Struct CodeView 

pub struct CodeView<Msg> { /* private fields */ }

Code with syntax colours, line numbers and wrapping of long lines.

While focused, c copies the code to the clipboard and flashes. The code is a text selection region: a mouse drag selects inside it (turn it off with NodeMut::selectable), and clean copies leave out the line numbers. Style keys: code (bg, padding) with focus and pressed; code-line-number; code-token.<kind> where kind is keyword, type, function, macro, string, number, comment, attribute, lifetime, punctuation, table, key or plain.

Implementations

impl<Msg: 'static> CodeView<Msg>

pub fn new(code: impl Into<String>, language: Language) -> Self

Shows code in language.

pub fn line_numbers(self, show: bool) -> Self

Shows or hides line numbers; shown by default.

pub fn on_copy(self, message: Msg) -> Self

Message sent after the code was copied with c.

Trait Implementations

impl<Msg: Clone + 'static> Widget<Msg> for CodeView<Msg>

fn measure(&self, cx: &mut MeasureCx<'_>, available: Size) -> Size

The size the widget wants when it may use up to available.

fn paint(&self, cx: &mut PaintCx<'_>, area: Rect)

Draws the widget into area.

fn event(&self, cx: &mut EventCx<'_, Msg>, event: &Event) -> bool

Handles input. Returns true when the event was used; unused key and scroll events bubble to the parent widget.

fn focusable(&self) -> bool

Whether the widget can take keyboard focus.

fn paint_overlay(&self, _cx: &mut PaintCx<'_>, _anchor: Rect)

Draws the widget’s overlay after the whole view was painted, when it asked for one with PaintCx::request_overlay. anchor is the area the widget was painted in.

fn children(&self) -> &[Node<Msg>]

Child nodes, for widgets that contain other widgets.

fn children_mut(&mut self) -> &mut [Node<Msg>]

Mutable child nodes, used to assign ids.
