我尝试在面板右侧添加一个“变量”按钮，该按钮位于面板的上部，但是当我添加它时，在另一个面板向下的位置中，我总是发现缩放显示错误，如何通过保持右上方的面板与右下方的子面板之间的绑定来添加按钮
我尝试在右上角有2个子面板，一个用于按钮，另一个用于绘图，但是当我选择缩放以在子面板右下角对其进行绘图时，会给我错误：
self.GrandParent.right.bottom.top.right.Update(self.zoom_axes)
AttributeError: 'RightPanel' object has no attribute 'right'
当我遇到错误（Python 3.6）时，这就是代码的一部分：
