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)

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 : readable / writable / private)

'step-increment' (double : readable / writable / private)

The step increment of the adjustment

'upper' (double : readable / writable / private)
