The column selection control is a list box of column names with

selection indicating which Columns to Copy. Use the standard

Windows selection mechanism of shift-click to select a range of items

and ctrl-click to change the selection state of a single item.

The standard property dialogs used in Spotfire Miner are singletons.

There is only a single dialog of each type that is reused. This reduces

the memory usage and the time needed to display the dialog. A

ramification of this is that the state of the dialog is not reset when it is

closed. Any initialization to the dialog needs to be done when the

dialog is restored.

The key methods for setting and getting the properties are

restoreProperties() and saveProperties(). The constructor and

getInstance() methods are boilerplate routines, and the

createOptionsPanel() method defines the first page of the dialog.

We override the

onHelp() method to launch a message box with

some help information. While it’s preferable to display a more

descriptive external help file, we use the message box to keep the

example self-contained.

The file

ThirdCopyDialog.java contains:

import com.insightful.miner.*;

import javax.swing.*;

import java.awt.*;

import java.util.Vector;

public class ThirdCopyDialog extends NodeDialog {

// Static instance of the dialog

private static ThirdCopyDialog instance = null;

// Controls

private JList listBox;

private DefaultListModel listModel;

public static ThirdCopyDialog getInstance() {

if (instance == null) {

instance = new ThirdCopyDialog();

}

return(instance);

}
