Struct WindowRootNode 

pub struct WindowRootNode { /* private fields */ }

Node that lays its content out into the window’s size. That size is the node’s own, for the window’s scene; the layout pass reports a zero size to the node’s parent.

Implementations

impl WindowRootNode

pub fn new(descriptor: Rc<dyn WindowRootDescriptor>) -> Self

A window root described by descriptor, for a platform node that delegates its layout and registration here.

pub fn set_descriptor(&mut self, descriptor: Rc<dyn WindowRootDescriptor>)

Takes a new description of the window and re-registers the root when it is attached.

Trait Implementations

impl Debug for WindowRootNode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl DelegatableNode for WindowRootNode

fn node_state(&self) -> &NodeState

fn aggregate_child_capabilities(&self) -> NodeCapabilities

impl LayoutModifierNode for WindowRootNode

fn measure( &self, _context: &mut dyn ModifierNodeContext, measurable: &dyn Measurable, _constraints: Constraints, ) -> LayoutModifierMeasureResult

Returns the maximum intrinsic width of this modifier node.

fn min_intrinsic_height(&self, _measurable: &dyn Measurable, _width: f32) -> f32

Returns the minimum intrinsic height of this modifier node.

fn max_intrinsic_height(&self, _measurable: &dyn Measurable, _width: f32) -> f32
