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)
