Program crashes when adding QGraphicsEllipseItem to the scene

[MongKong]

Hello !!
I'm making a Four In a Row kinda game and i have problem spawning circles. When i press space i create an ellipse but when i try to add the thing to the scene my program just crashes...

This is Player.cpp where an object ( circle ) is created.


This is Zeton.cpp


This are Player's and Zeton's header files
