如何检测鼠标是否被点击？

Question

我正在尝试使用Python编写一个简短的脚本，当鼠标被点击时，鼠标将重置到某个任意位置（目前是屏幕中央）。

我希望它能在后台运行，以便与其他应用程序一起使用（最可能是Chrome或某个Web浏览器）。我还希望用户可以按住某个按钮（例如CTRL），并且他们可以随意点击而不会导致位置重置。这样他们就可以关闭脚本而不感到沮丧。

我相信我知道如何做到这一点，但我不确定要使用哪个库。我希望它是跨平台的，或者至少在Windows和Mac上可用。

以下是我目前的代码：

#! python3
# resetMouse.py - resets mouse on click - usuful for students with
# cognitive disabilities.

import pymouse

width, height = m.screen_size()
midWidth = (width + 1) / 2
midHeight = (height + 1) / 2

m = PyMouse()
k = PyKeyboard()


def onClick():
    m.move(midWidth, midHeight)


try:
    while True:
        # if button is held down:
            # continue
        # onClick()
except KeyboardInterrupt:
    print('\nDone.')

试一试

from pynput.mouse import Listener


def on_move(x, y):
    print(x, y)


def on_click(x, y, button, pressed):
    print(x, y, button, pressed)


def on_scroll(x, y, dx, dy):
    print(x, y, dx, dy)


with Listener(on_move=on_move, on_click=on_click, on_scroll=on_scroll) as listener:
    listener.join()

以下代码对我非常有效。感谢Hasan的答案。

from pynput.mouse import Listener

def is_clicked(x, y, button, pressed):
    if pressed:
        print('Clicked ! ') #in your case, you can move it to some other pos
        return False # to stop the thread after click

with Listener(on_click=is_clicked) as listener:
    listener.join()

我能够只使用win32api使其工作。当单击任何窗口时，它都可以正常工作。

import win32api
import time

width = win32api.GetSystemMetrics(0)
height = win32api.GetSystemMetrics(1)
midWidth = int((width + 1) / 2)
midHeight = int((height + 1) / 2)

state_left = win32api.GetKeyState(0x01)  # Left button up = 0 or 1. Button down = -127 or -128
while True:
    a = win32api.GetKeyState(0x01)
    if a != state_left:  # Button state changed
        state_left = a
        print(a)
        if a < 0:
            print('Left Button Pressed')
        else:
            print('Left Button Released')
            win32api.SetCursorPos((midWidth, midHeight))
    time.sleep(0.001)

我能够使用pyHook和win32api使其在Windows上工作：

import win32api, pyHook, pythoncom

width = win32api.GetSystemMetrics(0)
height = win32api.GetSystemMetrics(1)
midWidth = (width + 1) / 2
midHeight = (height + 1) / 2 

def moveCursor(x, y):
    print('Moving mouse')
    win32api.SetCursorPos((x, y))

def onclick(event):
    print(event.Position)
    moveCursor(int(midWidth), int(midHeight))
    return True 

try:
    hm = pyHook.HookManager()
    hm.SubscribeMouseAllButtonsUp(onclick)
    hm.HookMouse()
    pythoncom.PumpMessages()
except KeyboardInterrupt:
    hm.UnhookMouse()
    print('\nDone.')
    exit()
