Struct CompareView 

pub struct CompareView { /* private fields */ }

Two pictures to tell apart: side by side, or one over the other with a divider between what shows of each. The divider follows a drag from anywhere, the arrows (with Shift, further), Home and End, and a double click puts it in the middle. A picture that does not have the proportions of the box is fitted in it, centered.

With chosen, side by side, a click or the arrows pick one of the two, which is marked with a check as well as a colored outline.

A drag of the divider paints without a build, so it costs no rebuilds if nothing else reads its position.

use ravenrs_core::{Color, ImageData};
use ravenrs_widgets::{CompareMode, CompareView};

let before = ImageData::from_fn(64, 48, |_, _| Color::rgb(0.3, 0.3, 0.3));
let after = ImageData::from_fn(64, 48, |_, _| Color::rgb(0.6, 0.5, 0.3));
if let (Some(before), Some(after)) = (before, after) {
    let compare = CompareView::new(before, after).mode(CompareMode::Divider).size(480.0, 320.0);
}

Implementations

impl CompareView

pub fn new(first: ImageData, second: ImageData) -> CompareView

Compares two pictures, side by side.

pub fn mode(self, mode: CompareMode) -> CompareView

How it shows them.

pub fn divider(self, divider: Binding<f32>) -> CompareView

Where the divider is, from 0 (all of the second) to 1 (all of the first). Without this it keeps its own, starting in the middle.

pub fn chosen(self, chosen: Binding<CompareSide>) -> CompareView

Which of the two is picked, side by side.

pub fn captions( self, first: impl Into<String>, second: impl Into<String>, ) -> CompareView

What the small captions over the pictures say, instead of those in Labels.

pub fn no_captions(self) -> CompareView

Shows no captions.

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

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

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

How much of the free space along the parent stack it takes (1 by default).

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

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

Trait Implementations

impl View for CompareView

fn build(&self, cx: &mut BuildCx<'_>) -> NodeId

Creates this view’s node for the current build.

fn type_name(&self) -> &'static str

The name the diagnostics panel shows this view’s cost under.
