| TableSorter | | public class TableSorter extends AbstractTableModel (Code) | | TableSorter is a decorator for TableModels; adding sorting functionality to a
supplied TableModel. TableSorter does not store or copy the data in its
TableModel; instead it maintains a map from the row indexes of the view to
the row indexes of the model. As requests are made of the sorter (like
getValueAt(row, col)) they are passed to the underlying model after the row
numbers have been translated via the internal mapping array. This way, the
TableSorter appears to hold another copy of the table with the rows in a
different order. TableSorter registers itself as a listener to the
underlying model, just as the JTable itself would. Events recieved from the
model are examined, sometimes manipulated (typically widened), and then
passed on to the TableSorter's listeners (typically the JTable). If a change
to the model has invalidated the order of TableSorter's rows, a note of this
is made and the sorter will resort the rows the next time a value is
requested. When the tableHeader property is set, either by using the
setTableHeader() method or the two argument constructor, the table header may
be used as a complete UI for TableSorter. The default renderer of the
tableHeader is decorated with a renderer that indicates the sorting status of
each column. In addition, a mouse listener is installed with the following
behavior:
- Mouse-click: Clears the sorting status of all other columns and advances
the sorting status of that column through three values: {NOT_SORTED,
ASCENDING, DESCENDING} (then back to NOT_SORTED again).
- SHIFT-mouse-click: Clears the sorting status of all other columns and
cycles the sorting status of the column through the same three values, in the
opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
- CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except that
the changes to the column do not cancel the statuses of columns that are
already sorting - giving a way to initiate a compound sort.
This is a long overdue rewrite of a class of the same name that first
appeared in the swing table demos in 1997.
