Class GradientBar
- All Implemented Interfaces:
ImageObserver
,MenuContainer
,Serializable
- Direct Known Subclasses:
GradientEditor
A concrete implementation of JComponent. Displays an area filled with gradient color (palette). The color and alpha value (transparency) is linearly interpolated between key points.
The color key points are provided by the data model in combination with color
column (index) and color position column (index). Each row in the model
represents a colored key point. Color values are expected to be of type
Color
and position values of type Number
with integer
precision.
The alpha key points are provided by the alpha model in combination with
alpha column (index) and alpha position column (index). Each row in the model
represents an alpha key point. Alpha values are expected to be of type
Number
with floating-point precision ranging form 0.0f (transparent)
to 1.0f (opaque) and position values of type Number
with integer
precision.
Example:
GradientBar bar = new GradientBar(); bar.setDataModel(myColorModel); bar.setColorColumn(0); bar.setColorPositionColumn(1); bar.setAlphaModel(myAlphaModel); bar.setAlphaColumn(1); bar.setAlphaPositionColumn(0);
