Make Drag and Drop an application-wide operation.
This allows do drop on Controls in other Viewports/Windows.
In order to achieve this, `Viewport::_update_mouse_over` is adjusted to
remember the Control, that the mouse is over (possibly within nested
viewports). This Control is used as a basis for the Drop-operation, which
replaces the previous algorithm, which was only aware of the topmost
Viewport.
Also now all nodes in the SceneTree are notified about the Drag and Drop
operation, with the exception of SubViewports that are not children of
SubViewportContainers.
Changes to reduce the latency between changing node selection in the editor and seeing the new node reflected in the Inspector tab
- Use Vector instead of List for ThemeOwner::get_theme_type_dependencies and related functions
- Use Vector instead of List for ThemeContext::themes, set_themes(), and get_themes()
- Add ClassDB:get_inheritance_chain_nocheck to get all parent/ancestor classes at once, to avoid repeated ClassDB locking overhead
- Update BIND_THEME_ITEM macros and ThemeDB::update_class_instance_items to use provided StringNames for call to ThemeItemSetter, instead of creating a new StringName in each call
These changes reduce the time taken by EditorInspector::update_tree by around 30-35%
On Windows this allows to avoid having to change the owner of the window
after it has been created, which in rare circumstances may cause the
window to bug out.
In some cases it can happen, that the order of input events and
window events is not followed, when input buffering or input accumulation
is active.
The display server order `InputEvent` => window-event gets changed to
window-event => `InputEvent` which becomes problematic in certain
situations.
This PR makes sure, that the order is adhered to by flushing input events
before a window event is sent.
Previously this problem was mitigated by discarding these delayed events.
But this solution was problematic in the setting of android input events.
This intends to be the correct way to handle non-child windows becoming covered by the current window when becoming focused.
Enabling this property on select windows, they will become transient to the currently focused one when becoming visible.
This deprecates the "unparent_when_invisible" function introduced by #76025.
`AcceptDialog`, `Popup` and `PopupMenu` no longer subscribe to
"window_input" signal, because that is only sent if it is not an
internal signal.
Instead they receive events in `_input_from_window`. They ensure that
the event is also propagated to their super-function, just like
previously the signals would be treated.
This adds binds for GraphEdit/GraphElement/GraphNode, which were
skipped before due to a rework. This also adds binds for Window,
which was skipped before due to a complicated code organization.
Also adds theme cache entries/direct cache access to a few places
that previously missed it. Some theme properties are now exposed
to other classes via friendships or public getters for convenience.
This removes all string-based theme access from scene/ classes.
This commit adds the default theme context, which replaces
the need to manually check the project and the default theme
all the time; simplifies related code.
It also adds framework for custom theme contexts, to be used
by the editor. Custom contexts can be attached to any node,
and not necessarily a GUI/Window node. Contexts do no break
theme inheritance and only define which global themes a node
uses as a fallback.
Contexts propagate NOTIFICATION_THEME_CHANGED when one of their
global themes changes. This ensures that global themes act just
like themes assigned to individual nodes and can be previewed
live in the editor.
Integer scaling is achieved (after aspect expansion) by "lying" to the
stretching code about the window's size, telling it that it's always an
integer multiple of the viewport so that it only gets stretched to an
integer factor.
This approach works with all stretch and aspect modes and doesn't
require handling for each, only requiring to "loosen up" some
self-excluding conditions (in other words, replacing some `else if`s
with just `if`s) regarding viewport offset and margin calculation (black
bars).
Includes a tiny usability change that adds a range hint for the content
scale factor between 0.5 to 8.0.

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.
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.
Currently the window receives a focus-out notification, directly after
it popup, because currently the signal is sent deferred.
The original intention was that the previously focused window must
receive a focus-out notification.
This change makes the notification more precise by only sending the
focus-out to the previously focused window.
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.
