Adding NSControl to IKImageBrowserCell

Question

I created a custom IKImageBrowserCell that displays my images in IKImageBrowser without any problems.

I would like to try to override the IKImageBrowser built-in function to delete images. Currently, out of the box you can select an image or several images and press BACKSPACE to delete.

I would like to add NSButton or similar to enable the same functionality on every image.

I added the following code to show the delete icon on IKImageBrowserCell when it is selected:

- (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];
    }
  }
}
