I have been studying NSView and as such I thought I would give a shot at a screen saver. I have been able to display and image in an NSView but I can't seen to modify this example code to display a simple picture in ScreenSaverView.

BTW great tutorial that works with Snow Leopard.

I would think to simply display an image I would need something that looked like this...

What am I doing wrong?

    //
//  try_screensaverView.m
//  try screensaver
//


#import "try_screensaverView.h"


@implementation try_screensaverView

- (id)initWithFrame:(NSRect)frame isPreview:(BOOL)isPreview
{
    self = [super initWithFrame:frame isPreview:isPreview];
    if (self) {
        [self setAnimationTimeInterval:1]; //refresh once per sec
    }
    return self;
}

- (void)startAnimation
{


    [super startAnimation];

    NSString *path = [[NSBundle mainBundle] pathForResource:@"leaf" ofType:@"JPG" inDirectory:@""];
    image = [[NSImage alloc] initWithContentsOfFile:path];

}

- (void)stopAnimation
{
    [super stopAnimation];
}

- (void)drawRect:(NSRect)rect
{

    [super drawRect:rect];

}

- (void)animateOneFrame
{


    //////////////////////////////////////////////////////////
    //load image and display  This does not scale the image

    NSRect bounds = [self bounds];
    NSSize newSize;
    newSize.width = bounds.size.width;
    newSize.height = bounds.size.height;
    [image setSize:newSize];
    NSRect imageRect;
    imageRect.origin = NSZeroPoint;
    imageRect.size = [image size];
    NSRect drawingRect = imageRect;
    [image drawInRect:drawingRect fromRect:imageRect operation:NSCompositeSourceOver fraction:1];


}

- (BOOL)hasConfigureSheet
{
    return NO;
}

- (NSWindow*)configureSheet
{
    return nil;
}
