Marquee

Struct Marquee 

Source
pub struct Marquee { /* private fields */ }
Expand description

The animated outline of a selection, the “marching ants”: a dark line with light dashes walking over it, which reads over any picture. Give it a rectangle, a closed path or loose segments, such as the edges of a mask, in the units of the space.

The dashes stop with reduced motion, and then it asks for no frames at all. It takes no input, so what is underneath still gets the pointer.

use ravenrs_core::Rect;
use ravenrs_widgets::Marquee;

let marquee = Marquee::rect(Rect::new(20.0, 20.0, 120.0, 80.0)).size(320.0, 200.0);

Implementations§

Source§

impl Marquee

Source

pub fn rect(rect: Rect) -> Self

Around a rectangle.

Source

pub fn path(points: impl IntoIterator<Item = Point>) -> Self

Along a closed path of these points.

Source

pub fn segments(segments: impl IntoIterator<Item = (Point, Point)>) -> Self

Along separate segments, in any order: the outline of a mask, say.

Source

pub fn animated(self, animated: bool) -> Self

Whether the dashes walk (they do by default, unless motion is reduced).

Source

pub fn label(self, label: impl Into<String>) -> Self

The name screen readers announce, instead of the one in Labels.

Source§

impl Marquee

Source

pub fn size(self, width: f32, height: f32) -> Self

Fixed size in logical pixels, instead of taking the free space.

Source

pub fn grow(self, grow: f32) -> Self

How much of the free space along the parent stack it takes: 1 by default, or 0 over a stage, which then decides the size.

Source

pub fn stage(self, stage: impl View + 'static) -> Self

The view it goes over, such as an Image or a ZoomPanView, which gives it its size. Without one, put it in a ZStack with a fixed size.

Source

pub fn space(self, space: ContentSpace) -> Self

Where the content is, and so the units of its coordinates: by default, its own box.
