Qt问题（二）：无法定位程序输入点于动态链接库
动态链接库（Dynamic Link Library，简称DLL）是一种可执行文件格式，常见于Windows操作系统中，而在Linux和macOS等其他操作系统中，相似的概念通常被称为共享库（Shared Library）。动态链接库允许程序在运行时加载所需的代码和数据，而不是在编译时静态链接到应用程序中。这种方式带来了几个重要的优点：

【浅入浅出】Qt多线程机制解析：提升程序响应性与并发处理能力
在学习QT线程的时候我们首先要知道的是QT的主线程，也叫GUI线程，意如其名，也就是我们程序的最主要的一个线程，主要负责初始化界面并监听事件循环，并根据事件处理做出界面上的反馈。但是当我们只限于在一个主线程上书写逻辑时碰到了需要一直等待的事件该怎么办？它的加载必定会带着主界面的卡顿，这时候我们就要去使用多线程。

QT creator开发环境下 界面更改后运行程序不能实时更新或者在源文件添加该控件后无法编译的问题
在使用QT Creator开发界面的过程中，偶尔会出现添加控件后，运行程序后，界面控件无法更新的情况，或者在源文件使用该控件却出现无法编译的情况，使用QT Creator 4.8.2也会出现这个情况，也不知道这种情况会不会在以后有所改善。
