# @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.

# @FUNCTION: setup-wxwidgets
# @DESCRIPTION:
# Call this in your ebuild to set up the environment for wxGTK.  Besides
# controlling the wx-config wrapper this exports WX_CONFIG containing
# the path to the config in case it needs to be passed to a build system.
#
# In wxGTK-2.9 and later it also controls the level of debugging output
# from the libraries.  In these versions 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: http://docs.wxwidgets.org/trunk/overview_debugging.html
