# QThread
PyQt多线程的简单使用例子
## 1、继承QThread
[运行 InheritQThread.py](InheritQThread.py)
![InheritQThread](ScreenShot/InheritQThread.png)
## 2、moveToThread
[运行 moveToThread.py](moveToThread.py)
![moveToThread](ScreenShot/InheritQThread.png)
## 3、线程挂起恢复
[运行 SuspendThread.py](SuspendThread.py)
注意,这里只是简单演示,在应用这些代码时要小心
1. 这里使用windows的api实现主要用到`SuspendThread`和`ResumeThread`函数
1. 利用`ctypes.windll.kernel32.OpenThread(win32con.PROCESS_ALL_ACCESS, False, int(QThread.currentThreadId()))`
1. 得到线程的句柄,然后就可以通过上面的两个函数对其进行挂起与恢复
`ctypes.windll.kernel32.TerminateThread`终止线程,不推荐
![SuspendThread](ScreenShot/SuspendThread.gif)
## 4、线程休眠唤醒
[运行 WakeupThread.py](WakeupThread.py)
使用 `QWaitCondition``wait``wakeAll` 方法
