python linux mouse event listener code example

Example 1: pynput mouse click

from pynput.mouse import Button, Controller

mouse = Controller()

# Read pointer position
print('The current pointer position is {0}'.format(
    mouse.position))

# Set pointer position
mouse.position = (10, 20)
print('Now we have moved it to {0}'.format(
    mouse.position))

# Move pointer relative to current position
mouse.move(5, -5)

# Press and release
mouse.press(Button.left)
mouse.release(Button.left)

# Double click; this is different from pressing and releasing
# twice on Mac OSX
mouse.click(Button.left, 2)

# Scroll two steps down
mouse.scroll(0, 2)

Example 2: python mouse listener

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 down = 0 or 1. Button up = -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)
