python鼠标事件函数举例

以下是几个常用的 Python 鼠标事件函数示例：

1. 鼠标左键单击事件：

import pygame

def handle_events():
    for event in pygame.event.get():
        if event.type == pygame.MOUSEBUTTONDOWN and event.button == 1:  # 鼠标左键单击事件
            print("Left button clicked at", event.pos)

2. 鼠标移动事件：

import pygame

def handle_events():
    for event in pygame.event.get():
        if event.type == pygame.MOUSEMOTION:  # 鼠标移动事件
            print("Mouse moved to", event.pos)

3. 鼠标滚轮事件：

import pygame

def handle_events():
    for event in pygame.event.get():
        if event.type == pygame.MOUSEBUTTONDOWN and event.button == 4:  # 鼠标滚轮向上滚动事件
            print("Mouse wheel up")
        elif event.type == pygame.MOUSEBUTTONDOWN and event.button == 5:  # 鼠标滚轮向下滚动事件
            print("Mouse wheel down")

注意：以上示例中需要使用 Pygame 模块来处理鼠标事件。
