Struct cursive::views::LinearLayout

pub struct LinearLayout { /* fields omitted */ }

Arranges its children linearly according to its orientation.

Methods

impl LinearLayout

pub fn new(orientation: Orientation) -> Self

Creates a new layout with the given orientation.

pub fn weight(self, weight: usize) -> Self

Modifies the weight of the last child added.

It is an error to call this before adding a child (and it will panic).

pub fn child<V: View + 'static>(self, view: V) -> Self

Adds a child to the layout.

Chainable variant.

pub fn add_child<V: View + 'static>(&mut self, view: V)

Adds a child to the layout.

pub fn get_focus_index(&self) -> usize

Returns index of focused inner view

pub fn vertical() -> Self

Creates a new vertical layout.

pub fn horizontal() -> Self

Creates a new horizontal layout.

pub fn get_child(&self, i: usize) -> Option<&AnyView>

Returns a reference to a child.

pub fn get_child_mut(&mut self, i: usize) -> Option<&mut AnyView>

Returns a mutable reference to a child.

Trait Implementations

impl View for LinearLayout

fn draw(&self, printer: &Printer)

Draws the view with the given printer (includes bounds) and focus.

fn needs_relayout(&self) -> bool

Returns true if the view content changed since last layout phase.

fn layout(&mut self, size: Vec2)

Called once the size for this view has been decided,

fn required_size(&mut self, req: Vec2) -> Vec2

Returns the minimum size the view requires with the given restrictions.

fn take_focus(&mut self, source: Direction) -> bool

This view is offered focus. Will it take it?

fn on_event(&mut self, event: Event) -> EventResult

Called when a key was pressed.

    &mut self,
    selector: &Selector,
    callback: Box<FnMut(&mut Any) + 'a>
)

Runs a closure on the view identified by the given selector.

fn focus_view(&mut self, selector: &Selector) -> Result<(), ()>

Moves the focus to the view identified by the given selector.
