PipeAlgorithmGroupView

public static class PipeAlgorithmGroupView.ActivityRenderer
extends VertexRenderer

The Class ActivityRenderer.

Field Summary

protected java.awt.Color	graphForeground Holds the background and foreground of the graph.
static java.awt.Rectangle	handle Default handle bounds for renderer, '+' or '-'.
protected java.awt.Color	handleColor Holds the background and foreground of the graph.
protected boolean	isGroup Specifies whether the current view is a rich text value, and if the image should be stretched.

Constructor Summary

PipeAlgorithmGroupView.ActivityRenderer()

Method Summary

java.awt.Dimension	getPreferredSize() Return a slightly larger preferred size than for a rectangle.
java.awt.Component	getRendererComponent(JGraph graph, CellView view, boolean sel, boolean focus, boolean preview) Overrides the parent implementation to return the value component stored in the user object instead of this renderer if a value component exists.
boolean	inHitRegion(java.awt.geom.Point2D pt) Detect whether or not a point has hit the group/ungroup image.

Method Detail

getPreferredSize

public java.awt.Dimension getPreferredSize()

Return a slightly larger preferred size than for a rectangle.

Returns:

the preferred size

getRendererComponent

public java.awt.Component getRendererComponent(JGraph graph,
                                               CellView view,
                                               boolean sel,
                                               boolean focus,
                                               boolean preview)

Overrides the parent implementation to return the value component stored in the user object instead of this renderer if a value component exists. This applies some of the values installed to this renderer to the value component (border, opaque) if the latter is a JComponent.

Parameters:

graph - the graph

view - the view

sel - the sel

focus - the focus

preview - the preview

Returns:

Returns a configured renderer for the specified view.

inHitRegion

public boolean inHitRegion(java.awt.geom.Point2D pt)

Detect whether or not a point has hit the group/ungroup image.

Parameters:

pt - the point to check

Returns:

whether or not the point lies within the handle

paint

public void paint(java.awt.Graphics g)
