This change defines additional theme contexts for editor
branches to prevent theme leaking between the default
theme, the project theme, and the editor theme.
- Both editor window and EditorNode define an editor-specific
context with the editor theme and the default theme.
- The 2D viewport defines a project-specific context with
the project theme and the default theme.
- Theme editor preview tabs define the default-only context
with the default theme.
Additionally, the default theme context now only includes
the project theme for running projects (both export and debug).
This prevents the project theme from leaking into the editor.
This commit also does a little clean up on the theming aspects
of the EditorNode.
Also start organizing editor-specific GUI components
into a dedicated folder, `editor/gui`.
Also move `editor_file_server` next to the rest of debugger classes.
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".
Affects a lot of classes. Very thoroughly checked signal connections and deferred calls to this method, add_do_method/add_undo_method calls, and so on.
Also renames the internal `_update_callback()` to `_redraw_callback()` for consistency.
Just a few comments have also been changed to say "redraw".
In CPUParticles2D, there was a private variable with the same name. It has been renamed to `do_redraw`.
This reverts commit 4b817a565c.
Fixes#64988.
Fixes#64997.
This caused several regressions (#64988, #64997,
https://github.com/godotengine/godot/issues/64997#issuecomment-1229970605)
which point at a flaw in the current logic:
- `Control::NOTIFICATION_ENTER_TREE` triggers a *deferred* notification with
`NOTIFCATION_THEME_CHANGED` as introduced in #62845.
- Some classes use their `THEME_CHANGED` to cache theme items in
member variables (e.g. `style_normal`, etc.), and use those member
variables in `ENTER_TREE`, `READY`, `DRAW`, etc. Since the `THEME_CHANGE`
notification is now deferred, they end up accessing invalid state and this
can lead to not applying theme properly (e.g. for EditorHelp) or crashing
(e.g. for EditorLog or CodeEdit).
So we need to go back to the drawing board and see if `THEME_CHANGED` can be
called earlier so that the previous logic still works?
Or can we refactor all engine code to make sure that:
- `ENTER_TREE` and similar do not depend on theme properties cached in member
variables.
- Or `THEME_CHANGE` does trigger a general UI update to make sure that any
bad theme handling in `ENTER_TREE` and co. gets fixed when `THEME_CHANGE`
does arrive for the first time. But that means having a temporary invalid
(and possibly still crashing) state, and doing some computations twice
which might be heavy (e.g. `EditorHelp::_update_doc()`).
This reverts commit a988fad9a0.
As discussed in #57725 and clarified in #57788, `SNAME` is not meant to be used
everywhere but only in critical code paths. For theme methods specifically, it
was by design that only getters use `SNAME` and not setters.
* Added a new macro SNAME() that constructs and caches a local stringname.
* Subsequent usages use the cached version.
* Since these use a global static variable, a second refcounter of static usages need to be kept for cleanup time.
* Replaced all theme usages by this new macro.
* Replace all signal emission usages by this new macro.
* Replace all call_deferred usages by this new macro.
This is part of ongoing work to optimize GUI and the editor.
