示例1:
/* For the sigc::connection changes (i.e. when the object being refered to changes) */
static void
sp_tref_href_changed(SPObject */*old_ref*/, SPObject */*ref*/, SPTRef *tref)
{
if (tref)
{
// Save a pointer to the original object being referred to
SPObject *refRoot = tref->getObjectReferredTo();
tref->_delete_connection.disconnect();
if (tref->stringChild) {
tref->detach(tref->stringChild);
tref->stringChild = NULL;
}
// Ensure that we are referring to a legitimate object
if (tref->href && refRoot && sp_tref_reference_allowed(tref, refRoot)) {
// Update the text being referred to (will create a new string child)
sp_tref_update_text(tref);
// Restore the delete connection now that we're done messing with stuff
tref->_delete_connection = refRoot->connectDelete(sigc::bind(sigc::ptr_fun(&sp_tref_delete_self), tref));
}
}
}示例2:
void
sp_conn_end_href_changed(SPObject */*old_ref*/, SPObject */*ref*/,
SPConnEnd *connEndPtr, SPPath *const path, unsigned const handle_ix)
{

if (refobj) {

= refobj->connectDelete(sigc::bind(sigc::ptr_fun(&sp_conn_end_deleted),
path, handle_ix));
// This allows the connector tool to dive into a group's children
// And connect to their children's centers.
SPObject *parent = refobj->parent;
if (SP_IS_GROUP(parent) && ! SP_IS_LAYER(parent)) {
connEnd._group_connection
= SP_ITEM(parent)->connectTransformed(sigc::bind(sigc::ptr_fun(&sp_conn_end_shape_move),
