Struct NumberStepperFace 

pub struct NumberStepperFace<'a> { /* private fields */ }

Immediate-mode number stepper: − value +, the face of a NumberInput. Inline (the default) it is the toolbar stepper of NumberInput::compact, bare steppers either side of the value; Self::framed gives the secondary steppers of the framed control, whose value the host’s field draws.

The steppers are squares of the rect’s height at either end; read their geometry from Self::steppers and their pointer targets from Self::hit_rects, so a painted host hit-tests what it painted.

Implementations

impl<'a> NumberStepperFace<'a>

pub fn new(rect: Rect, value: &'a str) -> NumberStepperFace<'a>

An inline stepper in rect showing value (already formatted: a number and its unit, or the host’s own terms such as a clock time).

pub fn names( self, decrease: &'a str, increase: &'a str, ) -> NumberStepperFace<'a>

What the two buttons are called for assistive technology and tooltips, when “Decrease” and “Increase” say less than the host’s own words (“Earlier”, “Later”).

pub fn control_size(self, size: ControlSize) -> NumberStepperFace<'a>

The control size the steppers and the value are set in.

pub fn framed(self) -> NumberStepperFace<'a>

The framed control’s secondary steppers; the value is the host’s field, not painted here.

pub fn hovered(self, part: Option<StepperPart>) -> NumberStepperFace<'a>

The button under the pointer.

pub fn disabled(self, disabled: bool) -> NumberStepperFace<'a>

Unavailable: painted under the disabled alpha.

pub fn height(size: ControlSize, theme: &Theme) -> f64

The control’s height in theme.

pub fn width( size: ControlSize, values: &[&str], text: &mut TextRenderer, theme: &Theme, ) -> f64

The width an inline stepper of size needs so each of values fits between its steppers without the control changing width as it steps. Pass the widest values it can show ("00:00" and "Now").

pub fn steppers(&self) -> (Rect, Rect)

The − and + button faces: squares of the rect’s height.

pub fn value_rect(&self) -> Rect

The run between the steppers where the value sits.

pub fn hit_rects(&self, theme: &Theme) -> (Rect, Rect)

Where a pointer presses each button: its face grown to the minimum target about its centre.

pub fn part_at(&self, theme: &Theme, point: Point) -> Option<StepperPart>

The button under point, by its pointer target.

pub fn paint_steppers(&self, ctx: &mut PaintCtx<'_>)

Paint the two steppers.

pub fn paint_value(&self, ctx: &mut PaintCtx<'_>)

Paint the value centred between the steppers, in the size’s label type with tabular figures.

pub fn paint(&self, ctx: &mut PaintCtx<'_>)

Paint the whole stepper: the steppers and, inline, the value.

Trait Implementations
