ILOG JViews Diagrammer comes with a set of classes designed to ease the development of Swing GUIs containing one or more IlvDiagrammer objects. These classes are contained in the package ilog.views.diagrammer.application.

The class IlvDiagrammerAction is a base class for Swing Actions that act on an IlvDiagrammer object. A set of predefined actions that call the main IlvDiagrammer methods is provided.

The class IlvDiagrammerToolBar is a Swing JToolBar that accepts a set of IlvDiagrammerAction instances. The subclasses IlvDiagrammerViewBar, IlvDiagrammerEditBar have predefined actions to control and edit the diagram.

The class IlvDiagrammerPaletteBar is designed to be used for editing diagrams. You can populate it with actions that create new nodes and links according to a set of sample objects.

The class IlvDiagrammerMenu is a Swing JMenu that accepts a set of IlvDiagrammerAction instances. The subclasses IlvDiagrammerFileMenu, IlvDiagrammerEditMenu, IlvDiagrammerOptionsMenu and IlvDiagrammerHelpMenu have predefined actions to control and edit the diagram, and to set options and give access to Help for the application. The class IlvDiagrammerMenuBar is a complete predefined menu bar containing all the predefined menus.

The class IlvDiagrammerOverview displays a reduced view of a diagram. You can use it with the zoom facility of a diagram component to control which part of a large diagram is visible.

The class IlvDiagrammerTree is a Swing JTree that displays the nodes and links contained in the diagram's data model. The tree is an alternative way to view and select the objects in the diagram.

The class IlvDiagrammerPropertySheet is a Swing JTable that displays the properties of the selected object of the diagram. Use the property sheet to view and edit the properties of the objects in the data model.

The class IlvDiagrammerTable is a Swing JTable that displays the properties of all the objects in the diagram. Use it to have a global view of the data model.

The class IlvDiagrammerApplication is a complete Swing application that is built using the components in the Application package. This class lets you view (and optionally edit) one or more diagrams. Code Sample 1.9 shows how to launch the application by invoking the java command on this class.

java ilog.views.diagrammer.application.IlvDiagrammerApplication

Code Sample 1.10 shows how to customize a tree, a property sheet, and a table.

Diagrammer {
  styleApplicationComponents : "true"; // enable styling of 
                                          // components.
}
DiagrammerTree {
  rootLabel : "My Graph"; // set label of root item in tree
}
node:DiagrammerTree {
  text : "@name"; // use "name" property as label of items in tree
}
node:DiagrammerPropertySheet:type {
  editable : "false"; // set "type"  property for all nodes read-only
}
node.activity:DiagrammerTable {
  background : "yellow"; // set yellow background for "activity" nodes 
                            // in table 
}
