Migrating to qt5 QGraphicsItem problem

Anticross

I've got existing code with class based on abstract class which inhreits QGraphicsObject. In that class I call scale method with two parameters and setAcceptsHoverEvents method. When i change my qt 4.8.4 to qt 5.0.1 i've got following errors in debugger:

@
1>src\GraphArc.cpp(14): error C3861: 'setAcceptsHoverEvents': identifier not found
1>src\GraphArc.cpp(16): error C3861: 'rotate': identifier not found
1>src\GraphArc.cpp(17): error C2660: 'QGraphicsItem::scale' : function does not take 2 arguments
@
I also instaled qt5vs addin and convert project from qmake to qtaddin project and hit widgets chebox in Qt Modules.

I am sure you found it, but in case someone else (like myself) runs into the problem of not finding setAcceptsHoverEvents(), the function has been deprecated, the new function is: setAcceptHoverEvents(). The simply dropped the s on Accept!

Also, rotate() was deprecated and changed to setRotation()

qreal QGraphicsItem::scale() const

This function was introduced in Qt 4.6.

No sign QGraphicsItem::scale ever accepted 2 arguments, unless maybe before 4.6. Which Qt version are you migrating from?
