/** @file test-element-access.hpp
|
|
** Unit test helper for access to UI elements without actually running an UI.
|
|
** This allows to cover functionality for resolving UI-coordinates against an UI topology
|
|
** and accessing or creating elements. Obviously, only faked UI widgets can be returned,
|
|
** but this does not matter for those features anyway.
|
|
**
|
|
** @note as of 4/2018 this is a first draft and WIP-WIP-WIP
|
|
** @todo right now this test is braindead; the idea is to extend it similar to the
|
|
** GenNodeLocationQuery eventually, so to mimic the way an actual implementation
|
|
** would drill down into the UI topology. Yet at the moment (4/2018) we are still
|
|
** far from implementing anything in this regard; we just need the interface... ///////////////////////////////TICKET #1134
