如何更改Tkinter ScrolledText小部件的滚动条颜色? [英] How ro change a Tkinter ScrolledText widget's Scrollbar color?

问题描述

我正在Tkinter GUI中使用模块 ScrolledText .

I'm using the module ScrolledText in a Tkinter GUI.

我希望更改 ScrolledText 小部件中包含的 Scrollbar 的颜色，但是遇到了一些困难.

I wish to change the colour of the Scrollbar encompassed in the ScrolledText widget, but I'm having some difficulty.

我的语法正确(根据文档).

My syntax is correct (according to documentation).

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

但是，滚动条仍然具有标准的灰色.

However, the scrollbar still has the standard grey colour.

我知道语法是正确的，因为做了其他事情，例如:

I know the syntax is correct, because doing other things such as:

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

...完全可以正常工作.

...works exactly as it should.

但是，尝试更改救济， borderwidth 或颜色似乎没有任何效果.
为什么会这样?

However, attempting to change the relief, borderwidth or colors don't seem to have any effect.
Why is this happening?

推荐答案

Tk滚动条小部件(vbar)是Windows中的本机滚动条.它的外观取决于Windows主题.如果重要的话，请考虑使用交换工具包；我知道PyQt4可以让您在Windows上设置滚动条的样式.

The Tk Scrollbar widget (vbar) is a native scrollbar in Windows. Its appearance depends on the Windows theme. Consider switching toolkits if it matters; I know PyQt4 will let you style the scrollbar on Windows.
