【Python】Pycharm + wx3 でエラー

PycharmのPython Console使用時に発生したエラー。

おそらくbackednをpyqt4からwxに変更したことも関係あると思われる。

def inputhook_wx3():
    """Run the wx event loop by processing pending events only.

    This is like inputhook_wx1, but it keeps processing pending events
    until stdin is ready.  After processing all pending events, a call to
    time.sleep is inserted.  This is needed, otherwise, CPU usage is at 100%.
    This sleep time should be tuned though for best performance.

    # We need to protect against a user pressing Control-C when IPython is
    # idle and this is running. We trap KeyboardInterrupt and pass.
    try:
        app = wx.GetApp()  # @UndefinedVariable
        if app is not None:
            assert wx.IsMainThread()  # @UndefinedVariable

            # The import of wx on Linux sets the handler for signal.SIGINT
            # to 0.  This is a bug in wx or gtk.  We fix by just setting it
            # back to the Python default.
            if not callable(signal.getsignal(signal.SIGINT)):
                signal.signal(signal.SIGINT, signal.default_int_handler)

            evtloop = wx.GUIEventLoop()  # @UndefinedVariable
            ea = wx.EventLoopActivator(evtloop)  # @UndefinedVariable
            t = clock()
            while not stdin_ready():
                while evtloop.Pending():
                    t = clock()

                #app.ProcessIdle()
                wx.WakeUpIdle()

wx3になって
wx.Thread_IsMain()　が wx.IsMainThread に変更されているのに
プログラム内ではwx2のままが原因。

ほかにも
wx.EventLoop()　が wx.GUIEventLoop() を使うよう推奨されていたので変更した。
