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.
