[Development] Is QImage movable

[Иван Комиссаров]

Hi.

I’ve created a QVector of QImages and tried to insert an image in the vector:
QVector<QImage> images;
images.insert(images.begin(), QImage());

I got a compiler warning saying

"qvector.h:649:21: warning: destination for this 'memmove' call is a pointer to dynamic class 'QImage'; vtable pointer will be overwritten [-Wdynamic-class-memaccess]»

This happens because QImage inherits QPaintDevice (which is virtual) and QImage is declared movable using Q_DECLARE_SHARED macro.

Is this behavior intended?
