Re: NSToolbar in Preferences Panel

Thanks. Actually I had all of them (label, icon etc) set  for each
toolbar item in my original code. I was trying out different things and
forgot to include it in the posted code. I think the problem was that
my NSToolbar delegate  methods were not included in the header file and
some of the images  are missing from the nib file. Thanks for pointing
this out. I really appreciate it.
