# = WxSugar - Accessors
#
# The default WxRuby interface has lots and lots of methods like
#
# * get_position()
# * set_size(a_size)
# * is_checked()
#
# and so on. Methods that retrieve set, or query attributes of an object
# are more normally in Ruby called simply by the attribute name:
#
# * position()
# * size = a_size
# * checked?
#
# This extension creates an alias for every WxRuby instance method that
# begins with +get_+, +set_+ or +is_+. Note that if you are calling a
# 'setter' method on self, you must explicitly send the message to self:
#
# # set's self size to be 100px by 100px
# self.size = Wx::Size.new(100, 100)
# # only sets the value of a local variable 'size'
# size = Wx::Size.new
