All Implemented Interfaces:

Comparable

public class IVNode
extends TNode
implements Comparable

Extends TNode as an alternative display mode for Topics. The name is a legacy of now-gone GraphView subclass and will be changed when this is re-integrated into the GraphView. This includes a target and rectangular boundary mode.

Since:

JDK1.4

Constructor Detail

IVNode

public IVNode(String id)
       throws GraphException

Constructor with the required ID id value. If this IVNode is meant to correspond to an XTM topic, its ID should match the ID of the topic.

Throws:

GraphException

IVNode

public IVNode(String id,
              String label)
       throws GraphException

Constructor with the required ID id and label. If this IVNode is meant to correspond to an XTM topic, its ID should match the ID of the topic, though this is not enforced here.

Throws:

GraphException

IVNode

public IVNode(Topic topic)
       throws GraphException

Constructor with an Topic topic, using the Topic's ID value for both the IVNode's ID and label.

Throws:

GraphException

IVNode

public IVNode(Topic topic,
              String label)
       throws GraphException

Constructor with an Topic topic, and a String used as its label. The ID of the IVNode will be obtained from the Topic object.

Throws:

GraphException

IVNode

public IVNode(Topic topic,
              String id,
              String label)
       throws GraphException

Constructor with an Topic topic and Strings for ID id and label.

Throws:

GraphException

Method Detail

getTargetLocation

protected Point getTargetLocation()

Returns the location of the target's center as a Point. Note that the node center and the target center are not the same. If the FontMetrics are unavailable, returns the superclass' getLocation() value.

setSize

protected void setSize(Graphics g)

Sets the internal width and height variables based on current properties.

Overrides:

setSize in class GraphNode

getWidth

public int getWidth()

Overrides GraphNode's method by returning the calculated width of this IVNode. This also sets bw, which sets the size of the target node area.

Overrides:

getWidth in class TNode

paintNodeBody

public void paintNodeBody(Graphics g,
                          TGPanel tgPanel)

Overrides TNode's method by painting the body of the IVNode.

Overrides:

paintNodeBody in class TNode

getTargetBorderColor

public Color getTargetBorderColor(TGPanel tgPanel)

Returns the border color of the target, dependent on context.

getNodeBodyColor

public Color getNodeBodyColor(TGPanel tgPanel)

Returns the body color of the node, dependent on context.

getPaintBackColor

public Color getPaintBackColor(TGPanel tgPanel)

Overrides TNode's method.

Overrides:

getPaintBackColor in class TNode
