A single mouse click can cause multiple actions, which contradicts
the paradigm that a single Input Event should cause only a single
action.
The solution consists of two parts:
1. Physics Picking as the last step during viewport input event
handling, currently doesn't set the event as handled. This PR sets
the event as handled in the case of physics picking.
2. After an InputEvent is processed by a SubVieportContainer, it is
sent to its parent, even if it set as handled within the SubViewport.
This PR adds an additional test to check if the event is handled
before propagating the event to the parent Control.
When node tree `A` is not in the tree, `remove_child(B)` will not
automatically clean up the owners of `B` and `B`'s child nodes.
This is convenient for implementing operations like `replace_by()`,
but may have hidden dangers when manipulating the rest of the tree
`A`.
This commit makes it safe to manipulate the rest of `A` after freeing
`B`.
The associated `ViewportTexture`s will update the `viewport_path`
in time when the `Viewport`'s nodepath is changed (caused by renaming
the node names or moving in the SceneTree dock).
If the target `Viewport` is changed by resetting the `viewport_path`,
the `ViewportTexture`s will be re-setup and emit `changed` signal in
time.
* Node processing works on the concept of process groups.
* A node group can be inherited, run on main thread, or a sub-thread.
* Groups can be ordered.
* Process priority is now present for physics.
This is the first steps towards implementing https://github.com/godotengine/godot-proposals/issues/6424.
No threading or thread guards exist yet in most of the scene code other than Node. That will have to be added later.
* Adding and removing child nodes is now constant time, speed up should be huge.
* Searching for node paths as in ("path/to/node") should be far faster too.
This changes the children management and makes it a hashmap, optimizing most StringName based operations.
Most operations should be severe speed up without breaking compatibility.
This should fix many issues regarding to node access performance, and may also speed up editor start/end, but benchmarks are needed. So if you want to test, please make some benchmarks!
Further performance improvements will be done in the future by removing NOTIFICATION_MOVED_IN_PARENT and replacing by something less laborious.
With change 104392e the code to update node indices on removal was erronously removed.
The out of date indices would cause crashes while selecting nodes in a graph editor (e.g. animation tree) and selected nodes are oftern pushed to beginning or end of the child list for the parent.
* 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.
* Make placeholder in editor layout dialog translatable.
* Make messages in scene import settings dialog translatable.
* Mark theme override property categories for translation.
Fixes#75084.
The clamp_to_embedder setting was added in 8be16e0704,
but was not set on any of the in-editor dialogs.
This patch sets `clamp_to_embedder` on editor dialogs so they cannot be dragged out of the frame.
This also modifies `clamp_to_embedder` so a window is clamped to the bounds of an embedder when
it pops up and when the parent is resized.
This solves the problem, that mouse events get sent to SubViewports
even if they are outside of the visible area of the SubViewport.
This changes makes SubViewportContainer::unhandled_input redundand.
Shortcut Events now need to be distributed via push_input, in order for
them to be able to reach SubViewports.
In the editor, it was possible to set the size of a `SubViewport` even
in cases where a parent `SubViewportContainer` had stretch enabled.
This PR disables editing a `SubViewport.size` while the parent disallows
it and it makes necessary adjustments during `NOTIFICATION_ENTER_TREE`.
After a scene reload a mouse cursor updates is performed via a
InputEventMouseMotion, that is exposed to the user.
The state of Input is however not adjusted to this InputEventMouseMotion
which can lead to inconsistencies.
This PR makes sure, that it is not exposed to the user.
It utilizes the method of Viewport::_process_picking for marking
events that are not sent to the user, so that this function doesn't
need to be changed.
With the 4.x-introduction of Windows the previous method for
color picking was no longer working.
This PR uses the following approach to reintroduce color-picking.
When the Color-Picking-Button is pressed, a quasi-screenshot of the
Window-content is created and displayed in a new Popup-Window.
This new Window allows selecting colors by Mouse-Click.
A Preview of the targeted Color is also displayed.
1. `number_width` isn't used later
2. `return_type` is used only once
3. AudioServer::get_singleton()->get_channel_count() always returns a channel_count of 1 or larger
4. negative `aa->backward` conditional
5. `current_canvas` == `find_world_2d()->get_canvas()`
6. identical if `render_shadows`
Some internally created emulated/instantiated events didn't have a
device id. This PR sets for these cases a device id.
Also rename `DEVICE_ID_TOUCH_MOUSE` to the more generic
`DEVICE_ID_EMULATION`.
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.
`Viewport.to_screen_rect` is used only in a single location to compare it
to `Rect2i()`.
When called from `SubViewport`, `to_screen_rect` is always equal to `Rect2i()`.
When called from `Window`, `to_screen_rect` is always different from `Rect2i()`.
So the comparison `to_screen_rect != Rect2i()` can be replaced by
`Object::cast_to<Window>(this)`.
This allows the removal of `Viewport.to_screen_rect` and the simplification of
`Viewport::_set_size`.
You still need to select another node to see the tooltip updated first,
but you no longer need to save and reopen the scene to view the updated
tooltip.
Use a TLSOptions configuration object which is created via static
functions.
- "TLSOptions.client": uses the standard CA and common name verification.
- "TLSOptions.client_unsafe": uses optional CA verification (i.e. if specified)
- "TLSOptions.server": is the standard server configuration (chain + key)
This will allow us to expand the TLS configuration options to include
e.g. mutual authentication without bloating the classes that uses
StreamPeerTLS and PacketPeerDTLS as underlying peers.
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.
