   再说主界面除标题栏、功能栏外的中央窗体，分为左右两部分！

   左半边几面由QWidget实现，包含三个QLabel、一个QPushButton，QLabel主要显示图片、文本信息，另外一个按钮就负责“立即体检”了。

   右半边由QSplitter实现分割窗体，又包含四个QWidget，每个QWidget又包含不同的组件，

   整体部分由QSplitter将左半边的QWidget与右半边的QSplitter分割，分割器分割部分均不可拖动！

    代码如下：

#include "content_widget.h"

ContentWidget::ContentWidget(QWidget *parent)

 //禁止拖动

 {

   好吧，代码比较多，而且基本没有注释，好的程序员注释是必不可少的，呵呵，自己写的程序也许只有自己能看懂！其实个人感觉看起来应该也不怎么费力，因为大多数代码也都是见名知意的。。。而且研究也是一个学习的过程！
