Qt开发图形界面上位机软件显示通过TCP接受数据图像，执行bash命令启动Geant 4

上位机软件功能

本人设计的上位机主要分为信号图像显示区、按键和参数设置区和文字信息区三大部分。 整个上位机软件主要分为三部分： 1. 启动和关闭 Geant4 物理仿真软件并且设置相关参数。 2. 显示探测器能量沉积数字信号。 3. 显示 TCP连接状态信息和 Geant 4 探测器能量沉积。

但是有一点我很不理解，为了实现每次接收到TCP数据帧，都能够更新信号图像，我把new空间放到了header文件中，在cpp文件的doProcessNewConnect函数中怎么都没有办法实现。本人觉得这是不好的编程习惯但是也是无奈之举。。。如果你知道欢迎回复！
