Subject Re: Sort a column in a TableView with only image in the column cell.
Date Wed, 07 Jul 2010 19:01:15 GMT
Another approach is to actually store sortable data in the column (such as an image file name
or some sort of status value) but use a custom renderer to present that data as an image.

use the Comparable.compareTo(Object) method if the object implement Compare. If not, it use
the toString() method that use the hash code of the object to sort. So, the hash code change
for the object at each execution and it change the sort order as well at each execution.

you have some clue to do it? If not that could be an nice thing to add in the next version
