python - 如何处理Python中另一个类的窗口小部件命令/函数调用？

当按下按钮时，我不想在该按钮所在的类中而是在另一个类中处理该函数调用。因此，以下是我要实现的代码：

class TestButton:
    def __init__(self, root):
        self.testButton = Button(root, text ="Test Button", command = testButtonPressed).grid(row = 11, column = 0)
        #testButtonPressed is called in the TestButton class.

class TestClass:

    #The testButtonPressed function is handled in the TestClass.
    def testButtonPressed():
        print "Button is pressed!"

请让我知道这是如何实现的，非常感谢！

注意：我编辑了回复，因为我无法正确理解您的问题。

在python中，您可以将函数作为参数传递：

class TestButton:
    def __init__(self, root, command):
        self.testButton = Button(root, text ="Test Button", command = command).grid(row = 11, column = 0)
        #testButtonPressed is called in the TestButton class.


class TestClass:

    #The testButtonPressed function is handled in the TestClass.
    def testButtonPressed(self):
        print "Button is pressed!"

TestButton(root, TestClass().testButtonPressed)
