推荐答案
如@shmicah所述，菜单环不支持动态设置bgcolor.但是，可以先创建一个文本环，然后将其替换为菜单环(右键单击->替换)，以解决"此问题.有趣的是，此方法适用于现代"和银色"菜单环，但不适用于经典菜单.
As explained by @shmicah, menu rings do not support dynamically setting of bgcolor. However, this can be "solved" by first creating a text ring and then replacing it (right click -> replace) with a menu ring. Interestingly, this method works for the "modern" and "silver" menu rings but not for the classic.
将文本环替换为菜单环后，原始代码按原样工作.
After replacing the text ring with a menu ring, the original code works as-is.
