/** |
2 |
26 Feb 07 |
jari |
* TableSorter is a decorator for TableModels; adding sorting |
2 |
26 Feb 07 |
jari |
* functionality to a supplied TableModel. TableSorter does |
2 |
26 Feb 07 |
jari |
* not store or copy the data in its TableModel; instead it maintains |
2 |
26 Feb 07 |
jari |
* a map from the row indexes of the view to the row indexes of the |
2 |
26 Feb 07 |
jari |
* model. As requests are made of the sorter (like getValueAt(row, col)) |
2 |
26 Feb 07 |
jari |
* they are passed to the underlying model after the row numbers |
2 |
26 Feb 07 |
jari |
* have been translated via the internal mapping array. This way, |
2 |
26 Feb 07 |
jari |
* the TableSorter appears to hold another copy of the table |
2 |
26 Feb 07 |
jari |
* with the rows in a different order. |
2 |
26 Feb 07 |
jari |
* <p/> |
2 |
26 Feb 07 |
jari |
* TableSorter registers itself as a listener to the underlying model, |
2 |
26 Feb 07 |
jari |
* just as the JTable itself would. Events recieved from the model |
2 |
26 Feb 07 |
jari |
* are examined, sometimes manipulated (typically widened), and then |
2 |
26 Feb 07 |
jari |
* passed on to the TableSorter's listeners (typically the JTable). |
2 |
26 Feb 07 |
jari |
* If a change to the model has invalidated the order of TableSorter's |
2 |
26 Feb 07 |
jari |
* rows, a note of this is made and the sorter will resort the |
2 |
26 Feb 07 |
jari |
* rows the next time a value is requested. |
2 |
26 Feb 07 |
jari |
* <p/> |
2 |
26 Feb 07 |
jari |
* When the tableHeader property is set, either by using the |
2 |
26 Feb 07 |
jari |
* setTableHeader() method or the two argument constructor, the |
2 |
26 Feb 07 |
jari |
* table header may be used as a complete UI for TableSorter. |
2 |
26 Feb 07 |
jari |
* The default renderer of the tableHeader is decorated with a renderer |
2 |
26 Feb 07 |
jari |
* that indicates the sorting status of each column. In addition, |
2 |
26 Feb 07 |
jari |
* a mouse listener is installed with the following behavior: |
2 |
26 Feb 07 |
jari |
* <ul> |
2 |
26 Feb 07 |
jari |
* <li> |
2 |
26 Feb 07 |
jari |
* Mouse-click: Clears the sorting status of all other columns |
2 |
26 Feb 07 |
jari |
* and advances the sorting status of that column through three |
2 |
26 Feb 07 |
jari |
* values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to |
2 |
26 Feb 07 |
jari |
* NOT_SORTED again). |
2 |
26 Feb 07 |
jari |
* <li> |
2 |
26 Feb 07 |
jari |
* SHIFT-mouse-click: Clears the sorting status of all other columns |
2 |
26 Feb 07 |
jari |
* and cycles the sorting status of the column through the same |
2 |
26 Feb 07 |
jari |
* three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}. |
2 |
26 Feb 07 |
jari |
* <li> |
2 |
26 Feb 07 |
jari |
* CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except |
2 |
26 Feb 07 |
jari |
* that the changes to the column do not cancel the statuses of columns |
2 |
26 Feb 07 |
jari |
* that are already sorting - giving a way to initiate a compound |
2 |
26 Feb 07 |
jari |
* sort. |
2 |
26 Feb 07 |
jari |
* </ul> |
2 |
26 Feb 07 |
jari |
* <p/> |
2 |
26 Feb 07 |
jari |
* This is a long overdue rewrite of a class of the same name that |
2 |
26 Feb 07 |
jari |
* first appeared in the swing table demos in 1997. |
