Did you look at the examples in /Developer/Examples/Ruby/MacRuby There a few examples using NSView, I'd be curious to know what's missing. (the yml table example should help) - Matt Sent from my iPhone On Oct 23, 2010, at 6:05, Pixoo <madpixoo@gmail.com> wrote:
Ok it worked \o/ I'm pretty new at ObjC (therefore I use MacRuby :D) so I don't know NS objects.
Thanks again :)

irb(main):007:0> a.removeObjectsAtIndexes(indices) => ["apple", "orange"]
If you find you need to work with NSIndexSet's a lot, you could go to town and add this to NSIndexSet: http://gist.github.com/642166

That doesn't match what I need. Ok, here is what I have :
My data is the @items variable which is an array of objects. My tableView is @tableView. The action is a reaction to a click on a remove button after a selection in the table.
What I want to do is something like this :
def removeItems(sender) indexes = @tableView.selectedRowsIndexes @items.delete_at(indexes) @tableView.reloadData end
But I can't get a way to make it work.

Hi !
I'm trying to use a tableView with MacRuby. What I want to do is remove items from my data array based on the tableView selection.
I used @tableView.selectedRowsIndexes but it returns a NSIndexSet and I don't know how to use it with my array. Can you give me some leads on the subject ?
Thanks,
