您的问题
我相信您遇到的问题是 Ttk Checkbutton 实际上不是一个绘制的小部件，而是一个图像。
如何发现？
如果有人查看 github 项目 ttkthemes 并查看 themes folder，然后转到 radiance folder（这是一个类似 UBUNTU 的主题），然后转到 to the folder inside that labelled "radiance"。
你会看到这样的东西：
我们看到一个充满“GIF”的文件夹，这些是图像文件，如果向下滚动并找到文件：
check-dc.gif (Disabled Deselected)
check-du.gif (Disabled Deselected)
check-nc.gif (Normal Selected)
check-nu.gif (Normal Deselected)
如果我们查看这些文件可以看到，这些都是检查按钮的所有不同可能状态。
在 windows 下，这些检查按钮看起来像这样（生成 with this code）：
如何包含自定义检查按钮？
可以在here 找到一篇关于此的精彩帖子，他们通过在画布上添加绿色和红色方块来创建自定义检查按钮，但如果有人想要制作与您想要的类似的东西怎么办。在哪里更改检查按钮的颜色。
如何更改默认检查按钮的边框颜色？
首先让我们将所有 Checkbutton 图像转换为 gif 格式，我已经为您完成了，可以从my Google Drive 或我的Gofile 下载。
您需要从我的 Google 云端硬盘中获取：
check-nc.gif (Normal Selected)
check-nu.gif (Normal Deselected)
因为您无需担心已停用的值，因为它们永远不会被聚焦。
现在让我们看看他们如何加载上述帖子中的图像：
on_image = tk.PhotoImage(width=48, height=24)
off_image = tk.PhotoImage(width=48, height=24)
on_image.put(("green",), to=(0, 0, 23,23))
off_image.put(("red",), to=(24, 0, 47, 23))
在这里他们创建了两个空白图像，它们是 48px X 24px，其中两个在左侧添加了一个绿色方块，另一个在右侧添加了一个。
我们的处理方法类似但略有不同，相反，我们将加载您下载的两个 gif 文件，然后我们将编写一个脚本来制作 4 个矩形，这些矩形将覆盖当前的灰色轮廓复选按钮。像这样：
import tkinter as tk
root = tk.Tk()
def edit_check(colour, image):
image.put((colour,), to=(0, 0, 1, 13)) # LEFT
image.put((colour,), to=(0, 0, 13, 1)) # TOP
image.put((colour,), to=(12, 0, 13, 13)) # RIGHT
image.put((colour,), to=(0, 12, 13, 13)) # BOTTOM
def focus_in(event):
print(event)
image = off_image if var1.get() == 0 else on_image
edit_check("red", image)
cb1.configure(image=image)
cb1.image = image
def focus_out(event):
print(event)
image = off_image if var1.get() == 0 else on_image
edit_check("black", image)
cb1.configure(image=image)
cb1.image = image
on_image = tk.PhotoImage(file="check-nc.gif") # Instead of creating a new image we open an existing one
off_image = tk.PhotoImage(file="check-nu.gif") # Instead of creating a new image we open an existing one
var1 = tk.IntVar(value=0)
cb1 = tk.Checkbutton(root, image=off_image, selectimage=on_image, indicatoron=False,
onvalue=1, offvalue=0, variable=var1, offrelief='sunken')
cb1.pack(padx=20, pady=10)
# THESE IF YOU WANT TRUE FOCUS
#cb1.bind("<FocusIn>", focus_in)
#cb1.bind("<FocusOut>", focus_out)
# THESE IF YOU WANT MOUSE OVER
cb1.bind("<Enter>", focus_in)
cb1.bind("<Leave>", focus_out)
root.mainloop()
使用面向对象编程改进代码
这对于您的用例来说是更好的系统（请注意，它不需要任何图像文件，因为文件保存为 base64 字符串）
