从类实例获取属性而不传递Self

Question

from pynput.mouse import Listener, Button

class ClickListener:
    def __init__(self):
        self.ClickTimes = 0
        self.CurrentClick = 0
        self.ClickPositions = []

    def on_click(x, y, button, pressed):
        if pressed and button == Button.middle:
            ClickPositions.append((x,y))
            self.CurrentClick += 1
            if self.ClickTimes <= self.CurrentClick:
                return Falses

    def getClicks(self, nr):
        self.ClickPositions = []
        self.CurrentClick = 0
        self.ClickTimes = nr
        with Listener(on_click = ClickListener.on_click) as listener:
            listener.join()
        return self.ClickPositions

在函数'on_click'上，由于调用函数的事件是如何获得自我属性的？看来我无法将自我对象传递给事件。

Edit1。：

class ClickListener:
    def __init__(self):
        self.ClickTimes = 0
        self.CurrentClick = 0
        self.ClickPositions = []

    def on_click(self, x, y, button, pressed):
        if pressed and button == Button.middle:
            self.ClickPositions.append((x,y))
            self.CurrentClick += 1
            if self.ClickTimes <= self.CurrentClick:
                return Falses

    def getClicks(self, nr):
        self.ClickPositions = []
        self.CurrentClick = 0
        self.ClickTimes = nr
        with Listener(on_click = self.on_click) as listener:
            listener.join()
        return self.ClickPositions

在这种情况下，它说缺少一个必需的参数，即“按下”的参数。

您可以使用类似这样的东西。

from pynput.mouse import Listener, Button

class ClickListener:
    def __init__(self):
        self.ClickTimes = 0
        self.CurrentClick = 0
        self.ClickPositions = []

    @classmethod
    def on_click(cls, x, y, button, pressed):
        if pressed and button == Button.middle:
            cls.ClickPositions.append((x,y))
            cls.CurrentClick += 1
            if cls.ClickTimes <= cls.CurrentClick:
                return Falses

    @classmethod
    def getClicks(cls, nr):
       cls.ClickPositions = []
       cls.CurrentClick = 0
       cls.ClickTimes = nr
       with Listener(on_click = cls.on_click) as listener:
            listener.join()
       return cls.ClickPositions

将“自身”作为“ on_click”函数中的第一个参数传递。

from pynput.mouse import Listener, Button

class ClickListener:
    def __init__(self):
        self.ClickTimes = 0
        self.CurrentClick = 0
        self.ClickPositions = []

    def on_click(self, x, y, button, pressed):
        if pressed and button == Button.middle:
            ClickPositions.append((x,y))
            self.CurrentClick += 1
            if self.ClickTimes <= self.CurrentClick:
                return Falses

    def getClicks(self, nr):
       self.ClickPositions = []
       self.CurrentClick = 0
       self.ClickTimes = nr
       with Listener(on_click = ClickListener.on_click) as listener:
            listener.join()
       return self.ClickPositions
