Detailed Description

Default clock face showing local time, date, and companion status. It observes normalized app events and requests only the dynamic region for ordinary minute/media/call changes; the fixed footer is preserved to avoid unnecessary e-paper refresh and ghosting.

Constructor & Destructor Documentation

AppWatchface()

ersa::watchface::AppWatchface::AppWatchface ( )

default

Initialize cached render keys so first paint includes every field.

~AppWatchface()

ersa::watchface::AppWatchface::~AppWatchface ( )

Member Function Documentation

getId()

const char * ersa::watchface::AppWatchface::getId ( ) const

inlineoverridevirtual

Return the stable registry ID used for watchface navigation.

Implements ersa::app::Application.

getPartialBounds()

Rect ersa::watchface::AppWatchface::getPartialBounds ( ) const

inlineoverridevirtual

Return the smallest display rectangle that may have changed. The UI uses this to limit partial e-paper refreshes and reduce visible flashing; return the whole panel when the changed region cannot be bounded. The default describes the 200 by 200 reference canvas and is conservative for the current product; other geometries should provide their own.

Reimplemented from ersa::app::Application.

getTitle()

const char * ersa::watchface::AppWatchface::getTitle ( ) const

inlineoverridevirtual

Return the product-facing watchface label.

Implements ersa::app::Application.

instance()

AppWatchface & ersa::watchface::AppWatchface::instance ( )

static

Return the single static instance registered by the app registry.

onEnter()

void ersa::watchface::AppWatchface::onEnter ( )

overridevirtual

Mark the clock face active and request its initial render.

Reimplemented from ersa::app::Application.

onEvent()

void ersa::watchface::AppWatchface::onEvent ( const events::Event &  event )

overridevirtual

Update cached display state for time, media, call, or notification events.

Reimplemented from ersa::app::Application.

onExit()

void ersa::watchface::AppWatchface::onExit ( )

overridevirtual

Stop face-specific observation when navigating to another app.

Reimplemented from ersa::app::Application.

render()

void ersa::watchface::AppWatchface::render ( hal::IDisplay &  display, bool  fullRefresh  )

overridevirtual

Draw the clock and dynamic companion information using display HAL calls.

Reimplemented from ersa::app::Application.
