Struct cursive::views::StackView

pub struct StackView { /* fields omitted */ }

Simple stack of views. Only the top-most view is active and can receive input.

Methods

impl StackView

fn new() -> Self

Creates a new empty StackView

fn add_fullscreen_layer<T>(&mut self, view: T) where
    T: 'static + View, 

Adds a new full-screen layer on top of the stack.

Fullscreen layers have no shadow.

fn add_layer<T>(&mut self, view: T) where
    T: 'static + View, 

Adds new view on top of the stack in the center of the screen.

fn layer<T>(self, view: T) -> Self where
    T: 'static + View, 

Adds new view on top of the stack in the center of the screen.

Chainable variant.

fn fullscreen_layer<T>(self, view: T) -> Self where
    T: 'static + View, 

Adds a new full-screen layer on top of the stack.

Chainable variant.

fn add_layer_at<T>(&mut self, position: Position, view: T) where
    T: 'static + View, 

Adds a view on top of the stack.

fn layer_at<T>(self, position: Position, view: T) -> Self where
    T: 'static + View, 

Adds a view on top of the stack.

Chainable variant.

fn pop_layer(&mut self)

Remove the top-most layer.

fn offset(&self) -> Vec2

Computes the offset of the current top view.

fn layer_sizes(&self) -> Vec<Vec2>

Returns the size for each layer in this view.

Trait Implementations

impl Default for StackView

fn default() -> Self

Returns the "default value" for a type.

impl View for StackView

fn draw(&self, printer: &Printer)

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

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

Called when a key was pressed.

fn layout(&mut self, size: Vec2)

Called once the size for this view has been decided,

fn required_size(&mut self, size: 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 call_on_any<'a>(
    &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.

fn needs_relayout(&self) -> bool

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