Customising the group row behaviour does seem like the answer here.
The required groupRow view can be defined by calling
- (void)registerNib:(NSNib *)nib forIdentifier:(NSString *)identifier
Then, when
- (NSView *)tableView:(NSTableView *)tableView
viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row
is called it is just a matter of retrieving the group row nib using
- (id)makeViewWithIdentifier:(NSString *)identifier owner:(id)owner
The group row styling will be applied though, which I don’t require.
Rather than having to define a custom NSTableRowView it seems sufficient to
just reset the groupRowStyle on the row view.
- (void)tableView:(NSTableView *)tableView didAddRowView:(NSTableRowView
*)rowView forRow:(NSInteger)row
{
// if a group row has been added then turn off the group styling
// so that group rows are drawn like other rows
if ([self tableView:tableView isGroupRow:row]) {
rowView.groupRowStyle = NO;
}
}
The cell views do get recycled so it is often necessary, especially when
binding to different object types in the one tableview to normalise the
NSTableCellView.
NSTableCellView *cellView = [tableView makeViewWithIdentifier:identifier
owner:nil];
// the cell view may be recycled so normalise it
cellView.objectValue = nil;
[cellView.textField unbind:NSValueBinding];
cellView.textField.stringValue = @"";
