Functions

anticipate(widget, descriptor)

@spec anticipate(widget :: t(), value :: number() | nil) :: t()

Distance in pixels to anticipate visibility.

Accepts number().

build(widget)

@spec build(widget :: t()) :: Plushie.Widget.ui_node()

Converts this widget struct to a ui_node() map. Validates at most one child.

delay(widget, descriptor)

@spec delay(widget :: t(), value :: integer() | nil) :: t()

Delay in milliseconds before emitting events.

Accepts integer().

event_rate(widget, descriptor)

@spec event_rate(widget :: t(), value :: integer() | nil) :: t()

Max events per second for coalescable events.

Accepts integer().

extend(widget, children)

@spec extend(widget :: t(), children :: [Plushie.Widget.child()]) :: t()

Appends multiple children to the widget.

new(id, opts \\ [])

@spec new(id :: String.t(), opts :: [option()]) :: t()

Creates a new widget struct with the given ID and keyword options.

on_resize(widget, descriptor)

@spec on_resize(widget :: t(), value :: (String.t() | atom()) | nil) :: t()

Event tag for resize events.

Accepts String.t() | atom().

push(widget, child)

@spec push(widget :: t(), child :: Plushie.Widget.child()) :: t()

Appends a child to the widget.

sensor(id, opts \\ [])

(macro)

Creates a :sensor widget.

Shorthand for new/2. Import this macro to use the widget name directly in view functions:

import Plushie.Widget.Sensor, only: [sensor: 2]

sensor("my-id", prop: value)

with_options(widget, opts)

@spec with_options(widget :: t(), opts :: [option()]) :: t()

Applies keyword options to an existing widget struct.
