Tkinter 制作的NotePad记事本
本帖最后由 你听说了吗？ 于 2023-9-5 17:08 编辑最近在学习tkinter, 界面丑是丑了点，但是打包方便，比pyqt什么的小多了，功能比界面重要：
下面是源码，供大家参考：
源代码：
```python

打包方法
使用`auto-py-to-exe`打包；
单独复制img目录何notepad.py文件到另一目录；
修改源代码中的`img`文件路径为img目录的绝对路径；
打包成单个文件；
选着资源文件夹；
打包生成exe可执行文件；

缺少的img文件补上； 本帖最后由 lookfeiji 于 2023-9-5 14:08 编辑
自己搞几个.gif的文件"new_file", "open_file", "save", "cut", "copy", "paste", "undo", "redo", "find_text"命这几个名字，还有一个editor.ico图标文件，丑是丑了点，能用 大佬，缺少一堆的img元素呀，也发一下吧。 學習了，謝謝分享！ 这个不错，学习了。 感谢分享 感谢分享，值得学习学习 看起来比c#实现复杂太多了 实现这些功能，py的代码不少了，跟aardio比的话{:1_907:} {:1_921:}{:1_921:}
行号是固定的，并不能随滚动条变化。
不知道是故意这样设计，还是没注意到。
