public class TableComparatorChooser<E>
extends AbstractTableComparatorChooser<E>

A TableComparatorChooser is a tool that allows the user to sort a ListTable by clicking on the table's headers. It requires that the JTables model is an EventTableModel with a SortedList as a source.

This class includes custom arrow icons that indicate the sort order. The icons used are chosen based on the current Swing look and feel. Icons are available for the following look and feels: Mac OS X, Metal, Windows.

This class supports multiple sort strategies for each column, specified by having muliple comparators for each column. This may be useful when you want to sort a single column in either of two ways. For example, when sorting movie names, "The Phantom Menace" may be sorted under "T" for "The", or "P" for "Phantom".

This class supports sorting multiple columns simultaneously. In this mode, the user clicks a first column to sort by, and then the user clicks subsequent columns. The list is sorted by the first column and ties are broken by the second column.

If the EventTableModel uses a AdvancedTableFormat, its AdvancedTableFormat.getColumnComparator(int) method will be used to populate the initial column Comparators.

Constructor Detail

TableComparatorChooser

public TableComparatorChooser(JTable table,
                              SortedList<E> sortedList,
                              boolean multipleColumnSort)

Creates a new TableComparatorChooser that responds to clicks on the specified table and uses them to sort the specified list.

Parameters:

table - the table with headers that can be clicked on

sortedList - the sorted list to update

multipleColumnSort - true to sort by multiple columns at a time, or false to sort by a single column. Although sorting by multiple columns is more powerful, the user interface is not as simple and this strategy should only be used where necessary.

TableComparatorChooser

public TableComparatorChooser(JTable table,
                              SortedList<E> sortedList,
                              Object strategy)

Creates a new TableComparatorChooser that responds to clicks on the specified table and uses them to sort the specified list by delegating to the given strategy.

Parameters:

table - the table with headers that can be clicked on

sortedList - the sorted list to update

strategy - an implementations of SortingStrategy, typically one of

• AbstractTableComparatorChooser.SINGLE_COLUMN
• AbstractTableComparatorChooser.MULTIPLE_COLUMN_MOUSE
• AbstractTableComparatorChooser.MULTIPLE_COLUMN_KEYBOARD

Method Detail

addSortActionListener

public void addSortActionListener(ActionListener sortActionListener)

Registers the specified ActionListener to receive notification whenever the JTable is sorted by this TableComparatorChooser.

removeSortActionListener

public void removeSortActionListener(ActionListener sortActionListener)

Deregisters the specified ActionListener to no longer receive action events.

redetectComparator

protected void redetectComparator(Comparator<? super E> currentComparator)

Examines the current Comparator of the SortedList and adds icons to the table header renderers in response.

To do this, clicks are injected into each of the corresponding ColumnClickTrackers.

Overrides:

redetectComparator in class AbstractTableComparatorChooser<E>

rebuildComparator

protected final void rebuildComparator()

Updates the comparator in use and applies it to the table.

Overrides:

rebuildComparator in class AbstractTableComparatorChooser<E>

getSortingStyle

protected final int getSortingStyle(int column)

Gets the sorting style currently applied to the specified column.

Overrides:

getSortingStyle in class AbstractTableComparatorChooser<E>

isSortingMouseEvent

protected boolean isSortingMouseEvent(MouseEvent e)

Determines if the specified mouse event shall be handled by this TableComparatorChooser. The default implementation handles only clicks with the left mouse button. Extending classes can customize which mouse events the table comparator chooser responds to by overriding this method.

As of 2005/12/20, that this method is no longer called when the corresponding mouse press event was a popup trigger. In effect, if this is a right-click on Windows or a 'control-click' on the Mac.

setIconPath

public static void setIconPath(String path)

Set all TableComparatorChoosers to use the icons from the directory specified. The folder should contain the following eight icon files:

primary_sorted.png

secondary_sorted.png

primary_sorted_alternate.png

secondary_sorted_alternate.png

primary_sorted_alternate_reverse.png

secondary_sorted_alternate_reverse.png

primary_sorted_reverse.png

secondary_sorted_reverse.png

Note that this path must be on the system classpath. It may be within a jar file.

dispose

public void dispose()

Releases the resources consumed by this TableComparatorChooser so that it may eventually be garbage collected.

A TableComparatorChooser will be garbage collected without a call to dispose(), but not before its source EventList is garbage collected. By calling dispose(), you allow the TableComparatorChooser to be garbage collected before its source EventList. This is necessary for situations where an TableComparatorChooser is short-lived but its source EventList is long-lived.

Warning: It is an error to call any method on a TableComparatorChooser after it has been disposed.

Overrides:

dispose in class AbstractTableComparatorChooser<E>
