#
# A Color Bar is a widget which controls the brightness (value) of a
# color by means of the hue, saturation, value specification system.
# It is most useful when used together with the Color Wheel which controls
# the hue and saturation.
# The options <tt>COLORBAR_HORIZONTAL</tt> and <tt>COLORBAR_VERTICAL</tt> control the orientation
# of the bar.
#
# === Events
#
# The following messages are sent by FXColorBar 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.
#
# === Color bar orientation
#
# +COLORBAR_HORIZONTAL+:: Color bar shown horizontally
# +COLORBAR_VERTICAL+:: Color bar shown vertically
