Detailed Description

IScreenProvider backed by QGuiApplication::screens().

Standalone consumers (panel applets, notification daemons, lockscreens) use this directly. PlasmaZones injects a virtual-screen-aware provider in its place.

focused() behaviour

Returns primary() by default. Qt does not expose a portable "focused screen" concept — that belongs to the compositor. Subclass and override if your compositor exposes the info via a side channel (KWin's QDBus activeScreen, e.g.).

Member Function Documentation

focused()

QScreen * PhosphorLayer::DefaultScreenProvider::focused ( ) const

overridevirtual

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.

Implements PhosphorLayer::IScreenProvider.

notifier()

ScreenProviderNotifier * PhosphorLayer::DefaultScreenProvider::notifier ( ) const

overridevirtual

Notifier for signal-driven updates.

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

Implements PhosphorLayer::IScreenProvider.

primary()

QScreen * PhosphorLayer::DefaultScreenProvider::primary ( ) const

overridevirtual

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.

Implements PhosphorLayer::IScreenProvider.

screens()

QList< QScreen * > PhosphorLayer::DefaultScreenProvider::screens ( ) const

overridevirtual

Full list of screens the surfaces should be aware of.

Implements PhosphorLayer::IScreenProvider.
