Struct GlyphSample 

pub struct GlyphSample { /* private fields */ }

A few icons drawn in one GlyphMode, whatever mode the application draws in.

No program can learn which font a terminal draws with, so the last word on Nerd Font glyphs is the user’s eye: a setup screen puts a Nerd sample beside a Unicode one and asks which reads as shapes. A missing Nerd Font shows as boxes or question marks. Place one after installing the font (see nerd_font) to show whether the terminal picked it up.

use qframe::icons::{GlyphMode, GlyphSample};

let nerd = GlyphSample::new(GlyphMode::Nerd);
let unicode = GlyphSample::new(GlyphMode::Unicode).keys(["folder", "check"]);

The glyphs come from the active icon set, so a theme’s icons show as they would be drawn. They use the text colour on no background of their own.

Implementations

impl GlyphSample

pub const KEYS: [&str; 4]

The icons shown unless GlyphSample::keys names others: four whose Nerd glyphs lie in the private use area, so none of them looks right without a Nerd Font.

pub fn new(mode: GlyphMode) -> Self

A sample of GlyphSample::KEYS in mode.

pub fn keys(self, keys: impl IntoIterator<Item = impl Into<String>>) -> Self

Shows these icon keys instead, in order. A key the icon set lacks is left out.

Trait Implementations

impl Clone for GlyphSample

fn clone(&self) -> GlyphSample

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GlyphSample

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

Formats the value using the given formatter.

impl Eq for GlyphSample

impl PartialEq for GlyphSample

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for GlyphSample

impl<Msg: 'static> Widget<Msg> for GlyphSample

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 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 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 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.
