ilog.views.chart.IlvStyle.Change

ilog.views.chart.IlvStyle.ColorChange

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

IlvStyle.IntensityChange

Enclosing class:

IlvStyle

public abstract static class IlvStyle.ColorChange
extends IlvStyle.Change

An IlvStyle.Change subclass that modifies the colors of an IlvStyle. The ColorChange class modifies either:

• The fill color, if the rendering style is filled (see IlvStyle.isFillOn()).
• The stroke color, if the rendering style is not filled.

The ColorChange class also handles some cases where the fill or stroke paint are not instances of java.awt.Color. For example:

• It modifies the background color if the paint is an IlvPattern
• It modifies the colors of a gradient paint.

The color modification is performed by the changeColor(java.awt.Color) method, which must be implemented in concrete subclass.

Since:

JViews 5.5
