如何重置python tkinter按钮的背景颜色? [英] How to reset background color of a python tkinter button?

问题描述

简单的问题，解析了无数搜索结果，还没有找到简单的答案.如果找不到某些东西，我将一个非常紧急的按钮设置为红色，以便用户先单击它.单击后，我想像 button.config(bg='') 一样将背景设置回正常.我试过灰色"，但颜色不对.

Simple question, have parsed numerous search results, haven't found a simple answer. I set a very urgent button to red if something is not found so users click it first. Once clicked, I want to set the background back to normal like button.config(bg=''). I tried 'grey' but it's not the right color.

我将它设置为什么?

推荐答案

您可以在更改按钮之前询问它的颜色.保存颜色，稍后再恢复:

You can ask the button what color it is before you change it. Save the color, and then restore it later:

orig_color = the_button.cget("background")
the_button.configure(background="red")
...
the_button.configure(background=orig_color)
