Last change on this file since 2fe4a5 was 522c45, checked in by Frederik Heber <heber@…>, 9 years ago

QtObserved... signals indexChanged does not transmit ids anymore.

  • since the change to ObservedValue_Index_t, the id is not used anymore. Only in the GUI for the objectid.
  • Property mode set to 100644
