Introduced atom_observables and GLWorldView observes World, GLMoleculeObject_atom observes its atom.

Observer changes:

  • new Channels pattern required from CodePatterns 1.1.5 and that Observable signing on and off is now with const instance possible.
  • class atom is now observable, encapsulated in class AtomObservable:
    • enums have notification types
    • we use NotificationChannels of Observable to emit these distinct types.
  • atominfo, particleinfo, bondedparticleinfo all have OBSERVE and NOTIFY(..) in their setter functions (thx encapsulation).
  • class GLMoleculeObject_atom signs on to atom to changes to position, element, and index.
  • World equally has notifications for atom (new,remove) and molecules (new, remove).
  • GLWorldView now observes World for these changes.

Other changes:

  • removed additional hierarchy level for GLWidget of molecules (i.e. GLMoleculeScene removed and incorporated into GLWorldScene).
  • Property mode set to 100644
