Class JGraphIconView

java.lang.Object
  org.jgraph.graph.AbstractCellView
      org.jgraph.graph.VertexView
          org.jgraph.example.JGraphIconView

All Implemented Interfaces:

java.io.Serializable, org.jgraph.graph.CellView

public class JGraphIconView
extends org.jgraph.graph.VertexView

The cell view modifies the center point of the vertex such that it is relative to the icon rather than the entire vertex. The perimeter

Constructor Summary

Method Summary

java.awt.geom.Point2D	getCenterPoint() The center point of the vertex should be in the middle of the icon instead of the middle of the icon/description duo.
org.jgraph.graph.GraphCellEditor	getEditor()
java.awt.geom.Point2D	getPerimeterPoint(java.awt.geom.Point2D source, java.awt.geom.Point2D p) We don't want to calculate a perimeter point around the entire vertex.
org.jgraph.graph.CellViewRenderer	getRenderer()
boolean	isMouseOver() The mouse over boolean is here so that we could potentially render the icon differently when the mouse is hovering above the vertex.
void	setMouseOver(boolean isMouseOver)

public JGraphIconView()

JGraphIconView

public JGraphIconView(java.lang.Object cell)

Method Detail

getEditor

public org.jgraph.graph.GraphCellEditor getEditor()

Specified by:

getEditor in interface org.jgraph.graph.CellView

Overrides:

getEditor in class org.jgraph.graph.AbstractCellView

isMouseOver

public boolean isMouseOver()

The mouse over boolean is here so that we could potentially render the icon differently when the mouse is hovering above the vertex.

Returns:

whether or not the mouse is over the vertex

setMouseOver

public void setMouseOver(boolean isMouseOver)

getCenterPoint

public java.awt.geom.Point2D getCenterPoint()

The center point of the vertex should be in the middle of the icon instead of the middle of the icon/description duo. The reason we must calculate this is so that edges know where to point. We want to make the edges look like they are pointing to an icon from an icon.

Overrides:

getCenterPoint in class org.jgraph.graph.VertexView

getPerimeterPoint

public java.awt.geom.Point2D getPerimeterPoint(java.awt.geom.Point2D source,
                                               java.awt.geom.Point2D p)

We don't want to calculate a perimeter point around the entire vertex. Only the perimeter around the icon will be calculated. This calculation is generic for elliptical perimeters.

Overrides:

getPerimeterPoint in class org.jgraph.graph.VertexView

getRenderer

public org.jgraph.graph.CellViewRenderer getRenderer()

Overrides:

getRenderer in class org.jgraph.graph.VertexView
