# @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 regularly pop up we add -DNDEBUG to
# CPPFLAGS by default, unless your ebuild has a debug USE flag and it's
# enabled. If you don't like this behavior you can set WX_DISABLE_DEBUG
# to disable it.
#
# See: http://docs.wxwidgets.org/trunk/overview_debugging.html
