Struct CachedTextView

pub struct CachedTextView { /* private fields */ }

A simple view showing a fixed text.

Examples

use cursive::Cursive;
use cursive_cached_text_view::CachedTextView;
let mut siv = Cursive::new();

siv.add_layer(CachedTextView::new("Hello world!", 5));

Implementations

impl CachedTextView

pub fn new<S>(content: S, cache_size: usize) -> Self

where S: Into<StyledString>,

Creates a new TextView with the given content.

pub fn new_with_content(content: TextContent, cache_size: usize) -> Self

Creates a new TextView using the given TextContent.

If you kept a clone of the given content, you’ll be able to update it remotely.

Examples

let mut content = TextContent::new("content");
let view = CachedTextView::new_with_content(content.clone(), 5);

// Later, possibly in a different thread
content.set_content("new content");
assert!(view.get_content().source().contains("new"));

pub fn empty() -> Self

Creates a new empty TextView.

pub fn set_style<S: Into<StyleType>>(&mut self, style: S)

Sets the style for the content.

pub fn style<S: Into<StyleType>>(self, style: S) -> Self

Sets the style for the entire content.

Chainable variant.

pub fn no_wrap(self) -> Self

Disables content wrap for this view.

This may be useful if you want horizontal scrolling.

pub fn set_content_wrap(&mut self, wrap: bool)

Controls content wrap for this view.

If true (the default), text will wrap long lines when needed.

pub fn h_align(self, h: HAlign) -> Self

Sets the horizontal alignment for this view.

pub fn v_align(self, v: VAlign) -> Self

Sets the vertical alignment for this view.

pub fn align(self, a: Align) -> Self

Sets the alignment for this view.

pub fn center(self) -> Self

Center the text horizontally and vertically inside the view.

pub fn content<S>(self, content: S) -> Self

where S: Into<StyledString>,

Replace the text in this view.

Chainable variant.

pub fn set_content<S>(&mut self, content: S)

where S: Into<StyledString>,

Replace the text in this view.

pub fn append<S>(&mut self, content: S)

where S: Into<StyledString>,

Append content to the end of a TextView.

pub fn get_content(&self) -> TextContentRef

Returns the current text in this view.

pub fn get_shared_content(&mut self) -> TextContent

Returns a shared reference to the content, allowing content mutation.

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>

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

Returns the type of this view.
