Example usage for org.jfree.data.datasetextension DatasetSelectionExtension addSelectionChangeListener

Introduction

In this page you can find the example usage for org.jfree.data.datasetextension DatasetSelectionExtension addSelectionChangeListener.

Prototype

public void addSelectionChangeListener(SelectionChangeListener listener);

Source Link

Document

adds a label selection listener to the dataset extension

the listener is triggered if a data item changes its selection state except the notify flag is set to false (@link #setNotify(boolean)).
