Re: Resizing Buttons with PyGTK / Glade

["Tristan Van Berkom" <tvb gnome org>]

Notebooks map/unmap the pages, pages that have visible=False, or if the
toplevel is invisible, will not be realized at init time, maybe this is causing
grief.

Try making your toplevel visible in Glade or manually realizing your
notebook pages, or possibly calling gtk_container_check_resize() on
the pages when showing them for the first time.

Ummm, then you might move on to check that there isnt a notebook
bug filed for this and file one yourself if there isnt (that part
really helps ;-) )

Cheers,
