ClutterSnapConstraint is a constraint the snaps the edges of two actors together, expanding the actor's allocation if necessary.
An offset can be applied to the constraint, to provide spacing.
ClutterSnapConstraint is available since Clutter 1.6
ClutterConstraint * clutter_snap_constraint_new (ClutterActor *source,ClutterSnapEdge from_edge,ClutterSnapEdge to_edge,gfloat offset);
Creates a new ClutterSnapConstraint that will snap a ClutterActor
to the edge
of source
, with the given offset
.

void clutter_snap_constraint_set_source (ClutterSnapConstraint *constraint,ClutterActor *source);
Sets the source ClutterActor for the constraint
Since: 1.6
ClutterActor *
clutter_snap_constraint_get_source (ClutterSnapConstraint *constraint);
Retrieves the ClutterActor set using clutter_snap_constraint_set_source()
Since: 1.6
void clutter_snap_constraint_set_edges (ClutterSnapConstraint *constraint,ClutterSnapEdge from_edge,ClutterSnapEdge to_edge);
Sets the edges to be used by the constraint
The from_edge
is the edge on the ClutterActor to which constraint
has been added. The to_edge
is the edge of the ClutterActor inside
the “source” property.
Since: 1.6
void clutter_snap_constraint_get_edges (ClutterSnapConstraint *constraint,ClutterSnapEdge *from_edge,ClutterSnapEdge *to_edge);
Retrieves the edges used by the constraint
