python - 如何处理来自 Python 中另一个类的小部件命令/函数调用？

Question

按下按钮时，我想不在按钮所在的类中处理该函数调用，而是在另一个类中处理该函数调用。下面是我想要实现的目标的代码:

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!"

请告诉我这是如何实现的，非常感谢!

注意:我编辑了我的回复，因为我没有正确理解您的问题。

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)
