Forum: Ruby-Gnome 2 Gtk Notebook "change-current-page" doesn't work

Hi, i am using gtk notebook. I need to if user change current page, some
button should be active. But current-page-change doesn't work, so
nothing happens. I tried "switch-page" signal but it gives me previous
page number when i asked "notebook.page". But i need to if user change
current page, i should know which page is selected.

Look at the doc page:

http://developer.gnome.org/gtk2/2.24/GtkNotebook.h...

When you intercept "switch-page", you are returned the new page as
second parameter, and the progressive number of the new page as third
parameter.

If nb is your notebook, you write

nb.signal_connect("switch_page") do |a,b,c|
  ...
end

b is the newly selected page, and and c is the progressive number of
the newly selected page.
