[源码]Python Tkiner 写的截图小工具 实现了大部分基础功能
最近在写一些小工具，因为是给别人用的需要界面，刚开始使用pyQT5 功能强大，但是打包后一个小工具 就有几十兆 有点蛋疼而且还很消耗资源；后面改用TK，TK明显简洁很多，功能同样也若很多！ 因为有截图需求，就抽空写了这个工具，全当练习。过程当中遇到过好多蛋疼的事情，功能基本实现后发出来给大家分享一下，我个人还是比较喜欢python这门语言的！ 实现思路：3.1.新建一个最小化窗口，利用线程启动监听"ctrl+a"启动截图窗口3.2.截图窗口初始化时利用 pyautogui.screenshot 截取全屏（类似PRTSC）作为子窗口的背景（在这搞了好久，后面没办法只有利用canvas设置背景），子窗口最大化取消菜单栏3.3.在主窗口上的canvas上用绑定鼠标事件，根据鼠标选取截图范围，和鼠标操作相关功能3.4.保存功能是根据截图范围重新截图生成文件保存 代码 main_UI.py fromtkinter.messageboximportshowinfo
