Re: EventListJXTableSorting

[Holger Brands]

Boomah,

The latest build available here
https://glazedlists.dev.java.net/servlets/ProjectDocumentList?folderID=3916&expandFolder=3916&folderID=3916
contains a new install method
EventListJXTableSorting#install(JXTable, SortedList, Comparator)
where you can specify a default comparator
which will be used when there are no sort keys.

In your example you would use
EventListJXTableSorting.install(imageTable, sortedList, sortedList.getComparator());
to get the desired effect.

Hope this helps,
Holger
