It seems like the best solution would be to handle both the Leopard+
and pre-Leopard cases at runtime so any changes to HID over time are
non-issues since you've limited the custom code to the pre-Leopard
case. You might be able to get away with as little as adding a
category to NSCell (typed in Mail so this hasn't been tested):
@implementation NSCell (MyRaisedBackgroundStyle)
- (void)useRaisedBackgroundStyle
{
#if MAC_OS_X_VERSION_MIN_REQUIRED < MAC_OS_X_VERSION_10_5
if (floor(NSAppKitVersionNumber) <= NSAppKitVersionNumber10_4)
{
NSMutableAttributedString* text =
[[[NSMutableAttributedString alloc] initWithAttributedString:
[self attributedStringValue]] autorelease];
NSShadow* shadow = [[[NSShadow alloc] init] autorelease];
[shadow setShadowColor:[NSColor colorWithCalibratedWhite:1.0
alpha:0.5]];
[shadow setShadowOffset:NSMakeSize(0.0, -1.5)];
[shadow setShadowBlurRadius:0.0];
[text addAttribute:NSShadowAttributeName value:shadow
range:NSMakeRange(0, [text length])];
[self setAttributedStringValue:text];
}
else
#endif
{
[self setBackgroundStyle:NSBackgroundStyleRaised];
}
}
@end
You'd need to call this method after the cell's text has been
initialized/modified, which could just be done in -awakeFromNib for
static text. If you wanted to get fancy, you could write a custom
cell class that does all of the above whenever any of the text
attributes are changed.

Yes, I'm sure. :-) You won't get the subpixel font smoothing right, if
nothing else.
Also, the other method tracks whatever the current human interface
design is
for text on a raised surface.

This effect cannot be implemented with text attributes.
Are you sure? This gets awfully close, unless I'm missing the
point here
(the font to use your choice):
+ (NSDictionary*) defaultTitleAttributes
{
// return the dictionary used to specify the attributes for
drawing
the title string in the palette windows. Override to
// customize the title string
static NSDictionary* sTitleAttrs = nil;
if ( sTitleAttrs == nil )
{
NSFont* font = [NSFont boldSystemFontOfSize:11.0];
NSMutableParagraphStyle* style = [[NSParagraphStyle
defaultParagraphStyle] mutableCopy];
[style setAlignment:NSCenterTextAlignment];
NSShadow* shadw = [[NSShadow alloc] init];
[shadw setShadowColor:[NSColor whiteColor]];
[shadw setShadowOffset:NSMakeSize( 0, -1.5 )];
[shadw setShadowBlurRadius:1.0];
sTitleAttrs = [NSDictionary
dictionaryWithObjectsAndKeys:font,NSFontAttributeName,
style,NSParagraphStyleAttributeName,
shadw, NSShadowAttributeName,
nil];
[sTitleAttrs retain];
[style release];
[shadw release];
}
return sTitleAttrs;
}
