BuddyPress.org

I am fairly new to wordpress & buddypress. I wanted to know how can I display separate tabs for public,private & hidden groups for users in the groups section, where all groups are displayed. There is a function bp_get_total_group_count() for getting the total group count for a particular user, but no function to determine which type of group it is (i.e public, private or hidden). Might have to use some apply_filter thing, but am not sure. Please help. I can provide you with the code, if required. Thanks.
