bridges.base.Symbol Class Reference

Inheritance diagram for bridges.base.Symbol:

Detailed Description

This is a class in BRIDGES for deriving a number of Symbol objects for use in a SymbolCollection.

It is not intended that objects from this class will be directly created. Rather, we expect that classes that derive from this class be instantiated such as Circle, Label, Polyline, Polygon, Rectangle.

Symbols correspond to a simplified subset of SVG paths and shapes for custom visual representations in BRIDGES.

The stroke is the actual lines that get drawn (such as the perimeter of a rectangle) and its style is controlled by setStrokeColor(), setStrokeWidth(), and setStrokeDash().

The inside of the Symbol can be colored independently from the stroke using setFillColor().

The overall Symbol can be made more of less visible by adjusting its opacity using setOpacity().
