Struct Editor 

pub struct Editor(/* private fields */);

A multi-line text editor.

Implementations

impl Editor

pub fn new() -> Self

Creates a new empty Editor.

pub fn buffer(&self) -> &Buffer

Returns the buffer of the Editor.

pub fn downgrade(&self) -> Weak

Creates a Weak reference to the Editor.

This is useful to avoid cloning the Editor when referential guarantees are unnecessary. For instance, when creating a rendering tree.

Trait Implementations

impl Debug for Editor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Editor

fn default() -> Self

Returns the “default value” for a type.

impl Editor for Editor

type Font = Font

The font of the Editor.

fn with_text(text: &str) -> Self

Creates a new Editor laid out with the given text.

fn is_empty(&self) -> bool

Returns true if the Editor has no contents.

fn line(&self, index: usize) -> Option<Line<'_>>

Returns the text of the given line in the Editor, if it exists.

fn line_count(&self) -> usize

Returns the amount of lines in the Editor.

fn copy(&self) -> Option<String>

Returns the current selected text of the Editor.

fn selection(&self) -> Selection

Returns the current Selection of the Editor.

fn cursor(&self) -> Cursor

Returns the current Cursor of the Editor.

fn perform(&mut self, action: Action)

Performs an Action on the Editor.

fn move_to(&mut self, cursor: Cursor)

Moves the cursor to the given position.

fn bounds(&self) -> Size

Returns the current boundaries of the Editor.

fn min_bounds(&self) -> Size

Returns the minimum boundaries to fit the current contents of the Editor.

fn hint_factor(&self) -> Option<f32>

Returns the hint factor of the Editor.

fn update( &mut self, new_bounds: Size, new_font: Font, new_size: Pixels, new_line_height: LineHeight, new_wrapping: Wrapping, new_hint_factor: Option<f32>, new_highlighter: &mut impl Highlighter, )

Updates the Editor with some new attributes.

fn highlight<H: Highlighter>( &mut self, font: Self::Font, highlighter: &mut H, format_highlight: impl Fn(&H::Highlight) -> Format<Self::Font>, )

Runs a text Highlighter in the Editor.

impl PartialEq for Editor

fn eq(&self, other: &Editor) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
