# QThread
|
||
|
||
## 1、继承QThread
|
||
[运行 InheritQThread.py](InheritQThread.py)
|
||
|
||

|
||
|
||
## 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
|
||

|
||
## 4、线程休眠唤醒
|
||
[运行 WakeupThread.py](WakeupThread.py)
|
||
|
||
使用 `QWaitCondition` 的 `wait` 和 `wakeAll` 方法
|
||
