16.7 Getting Down to Cases: Designing a GUI for BudgetPro369Table 16.1 AbstractTableModel methods for data change notificationMethodfireTableCellUpdated(int row, int col)fireTableRowsUpdated(int first, int last)fireTableRowsDeleted(int first, int last)fireTableRowsInserted(int first, int last)fireTableDataChanged()fireTableStructureChanged()fireTableChanged(TableModelEvent e)When to useUse when only a single cell haschanged.Use when the given range of rows(inclusive) have changed.Use when the given range of rows(inclusive) have been deleted.Use when the given range of rows(inclusive) have been inserted.Use when any/all of the row datahave changed, including thenumber of rows; columns havenot changed.Use when the columns havechanged—that is, when thenames, number, or types ofcolumns have changed.An all purpose method, whereyou have to define the change inthe TableModelEvent object.table.getTableHeader().setResizingAllowed(false);table.getTableHeader().setReorderingAllowed(false);The call is not made on the table directly, but rather on its header. We getthe JTableHeader object with the call to getTableHeader(). There is muchmore that could be said about JTableHeader objects, but we will leave that“as an exercise for the reader”; we’ve got to draw the line somewhere.16.7.2.12 ScrollingOne last thing to mention about the createList() method is how we dealwith tables that are larger than the viewing area. This is typically done with ascroll pane, a GUI element familiar to anyone who has used a word processingprogram. Such scrolling is accomplished in Swing by putting the potentiallybig object, such as our table, into a JScrollPane container.
