pyqt QObject：無法爲處於不同線程中的父項創建子項

QObject：無法爲處於不同線程中的父項創建子項。 （Parent是另外，QTextDocument（0x9919018），父母的線程的QThread（0x97331e0），當前線程被flooderthread（0x97b4c10） 錯誤表示很抱歉，因爲是新來這裏的PyQt 是代碼：pyqt QObject：無法爲處於不同線程中的父項創建子項

我知道代碼是完呢，但它應該工作，我想這個問題是myfun.log功能...

    def run(self): 
     connecter() # this is the culprit

在您的fun.main()中，您可以撥打connecter()來設置您的所有信號/插槽連接。此調用正在您的主線程中發生。但是，然後你有每個線程也調用該方法，這是試圖跨線程重複連接到對象。實際的崩潰可能比這個函數更深，因爲它是信號發射的結果，但是我發現跳到代碼中來實現更深入的代碼太困難了。很可能你有線程在不應該的時候直接修改GUI元素。

一旦你有一個固定的，你有一個錯字等，這將使它崩潰：

def main(self): 
    connecter() 
    ... 
    time.sleep(3) 
    gui() 
    f5.start() 
    gui() 
    self.sleep(3) # should be time.sleep(3) 
    gui() 
    ...
從這個

除此之外，我只是想指出的是，這個腳本是非常難追。你正在使用全局變量，所以很難知道在哪裏定義了某些變量和函數調用。你必須滾動一堆，追逐它們。您可能想要在繼續​​滾雪球之前停止並重新組織它。
我會高度建議拿起這樣的書：http://www.qtrac.eu/pyqtbook.html
你應該關注的是組織適當的類。您目前的課程結構需要大量的複習，所以您甚至可能想要選擇一本好的Python書籍來首先學習如何編寫課程。我意識到你只是在學習，這就是爲什麼我希望這個建議能幫助你引導你正確的方向。

thanx很多，因爲我說我還沒有完成代碼......並感謝這本書，我正在尋找這樣的東西:) – memomk
