Detailed Description

Gadget.

Library: dbgraphe

The IliDbGrapher class defines a grapher gadget connected to two data sources (one for nodes and one for links). The following function keys are predefined:

The F9 key refreshes all nodes and links.
The Insert key adds a new node.
The Delete key deletes the selected node or selected link.
A drag between two nodes creates a link.

See also: IliGrapher.

Accessors\nAccessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods <tt>IlvValueInterface::queryValue()</tt>, <tt>IlvValueInterface::queryValues()</tt>, <tt>IlvValueInterface::changeValue()</tt>, <tt>IlvValueInterface::changeValues()</tt>.\n\n\nThis class inherits the accessors of its superclass \c IlvSCGrapherRectangle and adds the following ones:
