/*
|
||
|
|
* Merged-editor safety-net Kiface() (editor-unification Part 2).
|
||
|
|
*
|
||
|
|
* In the merged kicad_editor image the pcbnew and eeschema kifaces are compiled with
|
||
|
|
* -DKiface=PcbKiface / -DKiface=SchKiface, so every module-owned call site binds
|
||
|
|
* statically to its own engine. The handful of shared common/ call sites are patched
|
||
|
|
* to resolve their owning frame's kiface exactly (eda_base_frame.cpp,
|
||
|
|
* dialog_color_picker.cpp, design_block_tree_model_adapter.cpp) and only FALL BACK to
|
||
|
|
* the plain Kiface() — which, in this image, is THIS definition. It also keeps any
|
||
|
|
* future upstream common/ caller linking.
|
||
|
|
*
|
||
|
|
* Resolution is best-effort by design: focused window → top window → KIWAY top frame,
|
||
|
|
* walking parents to an EDA_BASE_FRAME whose FRAME_T names its face. With the one-
|
||
|
|
* frame-per-page-load model there is exactly one editor frame, so the walk is exact
|
||
|
|
* in practice; FACE_PCB is the last-resort default.
