paintEvent() missing 1 required positional argument

错误"paintEvent() missing 1 required positional argument"可能是由于在调用paintEvent方法时缺少了一个必需的位置参数。根据引用中的解释，对于方法调用，对象会作为函数的第一个参数传递。因此，在调用paintEvent方法时，可能需要传递一个参数才能满足方法定义的要求。你可以检查一下在调用paintEvent方法时是否缺少了必要的参数。另外，根据引用的建议，你可以删除Button的command参数中的event，这样可能可以解决这个错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
