What I am doing is writing an application that creates aqua buttons and
saves them as a png to use on a website. So what I am doing is drawing
the cell into the image and then writing the image out, only that the
cell is not drawing how it should be.
Here is the image:

I'm not quite clear now exactly what your goal is. Are you trying to
make a button from a custom image, or are you simply trying to create
and display a standard NSButton programmatically? It sounded
originally like you wanted the latter, but now I'm not so sure.

What I have now done is created a prototype button in IB and made
connections through to them so I can access the cell and the exact

thing is happening when using the cell of a "properly created" button.
For instance, the text is not vertically aligned like it should be
(center) and the key equivalent is not shown, in this case the button
should be blue for "\r".
This is really quite puzzling as there seems to be something not
happening when just drawing the cell.
Here is the code that captures the button cell into an image.
- (NSImage *)btnGenerator:(NSButtonCell *)btn
{
NSSize size = [btn cellSize];
size.width += 2 * [padding floatValue];
NSImage *img = [[NSImage alloc] initWithSize:size];
NSRect frame = NSMakeRect(0,0,size.width, size.height);
[img lockFocus];
[[NSColor clearColor] set];
NSRectFill(frame);
[btn drawWithFrame:frame
inView:nil];
[img unlockFocus];
return [img autorelease];
}
