manual event loop

Hi,
in version 2.4, the simple loop
while 1:
    while app.Pending():
        app.Dispatch()

was a useful replacement for app.MainLoop(). For version 2.5,
the loop
while 1:
    while app.Pending():
        app.Dispatch()

···

#
    sleep(0.001)
    #
    app.ProcessIdle()

(taken from wxPythonSrc-2.5.1.5/wxPython/demo/demoMainLoop.py)
results in a blank GUI with no interaction.
Does anybody know how to replace the new MainLoop() in Python?

P.S. The mainloop now uses the C++ class wxEventLoop, but I didn't see that wrapped for
Python.

Obviously it's been a while since I ran demoMainLoop... It did work with an earlier 2.5 build though. I'll try to figure out what is going on with it.

Not yet.
