Class IlvGeneralNode

java.lang.Object
  ilog.views.IlvGraphic
      ilog.views.graphic.IlvGraphicSet
          ilog.views.sdm.graphic.IlvGeneralNode

All Implemented Interfaces:: GraphicBagHierarchyEventReceiver, ManagerViewsHierarchyEventReceiver, IlvGraphicBag, IlvLabelInterface, IlvPersistentObject, ilog.views.sdm.internal.labellayout.IlvSDMLabeledNode, Transferable, Serializable

Direct Known Subclasses:: IlvDefaultLaneGraphic, IlvSwimLanesRenderer.DefaultSwimLaneGraphic

public class IlvGeneralNode
extends IlvGraphicSet
implements IlvLabelInterface, ilog.views.sdm.internal.labellayout.IlvSDMLabeledNode
extends IlvGraphicSet
implements IlvLabelInterface, ilog.views.sdm.internal.labellayout.IlvSDMLabeledNode

The class IlvGeneralNode is a general-purpose graphic object with a geometric shape (square, circle, diamond, or similar), a label, and an icon, each being optional.

The label can be zoomable and can become invisible below a given zoom level to avoid overloaded displays. Labels can contain several lines (separated by '\n' characters). The general node supports automatic word wrapping or truncation of the label.

The shape and the icon can be defined as SVG files.

Note: In JViews 6.0, performance and graphic improvements have been made to this class that may introduce slight changes in bounding boxes. See setUseIlvText(boolean) for more details.

Since:: JViews 4.0

realize

protected void realize()

This method creates all the components of the general node. It is called once all the properties have been set, just before the layout is computed.

The realize method first removes all the objects from the graphic set, and re-creates them according to the current properties of the general node. You need to override this method is you want to add new components to the general node.

doLayout

protected void doLayout()

Computes the relative positions and sizes of the different parts of the general node: shape, labels, icon, and decorations. You may need to override this method if you add new graphic objects to the node.

setForeground

public void setForeground(Color c)

Sets the foreground color of the node shape.

Note that this may change the bounding rectangle of the node. For this reason, if the node is contained inside a manager, you should modify the node using the applyToObject method of the manager.

Overrides:: setForeground in class IlvGraphic

Parameters:: c - The new foreground color.

setBackground

public void setBackground(Color c)

Sets the background color of the node shape.

Note that this may change the bounding rectangle of the node. For this reason, if the node is contained inside a manager, you should modify the node using the applyToObject method of the manager.
