Previously for InputEvents there was no distinction between
Window-area and Viewport-area.
This was problematic in cases where stretching was used and the Window
contained black bars at the sides of the Viewport.
This PR separates the area of Window and Viewport regarding InputEvents.
Saving a subscene causes the main scene to be re-instantiated. And the resource
instance in the main scene will be reused when the main scene is re-instantiated.
So for resources with `resource_local_to_scene` enabled, resetting state may be
necessary (at least for `ViewportTexture`).
This is needed to allow 2D to fully make use of 3D effects (e.g. glow), and can be used to substantially improve quality of 2D rendering at the cost of performance
Additionally, the 2D rendering pipeline is done in linear space (we skip linear_to_srgb conversion in 3D tonemapping) so the entire Viewport can be kept linear.
This is necessary for proper HDR screen support in the future.
The previous implementation for signals mouse_entered and mouse_exited
had shortcomings that relate to focused windows and pressed mouse buttons.
For example a Control can be hovered by mouse, even if it is occluded by
an embedded window.
This patch changes the behavior, so that Control and Viewport send
their mouse-enter/exit-notifications based solely on mouse position,
visible area, and input restrictions and not on which window has
focus or which mouse buttons are pressed. This implicitly also
changes when the mouse_entered and mouse_exited signals are sent.
This functionality can not be implemented as a part of
Viewport::_gui_input_event, because of its interplay with Windows and
because Viewport::_gui_input_event is based on input and not on
visibility.
This PR removes the error-message, which is currently expected to happen.
The task of correctly fixing the underlying problem of window popup
closing is more complex, so this PR solves the immediate
error-notification-problem.
When the parent `SubViewportContainer` ignores mouse with
`MOUSE_FILTER_IGNORE` and also when the mouse is over a `Control`-node,
then the `SubViewport` shouldn't create mouse-move-events for passive
hovering.
Propagate `InputEvents` without position either
- during the Input-stage, when it has focus or
- during the Unhandled-Input-stage, otherwise
This makes sure that Gui-Input happens in the correct order.
Move "Unhandled key Input" handling before "Unhandled Input" handling,
so that Unicode input with Alt / Ctrl modifiers are sent to the nodes
in the correct order.
Change the default focus mode of `SubViewportContainer` from
`FOCUS_NONE` to `FOCUS_CLICK`, to automatically remove focus from
other `Control`-nodes, when clicking inside a `SubViewport`.
Currently the input-handled-state for different events can interfere with
each other.
This PR makes sure, that the input_handled_state is reset before
processing and InputEvent during physics-picking.
At the moment it is impossible to distinguish between focused and
unfocused embedded Windows.
Add a new `theme_item` that is used for coloring the border of
unfocused Windows.
`vp_pending` is a flag indicating to wait for `ViewportTexture::_setup_local_to_scene`
to be called. Once this method is called, no matter whether the setup will fail or not,
it needs to be reset to `false`.
CPPcheck found most of them.
no need to assign the variable twice:
- AnimationTrackEditTypeAudio
- SSEffects
variable is assigned in all if-else clauses:
- EditorHelp
- AndroidInputHandler
- MenuBar
- ShaderCompiler
same if clause:
- ItemList
clearing an empty bitfield has no effect:
- Viewport
When changing `viewport_path`, the `proxy`'s target is changed to a new placeholder.
Add a flag `vp_changed` to prevent calling `setup_local_to_scene` (mainly called by toggling `resource_local_to_scene`) when the target viewport has not changed.
Currently mouse hovering doesn't update the state, when collision objects
or the camera move.
This PR fixes this problem by taking the mouse position from the viewport
and not from a nonexistent previous event.
Since previous events could potentially be a long time ago, their
modifier-key state might be outdated. This PR fetches the current
status of modifier-keys from `Input`.
These changes allow the removal of some class-variables and making
additional simplifications.
When a Viewport is not directly attached to the screen, the
function `Viewport::get_mouse_position` can't rely on
`get_screen_transform`, because that function is ambiguous in
these situations.
In these cases it is necessary to use the mouse position from
the most recent mouse IputEvent.
AnimationNodeBlendSpace2DEditor:
- `!tree` is always false, because it is checked a few lines above
CurveEdit:
- grabbing != GRAB_NONE is redundant
GradientTexture2DEdit:
- grabbed != HANDLE_FROM is redundant
- grabbed != HANDLE_TO is redundant
Viewport:
- index is not used afterwards
- In these cases `gui.mouse_focus` is always valid. Move check to a DEV_ASSERT
- simplify `stopped` calculation
The functionality of `push_unhandled_input` has changed so that it no
longer propagates input events to SubViewports.
This makes it less predictable and it should be deprecated in favor of
`push_input` which provides the same functionality and more.
Also this deprecation simplifies the Viewport-API by reducing the methods
for pushing input events, so that users don't need to worry about when
to use which function in order to insert input events.
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.
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.
* 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.
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`.
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`.
