介绍

CustomTkinter 是一个基于 Tkinter 的 python UI 库，它提供了新的、现代的和完全可定制的小部件。它们像普通的 Tkinter 小部件一样创建和使用，也可以与普通的 Tkinter 元素结合使用。小部件和窗口颜色适应系统外观或手动设置的模式（‘light’，‘dark’），并且所有 CustomTkinter 小部件和窗口都支持 HighDPI 缩放（Windows，macOS）。使用 CustomTkinter，您将在所有桌面平台（Windows、macOS、Linux）上获得一致且现代的外观。

GitHub社区也非活跃，一直保持更新，收藏数高达7.4k

安装

使用 pip 安装模块：

pip3 install customtkinter

更新现有安装：尽可能经常更新，因为这个库正在积极开发中

pip3 install customtkinter --upgrade

看一下官方的展示demo

新建一个文件，输入一下代码，运行即可看到上面展示效果
