Struct cursive_extras::ImageView

pub struct ImageView { /* private fields */ }

View that can render a low res image as text

It is highly recommended to use buffered_backend_root() to create the cursive root, otherwise this view may mess up the terminal color scheme

Implementations

impl ImageView

pub fn new(width: usize, height: usize) -> ImageView

Create a new empty ImageView

pub fn set_image(&mut self, path: &str)

Set the image to render

pub fn image(self, path: &str) -> ImageView

Set the image to render

Chainable version

pub fn set_size(&mut self, new_width: usize, new_height: usize)

Set the rendering size of the image

Size is measured in terminal cells

pub fn get_path(&self) -> &str

Gets the path of the image

Trait Implementations

impl View for ImageView

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

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

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

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

fn layout(&mut self, _: XY<usize>)

Called once the size for this view has been decided.

fn needs_relayout(&self) -> bool

Should return true if the view content changed since the last call to layout().

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

Called when an event is received (key press, mouse event, …).

fn call_on_any( &mut self, _: &Selector<'_>, _: &mut dyn FnMut(&mut (dyn View + 'static)) )

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

fn focus_view(&mut self, _: &Selector<'_>) -> Result<EventResult, ViewNotFound>

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

fn take_focus(&mut self, source: Direction) -> Result<EventResult, CannotFocus>

Attempt to give this view the focus.

fn important_area(&self, view_size: XY<usize>) -> Rect

What part of the view is important and should be visible?

fn type_name(&self) -> &'static str

Returns the type of this view.
