AtkValue should be implemented for components which either display a value from a bounded range, or which allow the user to specify a value from a bounded range, or both. For instance, most sliders and range controls, as well as dials, should have AtkObject representations which implement AtkValue on the component's behalf. AtKValues may be read-only, in which case attempts to alter the value return FALSE to indicate failure.
void atk_value_get_current_value (AtkValue *obj, GValue *value); |
Gets the value of this object.
a GObject instance that implements AtkValueIface
a GValue representing the current accessible value
void atk_value_get_maximum_value (AtkValue *obj, GValue *value); |
Gets the maximum value of this object.
a GObject instance that implements AtkValueIface
a GValue representing the maximum accessible value
void atk_value_get_minimum_value (AtkValue *obj, GValue *value); |
Gets the minimum value of this object.
a GObject instance that implements AtkValueIface
a GValue representing the minimum accessible value
gboolean atk_value_set_current_value (AtkValue *obj, const GValue *value); |
Sets the value of this object.
a GObject instance that implements AtkValueIface
a GValue which is the desired new accessible value.
TRUE if new value is successfully set, FALSE otherwise.
