Struct State 

pub struct State { /* private fields */ }

Available on crate feature resizable-panel only.

The panels, their sizes and any drag in progress.

Implementations

impl State

pub fn new(panels: impl IntoIterator<Item = Panel>) -> Self

A group of panels at their default sizes.

pub fn with_sizes(self, sizes: impl IntoIterator<Item = f32>) -> Self

Starts from saved sizes, as returned by State::sizes. Sizes of the wrong length or adding up to nothing are ignored; the rest are scaled to add up to 1.

pub fn set_sizes(&mut self, sizes: impl IntoIterator<Item = f32>)

Replaces the sizes, as State::with_sizes does, fitting them to the panels’ limits once the group has been measured.

pub fn step(self, step: Extent) -> Self

How far the arrow keys move a handle. Defaults to 5% of the space.

pub fn large_step(self, step: Extent) -> Self

How far Shift and an arrow key move a handle. Defaults to 20%.

pub fn panels(&self) -> &[Panel]

pub fn sizes(&self) -> Vec<f32>

Each panel’s share of the space, adding up to 1, for saving and restoring with State::with_sizes. Before the group is first measured this is the defaults as fractions, or empty when a default is in pixels.

pub fn total(&self) -> f32

The pixels the panels share, as last measured. 0 before the first measurement.

pub fn is_collapsed(&self, panel: usize) -> bool

pub fn dragging(&self) -> Option<usize>

The handle being dragged, if any.

pub fn resolve(&self, total: f32) -> Vec<f32>

Each panel’s size in pixels, out of total.

pub fn update(&mut self, event: Event) -> Option<Output>

Applies an event and says what changed.

Trait Implementations
