我在使用pyGTK应用程序时遇到了一些问题.我给线程一些时间来完成它的任务,如果有问题我只是继续但是警告用户.但是一旦我继续,这个线程就会停止,直到调用gtk.main_quit.这让我很困惑.

相关代码:

class MTP_Connection(threading.Thread):
    def __init__(self, HOME_DIR, username):
        self.filename = HOME_DIR + "mtp-dump_" + username
        threading.Thread.__init__(self)

    def run(self):
        #test run
        for i in range(1, 10):
            time.sleep(1)
            print i   

..........................

start_time = time.time()
conn = MTP_Connection(self.HOME_DIR, self.username)
conn.start()
progress_bar = ProgressBar(self.tree.get_widget("progressbar"),
                           update_speed=100, pulse_mode=True)
while conn.isAlive():
    while gtk.events_pending():
        gtk.main_iteration()
    if time.time() - start_time > 5:
        self.write_info("problems closing connection.")
        break
#after this the program continues normally, but my conn thread stops
