我正在尝试构建实时流下载器。它创建了多个线程以同时下载流。我希望每次启动线程并在下载程序中使用新名称时刷新表。这将创建GUI并启动主下载程序线程（在setupUi末尾启动下载程序）：

原始类太长，因此这是下载器类的相关部分。它为每个下载器创建一个线程。每个人都会收到一个名称，以尝试从自身列表中下载：
class ThreadKontrol():
def threadleriolustur(self):
listthread=threading.Thread(target=self.listolustur) #gets a name list from function
listthread.start()
time.sleep(2)
for thread in range(1,self.threadnum+1):
ConfigIslem.threadconfigolustur(thread) #creates a config file for each thread
self.createhread(thread) # starts every thread
while True:
time.sleep(10) # keeps program from ending
def createthread(self,thread):
t=threading.Thread(target=self.runthread,args=(thread,))
t.start()
time.sleep(2)
def changestat(self,row,column,text): #changes the relevant table box to text
item = self.downloadertable.item(row,column)
item.setText(text)
def runthread(self,thread):
while True:
self.changestat(thread-1,0,"Running")
name=self.getname() # gets a name from function to try if it's available for download
self.changestat(thread-1,1,name) # prints the name to relevant box in table
indir=indirme(name,thread) # this is the downloader object
value=indir.startDownload()
del indir #deletes the downloader object once complete
time.sleep(3)
self.sendnameback(name) #sends the name back to list to try another time
所以它可以工作，但是我必须将焦点从GUI窗口移开，然后重新放回它，以便刷新表。我希望它会自动刷新。
