Struct Logo 

pub struct Logo;

The QCode wordmark.

Drawn from block elements where the terminal has them. ASCII has no block elements and a shape spelled out of # or = would be a text ornament, so in that mode the lit cells are painted in the accent colour instead, which rounds every half block up to a whole cell.

The drawing gives way before the menu does: without the room for it the name is written plainly, and without the room for that either nothing is drawn.

Give the logo Logo::WIDTH cells of width. It centres whichever form it draws inside the area it is given, so a narrower area still holds the name in the middle.

Implementations

impl Logo

pub const WIDTH: u16 = 44

Cells the drawing takes across, and the width the logo is laid out with.

pub fn new() -> Self

The wordmark.

Trait Implementations

impl Clone for Logo

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Logo

impl Debug for Logo

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

Formats the value using the given formatter.

impl Default for Logo

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Logo

impl PartialEq for Logo

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for Logo

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

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 keys(&self, _env: &Env) -> Vec<WidgetKey>

The keys this widget takes while it has keyboard focus, as the HelpLayer lists them at the top of its “This screen” group. Nothing by default: a widget with no keys of its own says nothing.

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.
