  +--org.omegahat.Graphics.Plots.Examples.Events.TableSelectionHandler

All Implemented Interfaces:

java.util.EventListener, javax.swing.event.ListSelectionListener

public class TableSelectionHandler

extends java.lang.Object

implements javax.swing.event.ListSelectionListener

Example for events using plots, highlighting graphical components in a scatter plot as one selects rows in an associated DataViewer (or generally, a JTable). This listens to the selection model of the table, and loops over the graphical components children in the data region passed to the object and identifies the corresponding components by changing their color by setting the GraphicsParameters for those components. See Events

Field Summary

protected GraphicalContainerInt

dataRegion The data region of a plot containing the children to highlight.

Constructor Summary

TableSelectionHandler(javax.swing.JTable table)
Just specify the table from which the row selections are received.

TableSelectionHandler(javax.swing.JTable table, GraphicalContainerInt dataRegion)
Constructor for specifying the table from which to get selection events and the plotting area to update.

TableSelectionHandler(javax.swing.ListSelectionModel selectionModel)
Lower level constructor which listens to the specified selection model, in contrast with retrieving the model from a JTable.

Method Summary

GraphicalContainerInt	getDataRegion() Accessor for dataRegion field
GraphicalContainerInt	setDataRegion(GraphicalContainerInt value) Accessor for setting dataRegion field
void	valueChanged(javax.swing.event.ListSelectionEvent ev) Event handler triggered when the selection model for the JTable changes that computes which rows are selected and highlights the corresponding children in the graphical container previously specified by dataRegion, finishing by redrawing all the children to update the appearance.
