python - Tkinter 单选按钮文本

Question

我有以下代码:

class Test:
    def __init__(self, master): # master is a Tk or Toplevel instance
        self.master, self.typeFrame = master, tk.Frame(master)
        self.typeVar = tk.StringVar(self.typeFrame)
        for column, wordType in enumerate(['Noun', 'Verb', 'Adjective', 'Adverb'], 1):
            typeRadioButton = tk.Radiobutton(self.typeFrame, text = wordType, textvariable = self.typeVar, value = wordType, command = self.createLambda(wordType))
            typeRadioButton.grid(row = 1, column = column)
        self.typeFrame.grid()

    def createLambda(self, obj):
        return lambda: self.changeInfo(obj)

    def changeInfo(self, obj):
        pass # this will do something later

但是，当我运行这样的代码时，单选按钮没有与之关联的文本。

root = tk.Tk()
test_instance = Test(root)
test_instance.master.mainloop()

我该如何解决这个问题？提前致谢!

Answer 1

将 textvariable=... 更改为 variable=...。

顺便说一句，您的示例不包含 self.typeFrame.pack() 或 self.typeFrame.grid(..)。
