With this solution, somewhere deep down within the implementation the knowledge about the actual result type would be encoded into the embedded VTable within a lib::variant. At interface level, ther will be a double dispatch based on that result type and the desired result type, leading either to a successful access or an error response.

** A service to discover and access raw UI elements in a cross cutting way.
|
|
** This is the actual low-level implementation of the model::ElementAccess interface
|
|
** Tightly coupled to the internals of Lumiera's GTK UI, this implementation embodies
|
|
** all the inside knowledge necessary to navigate over the various levels (Windows,
|
|
** panels, views, specific components) to get at those elements abstracted as
|
|
** UI-Coordinates.
|
|
**
|
|
** @note as of 4/2018 this is a first draft and will remain unimplemented for the time being
|
|
** @todo WIP-WIP-WIP need to learn more about the concrete UI implementation ///////////////////////TICKET #1134
