

I guess I can make a MouseArea per item as I had before with my pure QML 
solution, but it's not ideal. The items are not rectangles in shape and it's 
not possible to have custom shapes for MouseArea. 

I see that the shape() method is called for the correct C++ item, so 
apparently something checks wether the mouse was pressed inside the C++ item, 
but I never get any event.

Probably there's something trivial I'm missing here? I've looked through all 
the demos and examples, but none of the C++ items are interactive that I can 
see.

Any hints as to where my failure to grok stuff would be?

Kind regards,
    Jan Ekholm
