Functions
clutter_behaviour_opacity_new ()
ClutterBehaviour * clutter_behaviour_opacity_new (ClutterAlpha *alpha,guint8 opacity_start,guint8 opacity_end);
clutter_behaviour_opacity_new has been deprecated since version 1.6 and should not be used in newly-written code.
Creates a new ClutterBehaviourOpacity object, driven by alpha
which controls the opacity property of every actor, making it
change in the interval between opacity_start
and opacity_end
.
If alpha
is not NULL, the ClutterBehaviour will take ownership
of the ClutterAlpha instance. In the case when alpha
is NULL,
it can be set later with clutter_behaviour_set_alpha().
Parameters
alpha |
a ClutterAlpha instance, or |
[allow-none] |
opacity_start |
minimum level of opacity |
|
opacity_end |
maximum level of opacity |
Since: 0.2
clutter_behaviour_opacity_set_bounds ()
void clutter_behaviour_opacity_set_bounds (ClutterBehaviourOpacity *behaviour,guint8 opacity_start,guint8 opacity_end);
clutter_behaviour_opacity_set_bounds has been deprecated since version 1.6 and should not be used in newly-written code.
Sets the initial and final levels of the opacity applied by behaviour
on each actor it controls.
Since: 0.6
clutter_behaviour_opacity_get_bounds ()
void clutter_behaviour_opacity_get_bounds (ClutterBehaviourOpacity *behaviour,guint8 *opacity_start,guint8 *opacity_end);
clutter_behaviour_opacity_get_bounds has been deprecated since version 1.6 and should not be used in newly-written code.
Gets the initial and final levels of the opacity applied by behaviour
on each actor it controls.
