内容:
QCanvasPolygon* tempPog = new QCanvasPolygon( canvas() );
QPointArray p_array(4);
p_array.setPoint(0,121,121);
p_array.setPoint(1,121,121);
p_array.setPoint(2,121,121);
p_array.setPoint(3,121,121);
tempPog->setPoints( p_array );
QCanvasItemList l = tempPog->collisions( false );
执行到tempPog->collisions( false );句出现空指针异常，不知所措
谢谢各位
