Overview

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.
