python-3.x - 如何从在 Python tkinter 中生成按钮的 Scale/Slider 获取值

Question

我有一个按钮，单击时会显示滑块/比例。如何从滑块中获取选定的值？我的代码返回错误：“TypeError: funcSlider() missing 1 required positional argument: 'value'”

self.list = {}

    def onClick(self):
        print (self.list)
        return
    def funcSlider(self, posX,posY,key,value):
        w = tk.Scale(self, from_=0, to=8, orient='horizontal')
        w.pack()
        w.place(x=posX, y=posY, in_=self)
        self.list [key] = value

button = tk.Button(self, text="button ",
                   command=lambda: self.funcSlider(120,33,'test'),width = 20)
button .pack(anchor="w")
button .place(x=250, y=50, in_=self)

button2 = tk.Button(self, text="Send",
                        command=self.onClick, width=42,bg="#4BAD2E")
button2 .pack(anchor="w")
button2 .place(x=250, y=430, in_=self)

我想我做到了。我不知道这是否是一个“好习惯”，但它有效：D

self.list = {}

    def foo(self,x,key):
        self.list [key] = x
    def onClick(self):
        print (self.list)
        return
    def funcSlider(self, posX,posY,key):
        w = tk.Scale(self, from_=0, to=8, orient='horizontal',command=lambda s: self.foo(s,key))
        w.pack()
        w.place(x=posX, y=posY, in_=self)
        self.list [key] = value

button = tk.Button(self, text="button ",
                   command=lambda: self.funcSlider(120,33,'test'),width = 20)
button .pack(anchor="w")
button .place(x=250, y=50, in_=self)

button2 = tk.Button(self, text="Send",
                        command=self.onClick, width=42,bg="#4BAD2E")
button2 .pack(anchor="w")
button2 .place(x=250, y=430, in_=self)
