Struct cursive_core::views::ScreensView

pub struct ScreensView<V = BoxedView> { /* private fields */ }

A view that can switch between different screens.

Implementations

impl<V> ScreensView<V>

pub fn new() -> Self

Creates a new empty ScreensView.

pub fn single_screen(v: V) -> Self

Creates a new ScreensView with a single screen.

pub fn screen(&self) -> Option<&V>

Returns a reference to the currently active screen.

Returns None if there is no active screen.

pub fn screen_mut(&mut self) -> Option<&mut V>

Returns a mutable reference to the currently active screen.

pub fn active_screen(&self) -> usize

Returns the id of the currently active screen.

pub fn add_screen(&mut self, v: V) -> usize

Adds a new screen, and returns its ID.

pub fn add_active_screen(&mut self, v: V) -> usize

Convenient method to create a new screen, and set it as active.

pub fn set_active_screen(&mut self, screen_id: usize)

Sets the active screen. Panics if no such screen exist.

impl ScreensView<StackView>

pub fn draw_bg(&self, printer: &Printer<'_, '_>)

Draws the background.

This is mostly used internally by cursive. You probably just want View::draw.

pub fn draw_fg(&self, printer: &Printer<'_, '_>)

Draws the foreground.

This is mostly used internally by cursive. You probably just want View::draw.
