group buttons

[Leen Toelen <leen toelen cropdesign com>]

Hi,

I am trying to figure out if it is possible to group some buttons in gtk 
together. In Aqua this is possible, eg safari uses it for the back/next 
buttons, and iCal for the back/day/week/month/next. This works by 
cutting the edges off the middle buttons, and only showing those at the 
ends of the groups. The results is that those buttons are visually bound 
to each other. I find this much more elegant than the current evolution 
setup, and would love to use this in gtk as well.

Thanks,
