QObject: Cannot create children for a parent that is in a different thread. (Parent is QTextDocument(0x9919018), parent's thread is QThread(0x97331e0), current thread is flooderthread(0x97b4c10) error means ? am sorry because am new to pyqt here is the code :
QObject:不能为处于不同线程的父类创建子对象。(父类是QTextDocument(0x9919018)，父线程是QThread(0x97331e0)，当前线程是流线程(0x97b4c10)错误是什么意思?抱歉，这里是pyqt的新代码:
i know the code is finished yet but it should work i guess the problem is with myfun.log function...
我知道代码已经完成了，但它应该可以工作，我想问题在于myfun。对数函数…

I have almost no idea whats going on in your code, in terms of its intent, but here is the offending line of code causing your crash:
我几乎不知道你的代码中发生了什么，从它的意图来看，但这里是导致你崩溃的代码行:
class flooderthread(QtCore.QThread):
...
def run(self):
connecter() # this is the culprit
In your fun.main(), you call the connecter() once already to set up all your signal/slot connections. This call is occurring in your main thread. But then you have each thread also calling that method, which is trying to make duplicate connections to objects across threads. The actual crash may be caused much deeper than this function, because its the result of signal firing, but I find it just too difficult to hop around the code to get any deeper. Most likely you are having the thread directly modify GUI elements when it shouldn't.
在您的fun.main()中，您调用connecter()，它已经设置了所有的信号/槽连接。这个调用发生在主线程中。但是，每个线程都调用该方法，该方法试图在多个线程之间复制对象。实际的崩溃可能比这个函数要深得多，因为它是信号触发的结果，但是我发现很难在代码周围跳转到更深的地方。最可能的情况是，线程不应该直接修改GUI元素。
Once you have that fixed, you have one other typo that will make it crash:
一旦你有了那个固定的，你就会有另一个错误，它会使它崩溃:
def main(self):
connecter()
...
time.sleep(3)
gui()
f5.start()
gui()
self.sleep(3) # should be time.sleep(3)
gui()
...
Aside from this, I just want to point out that this script is extremely hard to follow. You are making use of globals everywhere, so its hard to know where certain variables and function calls were defined. You have to scroll around a bunch, chasing them down. You may want to stop and reorganize this before it continues to snowball.
I would highly suggest picking up a book like this: http://www.qtrac.eu/pyqtbook.html
What you should focus on is organizing proper classes. Your current class structures need a lot of review, so you may want to even pick up a good python book to first learn how to write classes. I realize you are just learning, which is why I am hoping this advise will help steer you in the right direction.
除此之外，我想指出的是，这个脚本非常难以遵循。您正在到处使用全局变量，因此很难知道某些变量和函数调用的定义。你必须滚动一串，把它们追下去。你可能想在它继续滚雪球之前停止并重新组织它。我强烈建议你选一本这样的书:http://www.qtrac.eu/pyqtbook.html你应该关注的是组织合适的课程。您当前的类结构需要大量的审查，因此您可能想要学习如何编写类的好python书籍。我知道你只是在学习，所以我希望这个建议能帮助你找到正确的方向。
