hbox autowrap?

["Scott." <scottf scs unr edu>]

what i need is some sort of container packs widgets into it horizontally,
and if the next widget won't fix in the current viewport, it wraps to the
next line... 

is there such a mechanism built into gtk now? currently, i'm using a
scrolled window with a table inside, but the downside is if you resize the
window, the buttons in the table won't update to fit the most buttons that
can be viewed into the same row... additionally, removing one of the
buttons will leave a blank space in that cell... :(

i'm thinking of something using a hbox (takes care of not leaving blank
spaces when button is removed), but that won't wrap to the current
viewport in the scrolled window...

any ideas?... :)

thanx..
