Struct SplitHandle 

pub struct SplitHandle { /* private fields */ }

A bar to drag that changes a size, for a pane an app lays out itself, such as a strip along the bottom of a window. Arrow keys move it too, Shift goes further, and Home and End go to the limits. SplitPanes is built on it.

use ravenrs_layout::Axis;
use ravenrs_reactive::State;
use ravenrs_widgets::{SplitHandle, Ui};

let height = State::new(120.0_f32);
// The strip is below the bar, so it grows as the bar goes up.
let bar = SplitHandle::new(Axis::Vertical, height.binding()).range(80.0, 300.0).inverted();
let mut ui = Ui::new(bar, ravenrs_style::Theme::raven_dark());
ui.update();

Implementations

impl SplitHandle

pub fn new(axis: Axis, value: Binding<f32>) -> SplitHandle

A bar between things laid out along axis, which writes the size it controls to value. It lies across that axis: along Axis::Horizontal, it stands upright.

pub fn range(self, min: f32, max: f32) -> SplitHandle

The smallest and the largest the size can get.

pub fn inverted(self) -> SplitHandle

The size grows as the bar moves left or up, for a pane after the bar.

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

Its name for screen readers (from Labels by default).

pub fn on_end(self, handler: impl Fn() + 'static) -> SplitHandle

Runs when a drag ends or a key moved it, the moment to save the size.

impl View for SplitHandle

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

Creates this view’s node for the current build.

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