如何删除 Tkinter OptionMenu 小部件的边框

Question

我浏览了多个网站，只给了我一半满意的答案，我将如何为 Tkinter OptionMenu Widget 的每个部分着色？

代码片段：

from tkinter import *

root = Tk()
text = StringVar()

fr = Frame (root,bg="yellow")
fr.grid()

menu = OptionMenu (fr, text, "hi", "there")
menu.grid (pady=50, padx=50)

# Pretty colouring goes here
# Or ugly yellow, I don't mind

menu ["menu"] ["bg"] = "yellow"
menu ["bg"] = "yellow"
menu ["activebackground"] = "green"

root.mainloop()

还是我应该放弃并满足于灰色？

Answer 1

我所要做的就是将highlightthickness选项设置为0

menu["highlightthickness"]=0

这摆脱了下拉菜单周围的丑陋边框。
