Chaco & WX fail

[fred4ets]

Hello,

Chaco fails to run with ETS_TOOLKIT set to "wx"

For instance, any example in Chaco demo directory fail :

python3 scatter.py

This looks like an Enable issue - I think the problem is that the appropriate fixes for wxPython 4 haven't been merged yet: see https://github.com/enthought/enable/pull/403

Hi,

OK. I just updated sources.

Now, when I run scatter.py, I get the following:

@fred4ets Thank you very much for trying the source. Sorry that https://github.com/enthought/enable/pull/403 did not fix the problem. May I ask which scatter.py file you try and what packages did you have when you tested this? These information will expedite the process of tracking down the issues and actually making sure the issue is fixed. Thanks again.

[fred4ets]

I run scatter.py from Chaco's demo/basic.

python 3.7.3 + wx 4.0.4 on debian stable x86_64

Traits packages installed & used: chaco-4.8.1-dev 87 enable-4.8.1.dev90 traitsui-7.2.0.dev416-py3.7.egg traits-6.2.0.dev1651

Please ask if you want more info.

Thank you very much @fred4ets. This will be looked into.

Any news about this issue ?

Thanks.

@fred4ets sorry for not getting back to you sooner. I am unable to reproduce the error you report above https://github.com/enthought/chaco/issues/531#issuecomment-740546173 with the latest enable and chaco. I tried reproducing this on windows + python 3.6 but it is possible that this is a platform-specific issue (linux only). I opened https://github.com/enthought/enable/issues/798 to track the issue in enable
