Fix Rect of texture to take window and stretch transform into account.
There is no need for `viewport_attach_to_screen` for embedded windows,
since their display is handled via `Viewport::_sub_window_update`.
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.
