$upper (double)

double = $adjustment->value

double = $adjustment->value ($newval)

double = $adjustment->lower

double = $adjustment->lower ($newval)

double = $adjustment->upper

double = $adjustment->upper ($newval)

double = $adjustment->step_increment

double = $adjustment->step_increment ($newval)

double = $adjustment->page_size ($newval)

*

$newval (double)

Get or set the six fields of a Gtk2::Adjustment.
The setter functions store $newval and return the old value. Note that they don't emit any signals; it's up to you to emit ``notify'' (because the fields are also properties) and ``changed'' or ``value-changed'', when you're ready.
