Hi,

I see this exception (or similar, i.e. always the same attribute error
but the traceback starts at a different place).

This is with: 2.9.5.81-r73873

If I use "2.9.5.0.b20130318" with the same script it runs fine.

BaseApp is:
class BaseApp(wx.App, InspectionMixin):

Any hint on where to look as debugging in WingIDE throughs me all kind
of errors when I try to step through.

Werner

BTW, I tried without WIT, but still the same.

Is there any more to that traceback? I don't see where the call to
ProcessIdle is coming from.

This is another case of a method not being documented, and so Phoenix is
not seeing it. Although there still is a ProcessIdle in the C++ wxApp,
it and some other event loop related methods are now implemented (and
documented) in the wxEventLoop class so that is probably what should be
used now. You may try replacing the call to self.ProcessIdle()
(assuming self is the app object) with:

self.GetMainLoop().ProcessIdle()

or maybe:

wx.EventLoop.GetActive().ProcessIdle()

That was it, I'll give you another one below.

This only happens in my code when I use matplotlib stuff - it doesn't
happen when I use the simple wxembedded sample to test.

There is no call to ProcessIdle in my code and the one time where I see
it in matplotlib it is commented out, but instead they call wx.WakeUpIdle()

I see in FigureCanvasWx in matplotlib they are using a timer in
"draw_idle" which in turn calls _onDrawIdle which uses
wx.GetApp().Pending which I can only find in 2.8 wx doc and not in 2.9.5
nor Phoenix.

P.S.
Below two tracebacks I get from the same script just by restarting it.

Start my script with matplot figures in WingIDE:
