    <p>I suggest you look at the <a href="http://docs.python.org/library/threading.html" rel="nofollow noreferrer">threading module</a>. By subclassing the <code>Thread</code> class you can create new threads for time intensive jobs. </p> <p>Then for communication between the the threads you can use either <a href="http://pubsub.sourceforge.net/" rel="nofollow noreferrer">pubsub</a> or <a href="http://pydispatcher.sourceforge.net/" rel="nofollow noreferrer">pydispatcher</a>, I haven't tried the latter so I can't comment on it but I would recommend pubsub for its ease of use and the fact that its apart of wxpython is a bonus.</p> <p><a href="http://wiki.wxpython.org/LongRunningTasks" rel="nofollow noreferrer">Here </a>is a wxpython wiki page on running long tasks, skip to the end if you want the simplest example usage of threading. </p> <hr> <p>Heres a simple (runnable) example of how you could use <code>pubsub</code> to send messages from your workerThread to your <code>GUI</code>.</p> <pre><code>import time import wx from threading import Thread from wx.lib.pubsub import Publisher class WorkerThread(Thread): def __init__(self): Thread.__init__(self) #A flag that can be set #to tell the thread to end self.stop_flag = False #This calls the run() to start the new thread self.start() def run(self): """ Over-rides the super-classes run()""" #Put everything in here that #you want to run in your new thread #e.g... for x in range(20): if self.stop_flag: break time.sleep(1) #Broadcast a message to who ever's listening Publisher.sendMessage("your_topic_name", x) Publisher.sendMessage("your_topic_name", "finished") def stop(self): """ Call this method to tell the thread to stop """ self.stop_flag = True class GUI(wx.Frame): def __init__(self, parent, id=-1,title=""): wx.Frame.__init__(self, parent, id, title, size=(140,180)) self.SetMinSize((140,180)) panel = wx.Panel(id=wx.ID_ANY, name=u'mainPanel', parent=self) #Subscribe to messages from the workerThread Publisher().subscribe(self.your_message_handler, "your_topic_name") #A button to start the workerThread self.startButton = wx.Button(panel, wx.ID_ANY, 'Start thread') self.Bind(wx.EVT_BUTTON, self.onStart, self.startButton) #A button to stop the workerThread self.stopButton = wx.Button(panel, wx.ID_ANY, 'Stop thread') self.Bind(wx.EVT_BUTTON, self.onStop, self.stopButton) #A text control to display messages from the worker thread self.threadMessage = wx.TextCtrl(panel, wx.ID_ANY, '', size=(75, 20)) #Do the layout sizer = wx.BoxSizer(wx.VERTICAL) sizer.Add(self.startButton, 0, wx.ALL, 10) sizer.Add(self.stopButton, 0, wx.ALL, 10) sizer.Add(self.threadMessage, 0, wx.ALL, 10) panel.SetSizerAndFit(sizer) def onStart(self, event): #Start the worker thread self.worker = WorkerThread() #Disable any widgets which could affect your thread self.startButton.Disable() def onStop(self, message): self.worker.stop() def your_message_handler(self, message): message_data = message.data if message_data == 'finished': self.startButton.Enable() self.threadMessage.SetLabel(str(message_data)) else: self.threadMessage.SetLabel(str(message_data)) if __name__ == "__main__": app = wx.PySimpleApp() frame = GUI(None, wx.ID_ANY, 'Threading Example') frame.Show() app.MainLoop() </code></pre>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
