[GTK+] Dynamically control the GtkRange widgets

[Geiger Ho <s997659 ee cuhk edu hk>]

Hi all,

  I'm using GTK+-1.2.

  Which "scrolling" widgets and how to use them for dynamically changing
their upper bound values and the "slider" length,  and being able to
display their current values?

  Thanks in advance.

Regards,
Geiger
