为 ttk.Button 指定颜色

Question

我想为按钮的背景和按钮的文本指定颜色。我以为我可以用 fg 和 bg 分配它，但在 ttk.Button.

中似乎根本没有引用

如何为我的按钮指定文本和背景颜色？

Python 文档解释了如何使用 ttk 更改颜色。这是一个简化的例子。

请注意根据用户交互改变颜色的样式图的使用。

import tkinter as tk
from tkinter import ttk

master = tk.Tk()

style = ttk.Style()
style.theme_use("default")

style.map("Mod.TButton",
          background = [("active", "red"), ("!active", "blue")],
          foreground = [("active", "yellow"), ("!active", "red")])

txt_btn = ttk.Button(master, text="Text", style="Mod.TButton").pack()

master.mainloop()

在您的代码中，您将 button1 映射到 style.map("work",，这应该是 style.map("work.TButton",。您的 button1 样式声明也需要相应更改。
