The problem is, I don't know how to determine to which row that newly-added object corresponds in the table view. Is there any way? I suppose it's the current-selected row, since it's set up to select on add. Is there a more elegant way to find out, though (i.e., what if adding didn't change the selection).How does one find the row in the table view corresponding to any given instance?
Add this to your category on NSTreeController. It calls the - flattendedNodes method I gave you earlier. You can then get the tree node for the whatever you added to the tree and call NSOutlineView's - rowForItem:
- (NSTreeNode *)treeNodeForObject:(id)object;
{
NSTreeNode *treeNode = nil;
for (NSTreeNode *node in [self flattenedNodes]) {
if ([node representedObject] == object) {
treeNode = node;
break;
}
}
return treeNode;
}
