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。 所以这就是我的问题:我真的很喜欢Qt的简单性和Python的强大功能,但它让我有点过分了。 我想使用PyQt和libtorrent构建一个非常简单的torrent客户端。 我甚至已准备好使用该代码来下载一个torrent。 虽然,我在将应用程序代码与Qt的代码集成时遇到了麻烦。 这是torrent.py的代码: #!的/ usr / bin中/蟒蛇 导入系统 来自PyQt4导入QtCore,QtGui 导入libtorrent为lt 进口时间
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_())

主要问题是,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代码放入那个花哨的Qt窗口(将所有数据打印到列表视图中)。 请帮助我。
答案 0 :(得分:0)
您的问题是您在app.exec_()
之前有一些代码。窗口显示何时执行。部分
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)
应该从main函数中删除,并且应该在__init__
MyForm
中启动的函数中的单独线程中运行。
有点不清楚你的QListView问题是什么。我建议您使用QTreeWidget,我发现documentation非常有帮助。
