Class PageTableModel

java.lang.Object

javax.swing.table.AbstractTableModel

smile.swing.table.PageTableModel

All Implemented Interfaces:

java.io.Serializable, javax.swing.table.TableModel

public abstract class PageTableModel
extends javax.swing.table.AbstractTableModel

A table model that performs "paging" of its data. This model reports a small number of rows (like 100 or so) as a "page" of data. You can switch pages to view all of the rows as needed using the pageDown() and pageUp() methods. Presumably, access to the other pages of data is dictated by other GUI elements such as up/down buttons, or maybe a text field that allows you to enter the page number you want to display.
