Hello,

does anybody know how the new features for Table sorting work.
I can't find any good information how to achieve this!

Here is what I am trying to do:
I have a tableView including a checkbox column, a text column and a popupmenu column. now when i click on the column header i want to sort the data in the tableView.
Can anybody please roughly explain how this would work. How can I use the NSSortDescriptor to sort? Why are there options for this in Interface Builder and how do they work? I am really confused, because in my opinion Apple doesn't provide enough documentation and/or examples on this topic.

Sincerely,
rudy norff

I now get how to use the new NSSortDescriptor stuff. I implemented the following code:

- (void)tableView:(NSTableView *)tableView sortDescriptorsDidChange:(NSArray *)oldSortDescriptors {
// arTasks is my Mutable Array
[arTasks sortUsingDescriptors: [tableView sortDescriptors]];
[self saveData]; // this just saves my array into a plist
[tableView reloadData];
}

The sorting works for all columns containing text. But when I select a column with the content being a number (I have some Popupmenus in my table) or when I select the column that contains booleans (I have checkboxes in that column) then it just says something like this:

[NSFCBoolean length]: selector not recognized

Does anybody have an idea wy this is happening? By the way: for every column I used the sort selector compare: in interface builder, this should work, right?

thanks for your answers in advance!
