/** @file navigator.cpp
|
|
** Implementation of global interface navigation mechanisms.
|
|
** Especially we implement the LocationQuery interface, which exposes the structures
|
|
** of the UI as an abstracted, tree-shaped topology. This task adds up to levelling all the
|
|
** specifics of accessing individual components and to assemble them into a virtual component tree.
|
|
** The actual details of component access are thereby delegated to the ViewLocator, which is a sibling
|
|
** service maintained by the InteractionDirector.
|
|
**
|
|
** @todo WIP 2/2017 early draft / foundations of "interaction control"
|
|
** @todo WIP 1/2018 integrating the concept of UI-Coordinate navigation and resolution. Still WIP-WIP-WIP...
