public class JUTableBinding

extends JUCtrlRangeBinding

implements javax.swing.table.TableModel, JUPanelStopEditingListener, java.awt.event.HierarchyListener

A lightweight TableModel that implements binding a javax.swing.JTable to a RowIterator for a BC4J ViewObject.

Applications should subclass this binding and return a subclass of JUTableModel that can:

• Perform application-specific sorting of rows displayed in a JTable.
• Dynamically display/hide certain columns based on user preferences or application logic.

This class creates a runtime instance of JUTableModel to interact with a JTable instance. It is responsible for:

• Managing Row and iterator events from BC4J layer and calls appropriate JTableModel methods to update JTable display.
• Manages edits using the current Cell Editor by cancelling/accepting edits from the current cell editor.

Constructor Detail

JUTableBinding

public JUTableBinding(javax.swing.JTable control,
JUIteratorBinding iterBinding,
                      java.lang.String[] attrNames)

Creates an instance of JUTableModel that performs the binding of a BC4J ViewObject with a JTable. This binding class performs the role of an intermediary between the JUTableModel which implements a TableModel to work with the JTable object and the BC4J framework.

This class is responsible for:

• Calculating how many rows to display in a JTable (based on JTable size).
• Reacting to the BC4J row and iterator events to update display and currency.
