有没有办法让 tkinter Radiobutton 在 tkinter 画布上透明？

如何解决有没有办法让 tkinter Radiobutton 在 tkinter 画布上透明？

我想让单选按钮在画布图像上透明以使其看起来不错，我尝试将许多选项参数传递给单选按钮以某种方式使其看起来更好但没有任何效果。

这是我正在使用的代码...

from tkinter import *
from tkinter import ttk
from tkinter.ttk import *
from PIL import ImageTk,Image
from tkinter import messageBox 


class GUI_Prog:
    def __init__(self):
            root = Tk()
            root.title("Risk Analysis")
            root.geometry("1100x630")
            r = Intvar()

            #Setting up Canvas :
            my_canvas = Canvas(root,width=1100,height=630)
            my_canvas.pack(fill="both",expand=True)

            #Background :
            img = Image.open("diagnosis.png")
            img = img.resize((1100,630),Image.ANTIALIAS)
            bg =  ImageTk.PhotoImage(img)
            my_canvas.create_image(0,image=bg,anchor="nw")

            #Creating title text :
            my_canvas.create_text(540,40,text="Risk Analysis",font=("Times,30"),fill = "white")
            my_canvas.create_text(140,100,text="1) Do you smoke?",font=("helvetica,15"),fill = "black")

            but_1 = Radiobutton(root,text="yes",variable=r,value=1)
            my_canvas.create_window(60,150,window=but_1)

            but_2= Radiobutton(root,text="no",value=2)
            my_canvas.create_window(150,window=but_2)

            mainloop()


obj = GUI_Prog()

解决方法

好吧，我创建了自己的 RadioButton 类，但它仅适用于 tkinter.Canvas：

from tkinter import *
from tkinter import ttk
from tkinter.ttk import *
from PIL import ImageTk,Image
from tkinter import messagebox

            but_1.put(60,150)

            but_2 = Radiobutton(my_canvas,text="no",value=2,fill="white")
            but_2.put(150,150)

            r.set(1)

            root.mainloop()


obj = GUI_Prog()

您可以正常创建它，但将 <tkinter.Canvas> 作为其 master 传入。之后，您只需使用您希望创建它的位置调用 .put。这是一个非常不完整的解决方案，所以如果其他人发布了更好的解决方案，我会删除它。
