METHODS

   object = Gtk2::Adjustment->new ($value, $lower, $upper, $step_increment, $page_increment,
       $page_size)
       •   $value (double)

       •   $lower (double)

       •   $upper (double)

       •   $step_increment (double)

       •   $page_increment (double)

       •   $page_size (double)

   $adjustment->changed
   $adjustment->clamp_page ($lower, $upper)
       •   $lower (double)

       •   $upper (double)

   $adjustment->configure ($value, $lower, $upper, $step_increment, $page_increment, $page_size)
       •   $value (double)

       •   $lower (double)

       •   $upper (double)

       •   $step_increment (double)

       •   $page_increment (double)

       •   $page_size (double)

       Since: gtk+ 2.14

   $adjustment->set_lower ($newval)
   $adjustment->set_page_increment ($newval)
   $adjustment->set_page_size ($newval)
   $adjustment->set_step_increment ($newval)
   $adjustment->set_upper ($newval)
       •   $newval (double)

       These functions differ from the plain "->lower" etc setters in that they emit "notify" and
       "changed" signals if $newval is different from the current value.

       The corresponding "get_lower" etc are not wrapped because they're the same as the "lower"
       etc field accessors above.

       Since: gtk+ 2.14

   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_increment
   double = $adjustment->page_increment ($newval)
   double = $adjustment->page_size
   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.

   $adjustment->value_changed
   double = $adjustment->get_value
   $adjustment->set_value ($value)
       •   $value (double)

PROPERTIES

       'lower' (double : default 0 : readable / writable / private)
           The minimum value of the adjustment

       'page-increment' (double : default 0 : readable / writable / private)
           The page increment of the adjustment

       'page-size' (double : default 0 : readable / writable / private)
           The page size of the adjustment

       'step-increment' (double : default 0 : readable / writable / private)
           The step increment of the adjustment

       'upper' (double : default 0 : readable / writable / private)
           The maximum value of the adjustment

       'value' (double : default 0 : readable / writable / private)
           The value of the adjustment
