My bad,
Calling the parent "allocate" method fixed the problem. My allocate
function now looks like this:
static void
txvc_site_view_allocate(ClutterActor *self,
const ClutterActorBox *box,
ClutterAllocationFlags flags)
{
TxvcSiteViewPrivate *priv = GET_PRIVATE(self);
ClutterActorBox *child;
ClutterLayoutManager *layout;
g_debug("Allocating actor");
CLUTTER_ACTOR_CLASS(txvc_site_view_parent_class)->allocate(self,
box, flags);
/* allocate the whole area to our bin, and let it take
* care of managing all children
*/
child =
clutter_actor_box_new(0.0f, 0.0f,
box->x2 - box->x1,
box->y2 - box->y1);
clutter_actor_allocate(priv->bin,
child, flags);
clutter_actor_box_free(child);
}
Thanks,
Uday
