Returns the index of a child in an object node.

§Safety

The caller must ensure that self.has_child(child).

pub fn add_child(&self, child: &Node2D) -> Result<(), Error>

Adds a child node.

Adding a 3D node node as a child of a 2D node is only allowed when adding a scene to a viewport. Screens can have only one child which is a 2D node.

Adds a child node for object node to given index.

pub fn layout(&self) -> Result<(), Error>

Does a layout pass starting from this node and iterating recursively all of its children. Does a layout pass with no root transformation (identity).

Measure pass only descends up to nodes marked for requiring measure and then propagates upwards for all nodes that were changed. After measure, all nodes marked for requiring arrange and all their children are arranged.

The actual size of a node is not known before layout. You can call layout manually to determine the actual sizes of nodes. Before calling layout, the node must have allocated size set to limit node area to anything less than infinity. Normal layout process sets allocated size to current composition size.

pub fn measure( &self, available_size: Option<Vector2>, handle_stretch: bool, ) -> Result<bool, Error>

Detaches a node and its descendants.

§Safety

The caller must ensure that Self::attach_recursive was called on an object.

pub fn try_set_focus(&self) -> Result<Option<Weak<Node>>, Error>

Tries to move the focus to this node. If this node is a focus scope node, this method tries to focus the preserved focus of the focus scope, or tries to focus on the first focusable descendant node of this node.

§Arguments

resource_id - Name of the resource.
closure - Callback to execute upon completion of the task.

§Returns

Task created or an None on failure.

pub fn add_anonymous_resource(&self, resource: &Resource) -> Result<(), Error>

pub fn remove_node_component_with_owner( &self, owner: Option<&Object>, ) -> Result<(), Error>

Removes all bindings with the specified owner.

pub fn lookup_node_component( &self, name: impl AsRef<KanziStr>, ) -> Result<Option<Weak<NodeComponent>>, Error>

Methods from Deref<Target = Object>§

pub fn as_ptr(&self) -> *mut ObjectWrapper

pub fn as_wrapper(&self) -> &ObjectWrapper

pub fn as_object(&self) -> &Object

Represents any type inheriting from Object as &Object. This is useful for comparisions when PartialEq traits failed to compare objects of different types.

let child = screen.get_child(0)?;
let parent = child.get_parent()?.into_error(ErrorKind::ObjectNotFound)?;
// assert_eq!(screen, parent); // <- Fails to compile!
assert_eq!(screen.as_object(), parent.as_object());

pub fn get_native(&self) -> Result<NonNull<c_void>, Error>

Gets a pointer to the backing C++ instance.

pub fn is_stale(&self) -> bool

Checks whether the weak reference has expired.

pub fn get_property<T>( &self, property_type: &PropertyType<T>, ) -> Result<<T as VariantConstraint>::RetArg, Error>
where T: PropertyTypeConstraint,

Returns the current value of a property disregarding modifiers.

Base value is affected by the following inputs where the highest entry in the list determines the base value:

Local value set with setProperty or loaded from kzb
Value set by a style affecting the property.
Value defined by class metadata.

Modifiers are not applied, the highest-priority base value is returned.

If no inputs to the property value can be established the system returns the value default value from property type metadata.

§Arguments

property_type - The property type identifying the property to retrieve.

§Returns

The evaluated property value.

pub fn get_optional_property<T>( &self, property_type: &PropertyType<T>, ) -> Result<Option<<T as VariantConstraint>::RetArg>, Error>
where T: PropertyTypeConstraint,

Returns the current value of a property disregarding modifiers, but does not default to the value in property metadata if there are no inputs to the property value.

If there is no value sources, None is returned.

If no inputs to the property value can be established the system returns the value default value from property type metadata.
