stage::model Namespace Reference

Description

The Lumiera GTK-GUI uses a thin proxy layer data model on top of the actual "high-level-model", which lives in the Steam-Layer below.

Stage operations interact with these proxy model entities, which in turn forward the calls to the actual objects in the Steam-Layer, through the Command system (which enables UNDO).

Todo:

: as of 1/2011 this connection between the GUI proxy model and the Steam-Layer model needs to be set up. Currently, the GUI model entities are just created standalone and thus dysfunctional.

: as of 11/2015 this connection between UI and Steam-Layer is actually in the works, and it is clear by now that we won't use proxy objects, but rather a generic bus-like connection and symbolic IDs to designate the model elements

: and as of 2/2017 the new structure is basically set, but we need actually to implement a new timeline display in accordance to this reworked design. After this is done, most of the model elements in this packare are obsolete.
