Observable Properties

Scalqa properties define 4 basic types:

  • Pro - read-only property
  • Pro.M - mutable property
  • Pro.O - observable property
  • Pro.OM - observable and mutable property

and they are hierarchical:

      Pro.O
    /       \
Pro           Pro.OM
    \       /
      Pro.M

Observable properties are the base for development of GUI event based controls
