Python_数学绘图工具MathToolsPaint[项目]（动态组件与PaneWindow）（tkinter实现）【2022-01-17】
【v1.0.0版本】功能有限，但整体雏形框架已经搭好。实现时间：2天。
【注】 数学绘图工具–MathToolsPaint，版本Version 1.0.0。
【注1】将 Matploylib和turtle的绘制嵌入到tkinter的canvas中。
【注2】实现了 组件的动态生成显示与销毁。
【注3】具有 PaneWindow面板，更具实用性。
【注4】项目也会放在博主的Gitee仓库中。
【销毁组件实现思路】在pane上放上一个frame，在此frame上放canvas和其他组件，直接销毁frame即可。

2.界面截图
2.1 启动界面
2.2 PaneWindow调整
2.3 菜单栏展示
2.4 MatPlotlib绘制（将MatPlotlib嵌入tkinter的Canvas中）
- 点击“开启MPLOT工具栏”，在工具栏位置显示三个按钮
2.点击“生成求解区域”，会在下方生成Matplotlib的绘图区域与函数表达式输入框
3.输入一个表达式，点击“[MatPlotLibGo]”即可绘制出输入的函数
4.点击“解除求解区域”，则会销毁刚才生成的求解区域
5.点击“关闭MPLOT工具栏”，会销毁该功能工具栏
2.5 Turtle绘制（将Turtle嵌入tkinter的Canvas中）
【注】与MatPlotlib绘制功能用法一样，在此只展示几个运行图
3.软件功能展示（动态图）
