Struct iced::pure::widget::pane_grid::State

source · [−]

pub struct State<T> {
    pub panes: HashMap<Pane, T, RandomState>,
    pub internal: Internal,
    /* private fields */
}

Available on crate feature pure only.

Expand description

The state of a PaneGrid.

It keeps track of the state of each Pane and the position of each Split.

The State needs to own any mutable contents a Pane may need. This is why this struct is generic over the type T. Values of this type are provided to the view function of PaneGrid::new for displaying each Pane.

Fields

panes: HashMap<Pane, T, RandomState>

The panes of the PaneGrid.

internal: Internal

The internal state of the PaneGrid.

Implementations

source

impl<T> State<T>

source

pub fn new(first_pane_state: T) -> (State<T>, Pane )

Creates a new State, initializing the first pane with the provided state.

Alongside the State, it returns the first Pane identifier.

source

pub fn with_configuration(config: impl Into<Configuration<T>>) -> State<T>

Creates a new State with the given Configuration.

source

pub fn len(&self) -> usize

Returns the total amount of panes in the State.

source

pub fn get(&self, pane: &Pane) -> Option<&T>

Returns the internal state of the given Pane, if it exists.

source

pub fn get_mut(&mut self, pane: &Pane) -> Option<&mut T>

Returns the internal state of the given Pane with mutability, if it exists.

source

pub fn iter(&self) -> impl Iterator<Item = (&Pane, &T)>

Returns an iterator over all the panes of the State, alongside its internal state.

source

pub fn iter_mut(&mut self) -> impl Iterator<Item = (&Pane, &mut T)>

Returns a mutable iterator over all the panes of the State, alongside its internal state.

source

pub fn layout(&self) -> &Node

Returns the layout of the State.

source

pub fn adjacent(&self, pane: &Pane, direction: Direction) -> Option<Pane>

Returns the adjacent Pane of another Pane in the given direction, if there is one.

source

pub fn split(
 &mut self,
 axis: Axis,
 pane: &Pane,
 state: T
) -> Option<(Pane, Split )>

Splits the given Pane into two in the given Axis and initializing the new Pane with the provided internal state.

source

pub fn swap(&mut self, a: &Pane, b: &Pane)

Swaps the position of the provided panes in the State.

If you want to swap panes on drag and drop in your PaneGrid, you will need to call this method when handling a DragEvent.

source

pub fn resize(&mut self, split: &Split, ratio: f32)

Resizes two panes by setting the position of the provided Split.

The ratio is a value in [0, 1], representing the exact position of a Split between two panes.

If you want to enable resize interactions in your PaneGrid, you will need to call this method when handling a ResizeEvent.

source

pub fn close(&mut self, pane: &Pane) -> Option<(T, Pane )>

Closes the given Pane and returns its internal state and its closest sibling, if it exists.
