Hi Kyle,
Thanks for the assist, I have attempted to use childNodes (see the following
code) and it works out fine ONLY the parent node itself also gets removed...
Here's what I did:
int parentId = 1; //Some node I wanna empty
[treeController setSelectionIndexPath:[NSIndexPath
indexPathWithIndex:parentId]];
NSTreeNode *node = [[treeController selectedNodes] objectAtIndex: 0];
NSMutableArray * ip = [[NSMutableArray alloc] init];
NSArray * nodes = [node childNodes];
// if I start i at 0, the "enclosing" node also gets removed.
// Setting it at 1 doesn't remove it (and sucessfully removes the children).
// I don't get this, I thought I was dealing with only children?
for(int i=1; i<=[nodes count]; i++){
[ip addObject:[[nodes objectAtIndex:0] indexPath]];
}
[treeController removeObjectsAtArrangedObjectIndexPaths:ip];
Any thoughts?
