- Instead of checking for Key::UP, Key::DOWN, Key::PAGEUP, Key::PAGEDOWN etc., we rather check for the action like 'ui_up' or 'ui_down'.
- Also use AcceptDialog's 'register_text_enter' functionality to consistently close a dialog when ENTER is pressed while the LineEdit has focus (instead of redirecting ENTER keys to e.g. the underlying Tree).
- Unify the LineEdit filter behavior for the SceneTreeDialog and corresponding usages
- Improve OK Button disablement (something should be selected)
99% of the time we shouldn't rely on the signal, we
should use the notification instead. I left some comments
in places where I couldn't quickly improve the code.
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
* `_gui_input`, `_input`, `_unhandled_input` and `_unhandled_key_input` are now regular C++ virutal functions.
* Everything else converted to GDVIRTUAL
* BIND_VMETHOD is gone, always use the new syntax from now on.
Creating `_gui_input` method and using the binder to register events will no longer work, simply override the virtual function now.
