Detailed Description

Source-of-truth interface for the available QScreen set.

Abstracted so PlasmaZones can inject a virtual-screen-aware provider (where one physical QScreen may host several logical "screens") while a standalone consumer uses the default QGuiApplication-backed one.

Member Function Documentation

focused()

virtual QScreen * PhosphorLayer::IScreenProvider::focused ( ) const

pure virtual

Screen currently containing the focus / cursor.

Implementations that don't track focus return primary(). Consumers pick between primary() and focused() themselves when constructing a SurfaceConfig; the library does not carry an affinity enum.

Implemented in PhosphorLayer::DefaultScreenProvider.

notifier()

virtual ScreenProviderNotifier * PhosphorLayer::IScreenProvider::notifier ( ) const

pure virtual

Notifier for signal-driven updates.

Pointer is owned by the provider; consumers must not delete it. Lifetime >= the provider's.

Implemented in PhosphorLayer::DefaultScreenProvider.

primary()

virtual QScreen * PhosphorLayer::IScreenProvider::primary ( ) const

pure virtual

Canonical "primary" screen.

SurfaceFactory falls back here when a SurfaceConfig doesn't pin a specific QScreen*. Also used as the recovery target when a bound screen is hot-unplugged.

Implemented in PhosphorLayer::DefaultScreenProvider.

screens()

virtual QList< QScreen * > PhosphorLayer::IScreenProvider::screens ( ) const

pure virtual

Full list of screens the surfaces should be aware of.

Implemented in PhosphorLayer::DefaultScreenProvider.
