Overview

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 COLORBAR_HORIZONTAL and COLORBAR_VERTICAL 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.
