This is the code I use:

overflowButton = [[NSPopUpButton alloc] initWithFrame:NSMakeRect(0, 0, 17,
10) pullsDown:YES];
[overflowButton setBordered:NO];
[[overflowButton cell] setArrowPosition:NSPopUpNoArrow];
[[overflowButton cell] setAltersStateOfSelectedItem:NO];
[[overflowButton cell] setBackgroundStyle:NSBackgroundStyleRaised];
[overflowButton addItemWithTitle:@""];
[[overflowButton itemAtIndex:0] setImage:[NSImage imageNamed:@"Overflow"]];

Though I've used several other variations without any change in behavior.
