Unlike direct tests of __cplusplus, using this macro also works with
(recent enough, i.e. MSVS 2015.3 or later) MSVC versions, even if
/Zc:__cplusplus is not used.
This simplifies some checks and makes some other ones (notably the check
for C++20 used before wxALLOW_COMBINING_ENUMS macro definition) work
with MSVC versions with C++20 support as intended.
This directory contains tests for the library and is mostly useful for the
library developers. See the samples subdirectory for the examples that are
more useful to the application developers using the library.
If you do work on the library itself and would like to modify an existing or
add a new test, please see docs/contributing/how-to-write-unit-tests.md for
more information.
This file also contains the instructions for running the tests if you'd just
like to do it to confirm that the library works correctly.
