Hi,
I am trying to implement and test a simple drag and drop scenario using drag and drop within the context of QGraphicsView/QGraphicsScene. I am using the 40000 Chips example from Qt as a starting point. I am simply trying to implement drag on drop when a chip is dragged in one of the views. I added the following to GraphicsView (implementation of QDragMoveEvent):
class GraphicsView : public QGraphicsView
{
Q_OBJECT
public:
GraphicsView(View *v) : QGraphicsView(), view(v) { }
protected:
#ifndef QT_NO_WHEELEVENT
void wheelEvent(QWheelEvent *);
#endif
private:
View *view;
protected:
virtual void dragMoveEvent(QDragMoveEvent * event);
};
void View::dragMoveEvent(QGraphicsSceneDragDropEvent *event)
{
qDebug() << “In dragMoveEvent”;
}
However, when I drag a chip around inside a view, I am not seeing that dragMoveEvent is being called. What am I doing wrong here? Shouldn’t this method be called when chips are dragged within a view?
Thanks.
-Jon
