SortDelegate example?

[Val]

Dear everyone,
I am wondering if anyone would be willing to provide a working
SortDelegate example.
As it stands now, it is really unclear to me how this method should
work.
Thanks in advance!

Hi Val,

The SortDelegate should simply trigger your sorting code. For example if you were using Glazed Lists, then your SortDelegate would install a new Comparator with the sort criteria on your SortedList.

In that case the delegate might look something like this:

TableUtils.SortDelegate sortDelegate = new TableUtils.SortDelegate() {

        public void sort(int columnModelIndex, TableUtils.SortDirection sortDirection) {

            mySortedList.setComparator(...);
        }

    };

See this example as well:

Hi,

for GalzedLists and the ITunes Table, I find something like this quiet usefull:

TableUtils.makeSortable(table, new TableUtils.SortDelegate() {
    public void sort(int i, TableUtils.SortDirection sortDirection) {
        if(sortDirection == TableUtils.SortDirection.DESCENDING){
            sorted.setComparator(new InverseComparator(new TableColumnComparator(format, i)));                  
        }else{
            sorted.setComparator(new TableColumnComparator(format, i));
        }       
    }
});

TableColumnComparator is ca.odell.glazedlists.impl.sort.TableColumnComparator. This way I can use the ITunes table the same way I use any other table based on an EventTableModel, and custom comparators can be installed on the TableFormat.
