python3写的记事本
本帖最后由 小小大鱼 于 2016-3-19 14:49 编辑之前看到有人发了记事本，而且还更新，最近在学tkinter，然后也摸索着写了一个，功能相当简陋，有些功能暂时还实现不了......而且还很丑。
完整代码在下面......
3.19日更新：
本来是3.18更新，结果恢复了，什么也没有，今天重新更新。
1.实现左侧显示行号功能
2.右下角显示当前光标位置
3.取消代码隐藏
还有一些bug，也希望大家能帮我指出来，帮我改进。
比如：RuntimeError: main thread is not in main loop这个错误还不知道怎么处理。
没能实现滚动条

代码上的颜色字体，酷炫啊！
用的sublime text3 拈花小仙 发表于 2016-2-1 17:38
这么厉害
慢慢学的，有些功能还实现不了，学习中.... {:10_277:学习下 6666楼主牛b 看看学习下 回复看看 哈哈
