/** @file ui-location-resolver.hpp
|
||
|
|
** A solver to match incomplete coordinate specifications against the actual UI topology.
|
||
|
|
** Within the Lumiera UI, a _component view_ is typically _created or retrieved_ to live at some position
|
||
|
|
** within the tree-like topology of the interface. Such happens as a consequence of interaction or other
|
||
|
|
** events, and the logic as to where and how to place a new UI element shall not be intermingled with the
|
||
|
|
** actual event handling code. Rather, the ViewLocator, as a service related to the InteractionDirector,
|
||
|
|
** can be invoked to draw on some default configuration plus the actual UI topology present at this time.
|
||
|
|
**
|
||
|
|
** @todo WIP 2/2018 early draft ////////////////////////////////////////////////////////////TICKET #1127
