* This notification makes node children management very inefficient.
* Replaced by a NOTIFICATION_CHILDREN_CHANGED (and children_changed signal).
* Changed Canvas code (and similar) to use the above signal, to perform more efficiently.
This PR breaks compatibility (although this notification was very rarely used, even within the engine), but provides an alternate way to do the same.
It is required for the changes in #75627 to be entirely effective.
This patch adds a viewport-configuration-option for sorting
physics-picking events by the Z-Index and the scene tree position
of the collision objects.
CanvasItem::get_screen_transform returns a transform from the CanvasItem
to the coordinate system, where a Popup - created as a child of the
CanvasItem - should be opened.
get_screen_transform makes some simplifications, that work well, when used
in the editor, but not in general cases.
Since Popups like Tooltips are now used more commonly in projects,
it becomes necessary to correct these simplifications.
This solution introduces Viewport::get_popup_base_transform, which makes
the necessary calculations.
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".
In certain conditions events did not get propagated to Control childs of
Node2D nodes when setting a parent of the Node2D to toplevel.
This patch makes sure that such Control nodes become root control in the
viewport.
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`.
