$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

$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.

$value (double)

'lower' (double : default 0 : readable / writable / private / static-nick / static-blurb)
The minimum value of the adjustment
'page-increment' (double : default 0 : readable / writable / private / static-nick / static-blurb)
The page increment of the adjustment
'page-size' (double : default 0 : readable / writable / private / static-nick / static-blurb)
The page size of the adjustment
'step-increment' (double : default 0 : readable / writable / private / static-nick / static-blurb)
The step increment of the adjustment
'upper' (double : default 0 : readable / writable / private / static-nick / static-blurb)
The maximum value of the adjustment
'value' (double : default 0 : readable / writable / private / static-nick / static-blurb)
The value of the adjustment

changed (Gtk2::Adjustment)
value-changed (Gtk2::Adjustment)
