copied!<p>I'm not sure if this is germane, but some googling turns up that PyQt is pretty popular inside of Maya. You could try the technique <a href="http://www.highend3d.com/boards/lofiversion/index.php/t236041.html" rel="nofollow noreferrer">here</a> or <a href="http://www.highend3d.com/boards/index.php?showtopic=242116" rel="nofollow noreferrer">here</a> (explained <a href="http://groups.google.com/group/xsi_list/msg/dd500eb2420f3417?" rel="nofollow noreferrer">here</a> with source code) of creating a new threadloop via Maya and executing inside of that. It seems Maya has a module included that sets up a new thread object, with a QApplication inside it:</p> <pre><code>def initializePumpThread(): global pumpedThread global app if pumpedThread == None: app = QtGui.QApplication(sys.argv) pumpedThread = threading.Thread(target = pumpQt, args = ()) pumpedThread.start() </code></pre> <p>and then sets up a function to process the Qt events:</p> <pre><code>def pumpQt(): global app def processor(): app.processEvents() while 1: time.sleep(0.01) utils.executeDeferred( processor ) </code></pre> <p>You can probably do something similar with wxPython as well. (utils.executeDeferred is a Maya function.) Be sure to check out how to create a <a href="http://wiki.wxpython.org/Non-Blocking%20Gui" rel="nofollow noreferrer">non-blocking GUI</a> on the wxPython wiki. Instead of processEvents(), you'll want to set up an event loop and check for "Pending" events inside the (hopefully renamed?) pumpQt function above. (The wxPython source has a <a href="http://cvs.wxwidgets.org/viewcvs.cgi/wxWidgets/wxPython/samples/mainloop/mainloop.py" rel="nofollow noreferrer">Python implementation</a> of MainLoop.) Likely this should be done through the app.Yield() function, but I'm not sure.</p> <pre><code>def pumpWx(): global app def processor(): app.Yield(True) while 1: time.sleep(0.01) utils.executeDeferred( processor ) def initializePumpThread(): global pumpedThread global app if pumpedThread == None: app = wx.App(False) pumpedThread = threading.Thread(target = pumpWx, args = ()) pumpedThread.start() </code></pre> <p>The wxPython docs <a href="http://www.wxpython.org/docs/api/wx-module.html#SafeYield" rel="nofollow noreferrer">indicate SafeYield()</a> is preferred. Again, this seems like it could be a first step, but I'm not sure it will work and not just crash horribly. (There's some discussion about what you want to do on the <a href="http://www.nabble.com/app.MainLoop-vs.-Pending-Dispatch-td17921845.html" rel="nofollow noreferrer">wxPython mailing list</a> but it's from a few minor versions of wx ago.) There is also some indication in various forums that this technique causes problems with keyboard input. You might also try doing:</p> <pre><code>def processor(): while app.Pending(): app.Dispatch() </code></pre> <p>to deal with the current list of events.</p> <p>Good luck!</p>
