Function
ClutterIntervalregister_progress_func
Declaration [src]
void
clutter_interval_register_progress_func (
  GType value_type,
  ClutterProgressFunc func
)
Description [src]
Sets the progress function for a given value_type, like:
  clutter_interval_register_progress_func (MY_TYPE_FOO,
                                           my_foo_progress);
Whenever a ClutterInterval instance using the default
clutter_interval_compute_value() implementation is set as an
interval between two GValue of type value_type, it will call
func to establish the value depending on the given progress,
for instance:
  static gboolean
  my_int_progress (const GValue *a,
                   const GValue *b,
                   gdouble       progress,
                   GValue       *retval)
  {
    gint ia = g_value_get_int (a);
    gint ib = g_value_get_int (b);
    gint res = factor * (ib - ia) + ia;
    g_value_set_int (retval, res);
    return TRUE;
  }
  clutter_interval_register_progress_func (G_TYPE_INT, my_int_progress);
To unset a previously set progress function of a GType, pass NULL
for func.
This function is not directly available to language bindings.
