title: Adding an NSControl to IKImageBrowserCell
body: <p>I've built a custom IKImageBrowserCell which is displaying my images in an IKImageBrowser without any issues.</p>
  
  <p>I'd like to try and override the built in IKImageBrowser delete image functionality. Currently 'out of the box' you can select an image, or multiple images and press BACKSPACE to delete.</p>
  
  <p>I'd like to add an NSButton or similar to enable that same functionality on each image.</p>
  
  <p>I've added the following code to show a delete icon on the IKImageBrowserCell when it is selected:</p>
  
  <pre><code>- (CALayer *) layerForType:(NSString*) type {
  
  CGColorRef color;
  
  //retrieve some usefull rects
  NSRect frame = [self frame];
  NSRect imageFrame = [self imageFrame];
  NSRect relativeImageFrame = NSMakeRect(imageFrame.origin.x - frame.origin.x, imageFrame.origin.y - frame.origin.y, imageFrame.size.width, imageFrame.size.height);
  
  if(type == IKImageBrowserCellForegroundLayer){
      //no foreground layer on place holders
      if([self cellState] != IKImageStateReady)
          return nil;
  
      //create a foreground layer that will contain several childs layer
      CALayer *layer = [CALayer layer];
      layer.frame = CGRectMake(0, 0, frame.size.width, frame.size.height);
  
  
      if([self isSelected]){
  
          //add a delete icon
          CALayer *deleteLayer = [CALayer layer];
  
          [deleteLayer setContents:(id)deleteImage()];
          deleteLayer.frame = CGRectMake(relativeImageFrame.size.width-14, (relativeImageFrame.origin.y+relativeImageFrame.size.height)-14, 28, 28);
          [layer addSublayer:deleteLayer];
      }
    }
  }
  </code></pre>
  
  <p>This works great, but obviously just a static image. Is there any way I can try and get an event from hitting this delete icon, and then return the selected cell index to the IKImageBrowser in order to call it's removeItemsFromIndex: method ? Am stuck!</p>
