    <p>I am developing a program that uses Twisted and wxReactor. Everytime I try to exit the application, it hangs, and I have to force quit it. My wxPython OnClose() event does call reactor.stop(), which to my knowledge should fix this issue. In my quest for an answer, I've come across this ticket: www.twistedmatrix.com/trac/ticket/3948.<br> I've tried a patch listed on the page, with no luck. I've been at this problem for 2 weeks now, and am pretty desperate :).</p> <p>To give you all some background on this project: It is a freeware client that uses sockets to connect to a multiplayer game server (currently plays Monopoly and Uno). If you run it, you will immediately notice there are no graphics. That is because this client only provides audio feedback through speech synthesis and sound effects. The target audience of this project is visually impaired gamers. </p> <p>To test the issue, run python rsg.py (which can be found in the src folder. In case you need to know, I use Python 2.6.5). In a terminal, you will see the output the program produces (which is mostly what the server sends to our client). Once you see the line "Connection Made" (which should print very shortly after running), try closing the program (by clicking the X). The client will hang for a few seconds, and then you will need to force quit the application (on Ubuntu, it comes up asking if I want to force quit the application). </p> <p>I do have an idea of why it doesn't exit properly. When I ran it through gdb, two threads weren't exiting. Strange enough, if the server closed the connection, then I exited the program, it would work fine. </p> <p>I really appreciate all help. Thank you in advance.</p> <p><strong>Edit</strong> <em>Since I was asked to provide a basic demo of my problem, here it is:</em></p> <pre><code>import wx import sys from twisted.internet import wxreactor wxreactor.install() # import t.i.reactor only after installing wxreactor: from twisted.internet import reactor from twisted.protocols.basic import LineReceiver from twisted.internet.protocol import ClientFactory class ZGPClient(LineReceiver): """Our client object.""" def lineReceived(self, datavar): "As soon as any data is received" print datavar class EchoFactory(ClientFactory): protocol = ZGPClient def startedConnecting(self, connector): global conn conn = connector print 'Started to connect.' def sendData(self, data=""): conn.transport.write(data.encode("ascii", "ignore") + "\n") class main_window(wx.Frame): def __init__(self, parent, id, title): super(main_window, self).__init__(parent, id, title, style=wx.DEFAULT_FRAME_STYLE) self.Bind(wx.EVT_CLOSE, self.OnClose) self.Show(True) def OnClose(self, event): reactor.stop() sys.exit() if __name__ == "__main__": app = wx.App() frame = main_window(None, wx.ID_ANY, "RS Games Client - No Game") reactor.registerWxApp(app) sockObj = EchoFactory() reactor.connectTCP("rsgamesmonserver.webhop.org", 3555, sockObj) reactor.run() app.MainLoop() </code></pre>

    1. COWhy don't you abstract the problem into a simple demo code that reproduces the issue and post it on SO? This will attract more people to look at your issue.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
