Let's see...
Back in the NeXTSTEP days, I hacked the Box class to replace its
titleCell with a button cell.
@interface NSBox : NSView
{
/*All instance variables are private*/
id _titleCell;
id _contentView;
NSSize _offsets;
NSRect _borderRect;
NSRect _titleRect;
struct __bFlags {
NSBorderType borderType:2;
NSTitlePosition titlePosition:3;
unsigned int transparent:1;
unsigned int boxType:2;
unsigned int _RESERVED:24;
} _bFlags;
id _unused;
}
Yep, there it is: first ivar. So, using the magic of categories:
@interface NSBox (titleCellHack)
- (void) setTitleCell:(NSCell *) aCell
@end
@implementation NSBox (titleCellHack)
- (void) setTitleCell:(NSCell *) aCell
{
if (aCell && (_titleCell != aCell))
[_titleCell release];
[_aCell retain];
_titleCell = aCell;
}
@end
Doing this within IB is left as an exercise for the reader ;-)
IMNSHO, there *should* be a -setTitleCell: method in the public API for
NSBox.

Heh, I have to confess that I cheated to do this in one of my apps... I
simply filled in
the box title with spaces, then lined up the checkbox and its title in
that space. Not
the best way to do it, but I asked the same question a while ago on a
different list, and
got zero response.
