alb_cb_moon,
Thank you, but I still have a problem...
This is a wxWidgets project that starts with an auto-generated code.
wxFormBuilder said it needed to convert the code. Accepting that, generating the code, saving, and trying to build in Code::Blocks now produces a build error:
'wxMessageBox' was not declared in this scope'
I reinstalled everything as described at http://wxpack.sourceforge.net/Tutorials/CodeBlocks, but still get the same error.
Edit: Sorry, didn't generate inherited class... Works fine now.
Thanks for helping.
