wxWidgets-python - NotImplementedError: wx.GraphicsContext is not available on this platform.

[justjoheinz@…]

I am not sure which port exactly is causing the problem, the scenario is that I try to use a python programm which uses wxwdigets and I get the error:

NotImplementedError: wx.GraphicsContext is not available on this platform.

I found a bug report and a resolution for another program which can be seen here (nothing to do with macports): ​http://editra.org/forum/viewtopic.php?t=75

It seems that I need some variant of one of the many wxwidgets ports but I am not sure which one, or if it exists. I am happy to contribute more details if you send me the commands for the interesting debug information.

The thread you reference says that a) graphics context should already be enabled and b) to force it to be enabled we could add --enable-graphics_ctx to the configure args. The latter is what was requested for wxWidgets-python in #31804 but it failed to build and we don't know how to make it succeed.

The above post also says the graphics context was not added until wxWidgets 2.8. Which wxWidgets port(s) are you using -- wxWidgets? wxWidgets26? wxgtk? wxWidgets-python?

[justjoheinz@…]

How can I find out which port is used? Can you send me the relevant command?

[ryandesign (Ryan Carsten Schmidt)]

You could look through the output of "port installed"

Thanks! wxWidgets-python @2.8.10.1_2+gtk seems to be the only one.

So presumably also py26-wxpython since you're using it in python.

I just wanted to add that wxPython 2.9.4.0 seems to compile fine with --enable-graphics_ctx on 10.7, but I don't know how to test anything.

Cc Me!

I also got it working with wxWidgets 2.8. See #31804.

This should be fixed in r110234 and r110279. Please reopen in case it doesn't work.
