Detailed Description

2d中心组件，继承CentralWidget

内部的绘画以及标注相关的动作交由Label类命令的撤销和重做交由Command2D类标注文件的解析和存储交由Parse类进行处理

Reimplemented from My::CentralWidget.

◆ closeFile()

void CentralWInit2D::closeFile ( )

virtual

关闭当前文件

关闭文件

Reimplemented from My::CentralWidget.

◆ createShape()

void CentralWInit2D::createShape ( My::shapeStatus s )

virtual

创建标注形状

当触发创建各种形状时，会经过mainwindow调用该函数

Reimplemented from My::CentralWidget.

◆ deleteLabel()

void CentralWInit2D::deleteLabel ( )

virtual

删除标注

当deletepolygons动作被触发时，会经由mainwindow调用该函数

Reimplemented from My::CentralWidget.
