Creating NSMatrix programmatically, Snow Leopard

Question

I am trying to create an NSMatrix prototype of NSImageCell programmatically (if you can help me do this through Interface Builder, be my guest by answering me here )

I created a new empty project. In it, a regular object (subclassification of NSObject) has this code (and only this code):

- (void) awakeFromNib {
    NSRect f = view.bounds;
    NSMatrix* matrix = [[NSMatrix alloc] initWithFrame:f mode:NSListModeMatrix cellClass:[NSImageCell class] numberOfRows:1 numberOfColumns:1];

    [matrix setCellSize:NSMakeSize(100, 100)];
    [matrix sizeToCells];
    [matrix setNeedsDisplay:YES];

    [view addSubview:[matrix autorelease]];

    [view setNeedsDisplay:YES];

    NSLog(@"Matrix frame: %@", NSStringFromRect(matrix.frame));
}

"view" is an NSView specified as an output connected to a view of the contents of a window in the interface builder.

The matrix is ​​not displayed at all. It prints for logging that frame size (0,0,100,100), as expected.

What am I doing wrong?

As the title says, I am doing this on a Snow Leopard machine using Xcode 3.2.1.

NSMatrix , NSCells . , NSMatrix , .

[matrix setBackgroundColor:[NSColor blueColor]];
[matrix setDrawsBackground:YES];

NSMatrix NSCell, - . , , , .

NSImageCell *cell = (NSImageCell *)[matrix cellAtRow:0 column:0];
[cell setImage:[NSImage imageNamed:@"image.jpg"]];
