# A GL context is an object representing the OpenGL state information.
# Multiple GL context may share display lists to conserve memory.
# When drawing multiple windows, it may be advantageous to share not only
# display lists, but also GL contexts. Since the GL context is created
# for a certain frame-buffer configuration, sharing of GL contexts is
# only possible if the windows sharing the GL context all have the same
# GL visual.
# However, display lists may be shared between different GL contexts.
#
class FXGLContext < FXId
# The visual [FXGLVisual]
attr_reader :visual
# Construct an OpenGL context.
# If _other_ is a reference to an existing FXGLContext, this context will
# share display lists with that other context.
# Otherwise, this context will use its own private display list.
def initialize(app, visual, other=nil) # :yields: theGLContext
end
# Return +true+ if it is sharing display lists.
