可用的：
一款类似于猎鸭的未完成软件游戏。表格有4行：开始和停止游戏，选择速度模式，结果，最底部有一个用于未来鸭子的QGraphic字段。当您按下按钮Начать игру时，会出现 8 个椭圆（鸭子），当您按下它们时，它们会消失。当您再次按下该按钮时，Начать игру旧的椭圆（鸭子）会被删除并出现新的椭圆。
问题：
您如何实现这些椭圆（鸭子）在整个字段上的“飞行”，以便所有其他功能（单击按钮、单击鸭子本身等）保持活动状态？可以使用setPos使用随机坐标的函数移动鸭子。如果你使用 function time.sleep()，那么整个程序就会挂起。
您能告诉我如何实施吗？我听说过一些关于溪流的事情，但对我来说这是一片黑森林。
代码：（所有动作都发生在类FormBuilder中，用于实现动作的函数用注释标记）
