Tree component

The tree component is one of the four graphic components supplied with JViews TGO. It provides a hierarchical view of the data contained in a data source. A tree has one or more root nodes, from which all the other nodes descend. Each tree node may be associated with a business object (for example, a managed object, an alarm, or a service). It has a number of graphic properties (for example, a label, an icon, a tooltip) that are set according to the values of one or more attributes of the object. The way in which business object attribute values map to the graphic representation of the business object is determined by the style sheets of the tree. For details on business objects, refer to Introducing business objects and data sources.
