FXColorRing.rb

module Fox
  #
  # A Color Ring widget provides an intuitive way to specify a color.
  # The outer ring of the widget is rotated to control the hue of the color
  # being specified, while the inner triangle varies the color saturation
  # and the brightness of the color.  The color saturation axis of the
  # triangle goes from a fully saturated "pure" color to "pastel" color;
  # the brightness goes from black to a bright color.
  #
  # === Events
  #
  # The following messages are sent by FXColorRing to its target:
  #
  # +SEL_CHANGED+::  sent continuously while the user is dragging the spot around; the message data is a three-element array containing the hue, saturation and value values.
  # +SEL_COMMAND+::  sent when the user releases the mouse button and "drops" the spot at its new location; the message data is a three-element array containing the hue, saturation and value values.
  # +SEL_LEFTBUTTONPRESS+:: sent when the left mouse button goes down; the message data is an FXEvent instance.
  # +SEL_LEFTBUTTONRELEASE+:: sent when the left mouse button goes up; the message data is an FXEvent instance.
