Services

Wakelock

Wakelock service

Create or retrieve this service with page.wakelock(**properties). Ruflet reuses the registered service unless you supply a different id.

Example

status = text(value: "Keeping the screen awake…")
page.add(status)
wakelock = page.wakelock
wakelock.enable(on_result: ->(_result, error) {
  page.update(status, value: error ? error.to_s : "Wakelock enabled")
})

Page accessor

  • page.wakelock(**props)

Properties

  • data — Arbitrary value you can attach to the control and read back in handlers.
  • key — Stable identity used to preserve state across rebuilds.

Page proxy methods

Calling page.wakelock with no properties returns a focused proxy with these methods:

  • disable(timeout: ..., on_result: ...)
  • enable(timeout: ..., on_result: ...)
  • is_enabled(timeout: ..., on_result: ...)

Result and error handling

Client calls are asynchronous. When a method accepts on_result:, handle both callback values: |result, error|. Availability and returned data can vary by platform.

Common service API

The service also supports the common Ruflet control API: attach_handler(event_name, handler), children, emit(event_name, event), has_handler?(event_name), id, merge_props(values = ...), on(event_name, &block), props, runtime_page, runtime_page=, to_patch, type, wire_id, wire_id=.

Use the named methods above for application code; common control methods mainly support event registration, updates, and runtime integration.
