public class GradientBar extends MicrobaComponent
IMPORTANT: alpha featre not implemented. Stubs only.

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);
