Calculate based on the `ScrollContainer`'s space to eliminate possible
rotation. The global rect already has applied the rotation, so it
should not be used.
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".
DisplayServer::screen_is_touchscreen will likely never utilize its
parameter p_screen.
This PR replaces this function by DisplayServer::is_touchscreen_available()
with the same functionality.
This solves the problem, that a SubViewport was used for determining
the screen, which resulted in error messages.
CanvasItemEditor:
- p_result == ADD_MOVE is always true in this switch-clause
- both parts of the if-else-clause do the same thing and simplified an affine_inverse call
ControlEditorToolbar:
- private function ControlEditorToolbar::_anchor_to_position is used nowhere. Looks like
copy and paste from CanvasItemEditor::_anchor_to_position
ScrollContainer:
- screen_is_touchscreen is always true, because otherwise the function already returned
TextLine:
- both parts of the if-else-clause do the same thing and simplified return statement
The visibility of the `ScrollBar` was used as a condition for judging whether it should scroll.
**Visible** and **scrollable** are currently not the same in some cases (`SCROLL_MODE_SHOW_NEVER`).
This makes `SCROLL_MODE_SHOW_NEVER` not working properly.
This patch will make `SCROLL_MODE_SHOW_NEVER` available, so that the external `SrollBar` can
share the internal `ScrollBar`'s data, we can achieve the purpose of replacing the internal
`ScrollBar` with a custom external one.
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()`).
Previously, the data used by `update_scrollbars()` and `_update_dimensions()` in their calculations depended on each other, which caused some problems.
Now, the calculation of `child_max_size` is put into `get_minimum_size()`, as the containers call `update_minimum_size()` before calling `queue_sort()`.
Make the semantics of variable/function names more clear.
