virtualx-engine/editor/scene_tree_editor.cpp
Juan Linietsky e6a4debede Change set_drag_forwarding() to use callables. 
* This solution is much cleaner than the one in 3.x thanks to the use of callables.
* Works without issues in any language (no need to worry about camel or snake case).
* Editor code uses a compatibility function (too much work to redo).

Fixes #59899
