最近我開始了我的Python練習。這是非常有用的PL,特別是當你使用Linux時。 所以這裏是我的問題:我非常喜歡Qt的簡單性和Python的強大功能,但它已經讓我變得有點過度了。 我想用PyQt和libtorrent構建一個非常簡單的torrent客戶端。 我甚至準備好了使用該代碼來下載當前的一個種子。 雖然我在將應用程序代碼與Qt代碼集成時遇到了麻煩。 這裏的torrent.py的代碼: #在/ usr/bin中/ Python的 進口SYS 從PyQt4的進口QtCore,QtGui 進口libtorrent爲LT 進口時間PyQt簡單的洪流客戶端

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_())

主要的問題是,當torrent下載工作時,Qt應用程序窗口不顯示。另一個問題是我不知道如何將libtorrent代碼放入那個奇特的Qt窗口(將所有數據打印到列表視圖中)。 請幫助我。

你的問題是你在app.exec_()之前有一些代碼。該窗口顯示何時執行。該部分

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) 

應該從主要功能被刪除,應在運行,也許在一個單獨的線程,在在的MyForm__init__啓動的功能。

這是有點不清楚你的問題與QListView是。我建議你使用QTreeWidget,我發現documentation非常有幫助。
