最近我开始了我的Python练习。这是非常有用的PL，特别是当你使用Linux时。 所以这里是我的问题：我非常喜欢Qt的简单性和Python的强大功能，但它已经让我变得有点过度了。 我想用PyQt和libtorrent构建一个非常简单的torrent客户端。 我甚至准备好了使用该代码来下载当前的一个种子。 虽然我在将应用程序代码与Qt代码集成时遇到了麻烦。 这里的torrent.py的代码： ＃在/ usr/bin中/ Python的 进口SYS 从PyQt4的进口QtCore，QtGui 进口libtorrent为LT 进口时间PyQt简单的洪流客户端
from torrent_ui import Ui_Form, ses
class MyForm(QtGui.QMainWindow):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
self.ui = Ui_Form()
self.ui.setupUi(self)
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
myapp = MyForm()
myapp.show()
ses.listen_on(6881, 6891)
#e = lt.bdecode(open("test.torrent", 'rb').read())
info = lt.torrent_info("g.torrent")
h = ses.add_torrent({'ti': info, 'save_path': './'})
print 'starting', h.name()
while (not h.is_seed()):
s = h.status()
state_str = ['queued', 'checking', 'downloading metadata', 'downloading', 'finished', 'seeding', 'allocating', 'checking fastresume']
print '\r%.2f%% complete (down: %.1f kb/s up: %.1f kB/s peers: %d) %s' % (s.progress * 100, s.download_rate/1000, s.upload_rate/1000, s.num_peers, state_str[s.state]),
sys.stdout.flush()
#ses.pause()
time.sleep(1)
print h.name(), 'complete'
sys.exit(app.exec_())
从PyQt的生成的代码：

主要的问题是，当torrent下载工作时，Qt应用程序窗口不显示。另一个问题是我不知道如何将libtorrent代码放入那个奇特的Qt窗口（将所有数据打印到列表视图中）。 请帮助我。
