# @BLURB: Manages build configuration for wxGTK-using packages.
# @DESCRIPTION:
# This eclass sets up the proper environment for ebuilds using the wxGTK
# libraries. Ebuilds using wxPython do not need to inherit this eclass.
#
# More specifically, this eclass controls the configuration chosen by the
# /usr/bin/wx-config wrapper.
#
# Using the eclass is simple:
#
# - set WX_GTK_VER equal to a SLOT of wxGTK
# - call setup-wxwidgets()
#
# The configuration chosen is based on the version required and the flags
# wxGTK was built with.

# inheriting the eclass. Can be either "3.0" or "3.0-gtk3".

# @FUNCTION: setup-wxwidgets
# @DESCRIPTION:
# Call this in your ebuild to set up the environment for wxGTK in src_configure.
# Besides controlling the wx-config wrapper, this exports WX_CONFIG containing
# the path to the config in case it needs to be passed to the build system.
#
# This function also controls the level of debugging output from the libraries.
# Debugging features are enabled by default and need to be disabled at the
# package level. Because this causes many warning dialogs to pop up during
# runtime, we add -DNDEBUG to CPPFLAGS to disable debugging features (unless
# your ebuild has a debug USE flag and it's enabled). If you don't like this
# behavior, you can set WX_DISABLE_NDEBUG to override it.
#
# See: https://docs.wxwidgets.org/trunk/overview_debugging.html
