Struct HighlightedRect 

pub struct HighlightedRect {
    pub rect: LogicalRect,
    pub angle: f32,
    pub renders_as_rectangle: bool,
    pub local_rect: LogicalRect,
    pub parent_transform: ItemTransform,
    pub transform_rotation: f32,
    pub corner_radii: CornerRadii,
}

Available on crate feature internal-highlight only.

The rectangle of an element, which may be rotated around its center.

Fields

rect: LogicalRect

The element’s geometry.

angle: f32

In degrees, around the center of the element.

renders_as_rectangle: bool

Whether rect and angle describe the element’s rendered shape.

The two of them describe a rotated rectangle. An element renders as one while its own and its ancestors’ transforms keep its two axes at a right angle. A non-uniform scale combined with a rotation shears it into a parallelogram instead, which only local_rect still describes.

local_rect: LogicalRect

The element’s rectangle in its parent’s coordinate system.

This is what the source x, y, width and height describe. Unlike rect, no transform of the element or of any of its ancestors applies to it.

parent_transform: ItemTransform

Maps this instance’s parent coordinate system to root coordinates.

Invert it to turn a position picked in root coordinates into one that can be written to the source. It is composed from the instance’s own ancestors, so it stays correct even if the element is positioned outside of (or with a negative offset relative to) its parent.

transform_rotation: f32

Evaluated parent-relative rotation in degrees, including complete turns.

corner_radii: CornerRadii

Evaluated corner radii in logical pixels.

Implementations

impl HighlightedRect

pub fn parent_origin(&self) -> LogicalPoint

Absolute origin of this instance’s parent coordinate system, in root coordinates.

pub fn parent_rotation(&self) -> f32

Absolute rotation (in degrees) of this instance’s parent coordinate system.

angle - parent_rotation() yields the element’s own rotation relative to its parent, which matches transform-rotation modulo complete turns. Use transform_rotation to retain those turns.

pub fn contains(&self, position: LogicalPoint) -> bool

Returns true if position lies inside the (potentially rotated) rectangle.
