Привет, как создать маленький ректангл внутри другого большого ректангла (как из Qt/C++ - Lesson 023), чтобы этот маленький ректангл перемещался только вдоль краев большого и внтури него?

По идее нужно его сделать нарисовать следующим, он будет сверху. В маус эвенте прописать границы, и при выходе за них, оставлять картинку на последнем месте внутри границы.

    • The answer was marked as a solution.

    setParent - назначает родителя
    а флаг QGraphicsItem::ItemClipsChildrenToShape отвечает за прорисовку только в пределах контура setFlags(QGraphicsItem::ItemClipsChildrenToShape) установит его в true
