如何使用Python检测鼠标侧键 [英] How to detect mouse side buttons with Python

问题描述

我一直在使用pyhook和click事件的message属性，但是它似乎只能检测到三个标准按钮. 其他人甚至没有找到处理程序.

I've been using pyhook and the message attribute of the clicking events, but it seems to be able to detect just the three standard buttons. The others don't even get to the handler.

是否有办法检测鼠标可能具有的多余按钮?

Is there a way to detect the extra buttons that the mouse might have?

推荐答案

WH_MOUSE_LL确实钩住了XButton，PyHook的dll将其传递给python，但是python端的HookManager忽略了它们.但是，您可以跳过HookManager并直接使用cpyHook界面.

WH_MOUSE_LL does hook XButtons and PyHook's dll passes it through to python, but the HookManager on the python side ignores them. However, you can skip HookManager and use the cpyHook interface directly.

此示例在按钮被按下时将xbutton事件打印到控制台，并在按下鼠标左键时退出:

This example prints xbutton events to the console as they are pressed and exits when the left mouse button is pressed:

from pyHook import cpyHook, HookConstants
import pythoncom
import ctypes
user32 = ctypes.windll.user32

XBUTTON1 = 0x0001
XBUTTON2 = 0x0002

wm = { 0x020B: "WM_XBUTTONDOWN", 0x020C: "WM_XBUTTONUP", 0x0201: "WM_LBUTTONDOWN", }

def mouse_handler(msg, x, y, data, flags, time, hwnd, window_name):
    name = wm.get(msg, None)
    if name:
        xb = data >> 16  # high word indicates which xbutton
        print(name, xb & XBUTTON1, xb & XBUTTON2)
        if name == "WM_LBUTTONDOWN":
            user32.PostQuitMessage(0)
    return True  # True = pass the event to other handlers

try:
    cpyHook.cSetHook(HookConstants.WH_MOUSE_LL, mouse_handler)
    pythoncom.PumpMessages() # returns on WM_QUIT
finally:
    cpyHook.cUnhook(HookConstants.WH_MOUSE_LL)
