Left / right tabs on Gtk::Notebook

[Callum Prentice <gtk callum com>]

i'm experimenting with the tabbed 'notebook' containers and am having a problem with
left/right aligned tabs when i use gtk_rc_parse ( "path/to/rcfile" ); to change the look of my
dialog.

if i pass Gtk::POS_TOP or Gtk::POS_BOTTOM to Gtk::Notebook::set_tab_pos, things work as
expected and the tab changes appearance based on the resource file i loaded.

if i use Gtk::POS_LEFT or Gtk::POS_RIGHT, the tab mechanism itself works - i.e. i can change
pages - but the tabs do not inherit the rest of the gui's visual characteristics.

does anyone know if this is a bug, a limitiation or if i have to make some extra calls to
achieve what i want.

eventually, i'd like the text in the tabs at the left/right side to be vertically oriented but
i can't find any type of set_orientation call in either Gtk::Notebook or Gtk::Label - is this
possible ?

thanks in advance.
