g_signal_connect_object (
  GObjectTypeInstance* instance,
  const gchar* detailed_signal,
  GCallback c_handler,
  GObject* gobject,
  GConnectFlags connect_flags


This is similar to g_signal_connect_data(), but uses a closure which ensures that the gobject stays alive during the call to c_handler by temporarily adding a reference count to gobject.

When the gobject is destroyed the signal handler will be automatically disconnected. Note that this is not currently threadsafe (ie: emitting a signal while gobject is being destroyed in another thread is not safe).
