Overview

The FXGradientBar is a control that is used to edit color gradient, such as used in texture mapping and shape filling.

Events

The following messages are sent by FXGradientBar to its target:

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.

SEL_CHANGED

sent when anything about a segment changes; the message data is an integer indicating the segment number

SEL_SELECTED

sent when one or more segments are selected.

SEL_DESELECTED

sent when one or more segments are deselected.
