I want to customise the appearance of a selected cell in an IKImageBrowserView.
I'm subclassing IKIMageBrowserView, and overriding:
- (IKImageBrowserCell*) newCellForRepresentedItem:(id) anItem
{
IKImageBrowserCell* cell = [super newCellForRepresentedItem:anItem];
// set up the selection highlight colour by changing the layer
characteristics
CALayer* selLayer = [cell
layerForType:IKImageBrowserCellForegroundLayer];
selLayer.borderWidth = 1.0;
selLayer.backgroundColor = [[NSColor greenColor] CGColor];
return cell;
}
(the appearance isn't what I want, but this is just to see if it works).
The layer returned by -layerForType: is nil, and it is nil for all of the
possible layer types. I also tried setting this when the selection changes in
the delegate callback, but these layers are always nil. The cell is valid.
Has anyone managed to get this to work?
