Description [src]
class Clutter.Interval : GObject.InitiallyUnowned
implements Clutter.Scriptable {
/* No available fields */
}
An object holding an interval of two values
ClutterInterval is a simple object that can hold two values
defining an interval. ClutterInterval can hold any value that
can be enclosed inside a GValue.
Once a ClutterInterval for a specific GType has been instantiated
the ClutterInterval:value-type property cannot be changed anymore.
ClutterInterval starts with a floating reference; this means that
any object taking a reference on a ClutterInterval instance should
also take ownership of the interval by using g_object_ref_sink().
ClutterInterval can be subclassed to override the validation
and value computation.

and final.

Instance methods
clutter_interval_compute
Computes the value between the interval boundaries given the
progress factor.
since: 13
clutter_interval_compute_value
Computes the value between the interval boundaries given the
progress factor and copies it into value.
since: 13
clutter_interval_get_final_value
Retrieves the final value of interval and copies
it into value.
since: 13
clutter_interval_get_initial_value
Retrieves the initial value of interval and copies
it into value.
since: 13
clutter_interval_get_interval
Variable arguments wrapper for clutter_interval_get_initial_value()
and clutter_interval_get_final_value() that avoids using the
GValue arguments:
since: 13
clutter_interval_set_final
Variadic arguments version of clutter_interval_set_final_value().
since: 13
clutter_interval_set_final_value
Sets the final value of interval to value. The value is
copied inside the ClutterInterval.
since: 13
clutter_interval_set_initial
Variadic arguments version of clutter_interval_set_initial_value().
since: 13
clutter_interval_set_initial_value
Sets the initial value of interval to value. The value is copied
inside the ClutterInterval.
since: 13
clutter_interval_set_interval
Variable arguments wrapper for clutter_interval_set_initial_value()
and clutter_interval_set_final_value() that avoids using the
GValue arguments:
since: 13
clutter_interval_validate
Validates the initial and final values of interval against
a GParamSpec.

Methods inherited from ClutterScriptable (4)
clutter_scriptable_get_id
Retrieves the id of scriptable set using clutter_scriptable_set_id().
since: 13
clutter_scriptable_parse_custom_node
Parses the passed JSON node. The implementation must set the type
of the passed GValue pointer using g_value_init().
since: 13
clutter_scriptable_set_custom_property
Overrides the common properties setting. The underlying virtual function should be used when implementing custom properties.
since: 13
clutter_scriptable_set_id
Sets id_ as the unique Clutter script it for this instance of
ClutterScriptableIface.

Signals
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
