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

pub fn new() -> Self

Creates a new empty StackView

pub 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.

pub 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.

pub 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.

pub 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.

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

Adds a view on top of the stack.

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

Adds a view on top of the stack.

Chainable variant.

pub fn pop_layer(&mut self) -> Option<Box<AnyView>>

Remove the top-most layer.

pub fn offset(&self) -> Vec2

Computes the offset of the current top view.

Important traits for Vec<u8>

impl Write for Vec<u8>

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

Returns the size for each layer in this view.

pub fn move_layer(&mut self, from: LayerPosition, to: LayerPosition)

Moves a layer to a new position in the stack.

This only affects the elevation of a layer (whether it is drawn over or under other views).

pub fn move_to_front(&mut self, layer: LayerPosition)

Brings the given view to the front of the stack.

pub fn move_to_back(&mut self, layer: LayerPosition)

Pushes the given view to the back of the stack.

pub fn reposition_layer(&mut self, layer: LayerPosition, position: Position)

Moves a layer to a new position on the screen.

Has no effect on fullscreen layers Has no effect if layer is not found

pub fn draw_bg(&self, printer: &Printer)

Background drawing Drawing functions are split into forground and background to ease inserting layers under the stackview but above it's background you probably just want to call draw()

pub fn draw_fg(&self, printer: &Printer)

Forground drawing Drawing functions are split into forground and background to ease inserting layers under the stackview but above it's background you probably just want to call draw()

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.
