Auto sorting JTable by second column

[d3n1s]

Hello all

I am building a program that displays files and folders from a specific folder on my drive using a JTable component. I have created a custom renderer to show jlabel components with images and it's all working great. I also created a custom comparator class that does exactly what i want when i press on the table header. The issue is that i cannot find how to simulate a user clicking on the second column. It always defaults to the first one and i've been searching for days for a solution. Here's one i found on the oracle page and even that doesn't work :

TableRowSorter sorter = new TableRowSorter(getModel());
Comparator comp = new FolderTableSorter(false);
sorter.setComparator(0, comp);
sorter.setComparator(1, comp);
sorter.setComparator(2, comp);
List<RowSorter.SortKey> sortKeys = new ArrayList<RowSorter.SortKey>();
sortKeys.add(new RowSorter.SortKey(1, SortOrder.DESCENDING));
sorter.setSortKeys(sortKeys);
sorter.toggleSortOrder(1);
setRowSorter(sorter);
((FolderTableModel)getModel()).fireTableDataChange d();
revalidate();

As you can see i tried all sorts of methods that i thought MIGHT update the table lol. The odd thing is calling togglesortorder actually puts a little triangle in the column header but it doesn't update the table. By the way, this is all hapenning in a JTable subclass with internal nested classes for the renderer and what not.

Any help would be appreciated!

bump, Anyone?

Posting a SSCCE might help. If the problem is with the sorting a small table with strings should be enough.

I need a custom renderer to display comboboxes, images, buttons and all kinds of stuff in the cells. I'm doing something on the scale of explorer basically.

I'm not sure what more you want besides this code example. The table sorting is working perfectly fine except it sorts it by default by the first column and i want it to sort the second column by default. Manually pressing the column header works great. I would just like to simlulate someone pressing the second table header upon startup.

So nobody knows how to simulate clicking on the second column header without clicking on it?
