Hi Ralph,
Here's my code from an NSOutlineView subclass
- (NSArray *)expandedItems;
{
NSMutableArray *expandedItemsArray = [NSMutableArray array];
NSUInteger row, numberOfRows = [self numberOfRows];
for (row = 0 ; row < numberOfRows ; row++)
{
id item = [self itemAtRow:row];
if ([self isItemExpanded:item])
[expandedItemsArray addObject:[item representedObject]]; // create
an array of only the expanded items in the list
}
return [[expandedItemsArray copy] autorelease];
}
The returned array can then be archived.
It uses NSTreeNode and -representedObject, so is 10.5 only. For 10.4
there is an undocumented method for the private class that
NSTreeController used in 10.4 that does the same thing, can't remember
the method name but it's on Scott Stevenson's blog somewhere, just
Google theococoa.com and NSTreeController.
Passing the (now unarchived) array to the method below will expand
them again.
- (void)expandItems:(NSArray *)array;
{
NSUInteger row, numberOfRows = [self numberOfRows];
for (MyNode *savedItem in array) {
for (row = 0 ; row < numberOfRows ; row++) {
id item = [self itemAtRow:row];
MyNode *realObject = [item representedObject];
if ([realObject.nodeName
isEqualToString:savedItem.nodeName]) {
[self expandItem:item];
numberOfRows = [self numberOfRows];
break;
}
}
}
}
Enjoy,
Jon
