Hi,
I have an NSOutlineView showing sources in the same way as iTunes 7,
which 'header rows' for "Places", "Smart Lists", etc.
On opening a new or previous document, I would like the outlineview to
expand all its nodes. I have written the method to do this, and
checked it works by hooking it up as an IBAction. However, when I call
the method from within one of the two initialisation delegates, e.g:
- (void)windowControllerDidLoadNib:(NSWindowController *)windowController
{
...
[sourcesOutlineView expandAllNodes:nil];
}
- (BOOL)configurePersistentStoreCoordinatorForURL:(NSURL *)url
ofType:(NSString *)fileType error:(NSError **)error
{
...
[sourcesOutlineView expandAllNodes:nil];
}
The expansion doesn't occur. I'm guessing this is because the outline
view hasn't by this time been associated to its NSTreeController data
source.
Does anyone know where I could place the -expandAllNodes call so that
it will be triggered after the nib has been loaded and all the data
sources hooked up?
Thanks in advance!
Chris
