我正在Tkinter GUI中使用模块ScrolledText

我希望更改ScrolledText小部件中包含的滚动条的颜色，但我遇到了一些困难

根据文档，我的语法是正确的

Box = ScrolledText(root)
Box.vbar.config(troughcolor = 'red', bg = 'blue')
Box.pack()

但是，滚动条仍为标准灰色

我知道语法是正确的，因为做其他事情，例如：

 Box.vbar.config(cursor = 'target')

…工作完全正常

但是，尝试更改浮雕、边框宽度或颜色似乎没有任何效果。为什么会这样

规格：

Tk Scrollbar小部件vbar是Windows中的本机滚动条。其外观取决于Windows主题。如果有问题，考虑切换工具包；我知道PyQt4将允许您在Windows上设置滚动条的样式。

Tk scrollbar小部件vbar是Windows中的本机滚动条。其外观取决于Windows主题。如果有问题，考虑切换工具包；我知道PyQt4可以让您在Windows上设置滚动条的样式。

从我所读到的内容来看，在Windows上设置滚动条的格式非常困难。下面是我编写的滚动条程序的一些代码。我正在尝试开发一些应该有这些选项的软件，但在我看来，这就像是一个小部件的许多代码，其主要目的是Tkinter做得更好。但是，该程序应允许您将图像插入箭头、槽和滑块，以及更改其颜色
