# A form object is an X11 packet definition. We use forms to encode
|
|
# and decode X11 packets as we send and receive them over a socket.
|
|
#
|
|
# We can create a packet definition as follows:
|
|
#
|
|
# class Point < BaseForm
|
|
# field :x, Int8
|
|
# field :y, Int8
|
|
# end
|
|
#
|
|
# p = Point.new(10,20)
|
|
# p.x => 10
|
|
# p.y => 20
|
|
# p.to_packet => "\n\x14"
|
|
#
|
|
# You can also read from a socket:
|
|
#
|
|
# Point.from_packet(socket) => #<Point @x=10 @y=20>
|
