You may need to use setOutlineTableColumn: method to set the outline
column specifically.

Hi Everyone,
I am trying to create an NSOutlineView programmatically inside of
an NSDrawer. I am using the example datasource from /Developer/
Examples/AppKit/OutlineView the "FileSystemItem".
My issue is that although the root item is displayed in the
OutlineView, it is not expandable and does not show any of the
children. The datasource is identical to the one in the Apple
example so I'm guessing my issue is the way I am creating the
NSOutlineView in code rather than in IB. The result is that I see
an outlineview with one item (the root item) with one table column
header and no expand icons. If anyone can see something I'm doing
wrong I would very much appreciate the help
My code is attached.
Thank you ahead of time!
Zack
NSView *contentView = [win contentView];
[contentView setAutoresizesSubviews:YES];
outlineView = [[NSOutlineView alloc] initWithFrame: [contentView
frame]];
//DataSource. code is attached below
ZBFSDataSource *ds = [[ZBFSDataSource alloc] init];
[outlineView setDataSource: ds];
NSTableColumn *c = [[NSTableColumn alloc] initWithIdentifier:
@"NAME"];
[c setEditable: NO];
[c setMinWidth: 150.0];
[outlineView addTableColumn: c];
[c release];
[outlineView reloadData];
scrollView = [[NSScrollView alloc] initWithFrame: [outlineView
frame]];
[scrollView setDocumentView: outlineView];
[scrollView setAutoresizesSubviews: YES];
NSDrawer *drawer = [[NSDrawer alloc]
initWithContentSize:NSMakeSize(200.0, 400.0)
preferredEdge:NSMinXEdge];
[drawer setParentWindow: win];
[drawer setContentView: scrollView];
[drawer open];
DataSource:
- (NSInteger)outlineView:(NSOutlineView *)outlineView
numberOfChildrenOfItem:(id)item {
return (item == nil) ? 1 : [item numberOfChildren];
}
- (BOOL)outlineView:(NSOutlineView *)outlineView isItemExpandable:
(id)item {
return (item == nil) ? YES : ([item numberOfChildren] != -1);
}
- (id)outlineView:(NSOutlineView *)outlineView child:
(NSInteger)index ofItem:(id)item {
return (item == nil) ? [FileSystemItem rootItem] :
[(FileSystemItem *)item childAtIndex:index];
}
- (id)outlineView:(NSOutlineView *)outlineView
objectValueForTableColumn:(NSTableColumn *)tableColumn byItem:
(id)item {
return (item == nil) ? @"/" : (id)[item relativePath];
}
