METHODS

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

35   $adjustment->configure ($value, $lower, $upper, $step_increment,
36       $page_increment, $page_size)

51   $adjustment->set_lower ($newval)
52   $adjustment->set_page_increment ($newval)
53   $adjustment->set_page_size ($newval)

55   $adjustment->set_upper ($newval)
56       ·   $newval (double)
57
58       These functions differ from the plain "->lower" etc setters in that
59       they emit "notify" and "changed" signals if $newval is different from
60       the current value.
61
62       The corresponding "get_lower" etc are not wrapped because they're the
63       same as the "lower" etc field accessors above.

65       Since: gtk+ 2.14
66
67   double = $adjustment->value
68   double = $adjustment->value ($newval)
69   double = $adjustment->lower
70   double = $adjustment->lower ($newval)
71   double = $adjustment->upper
72   double = $adjustment->upper ($newval)
73   double = $adjustment->step_increment
74   double = $adjustment->step_increment ($newval)
75   double = $adjustment->page_increment
76   double = $adjustment->page_increment ($newval)
77   double = $adjustment->page_size
78   double = $adjustment->page_size ($newval)
79       ·   $newval (double)
80
81       Get or set the six fields of a Gtk2::Adjustment.
82
83       The setter functions store $newval and return the old value.  Note that
84       they don't emit any signals; it's up to you to emit "notify" (because
85       the fields are also properties) and "changed" or "value-changed", when
86       you're ready.
