Member Function Documentation

applyOutputChanges()

bool KWin::OutputBackend::applyOutputChanges ( const OutputConfiguration & config )

virtual

Applies the output changes. Default implementation only sets values common between platforms

Reimplemented in KWin::DrmBackend.

Definition at line 46 of file outputbackend.cpp.

createInputBackend()

std::unique_ptr< InputBackend > KWin::OutputBackend::createInputBackend ( )

virtual

Reimplemented in KWin::DrmBackend, KWin::Wayland::WaylandBackend, and KWin::X11WindowedBackend.

Definition at line 31 of file outputbackend.cpp.

createOpenGLBackend()

std::unique_ptr< OpenGLBackend > KWin::OutputBackend::createOpenGLBackend ( )

virtual

Reimplemented in KWin::DrmBackend, KWin::VirtualBackend, KWin::Wayland::WaylandBackend, KWin::X11StandaloneBackend, and KWin::X11WindowedBackend.

Definition at line 36 of file outputbackend.cpp.

createQPainterBackend()

std::unique_ptr< QPainterBackend > KWin::OutputBackend::createQPainterBackend ( )

virtual

Reimplemented in KWin::DrmBackend, KWin::VirtualBackend, KWin::Wayland::WaylandBackend, and KWin::X11WindowedBackend.

Definition at line 41 of file outputbackend.cpp.

createVirtualOutput()

Output * KWin::OutputBackend::createVirtualOutput ( const QString & name, const QSize & size, qreal scale )

virtual

Definition at line 80 of file outputbackend.cpp.

findOutput()

Output * KWin::OutputBackend::findOutput

(

const QString &

name

)

const

Definition at line 69 of file outputbackend.cpp.

initialize()

virtual bool KWin::OutputBackend::initialize ( )

pure virtual

Implemented in KWin::DrmBackend, KWin::VirtualBackend, KWin::Wayland::WaylandBackend, KWin::X11StandaloneBackend, and KWin::X11WindowedBackend.

outputAdded

void KWin::OutputBackend::outputAdded ( Output * output )

signal

This signal is emitted when an output has been connected. The output is not ready for compositing yet.

outputRemoved

void KWin::OutputBackend::outputRemoved ( Output * output )

signal

This signal is emitted when an output has been disconnected.

outputs()

virtual Outputs KWin::OutputBackend::outputs ( ) const

pure virtual

Implemented in KWin::DrmBackend, KWin::VirtualBackend, KWin::Wayland::WaylandBackend, KWin::X11StandaloneBackend, and KWin::X11WindowedBackend.

outputsQueried

void KWin::OutputBackend::outputsQueried ( )

signal

removeVirtualOutput()

void KWin::OutputBackend::removeVirtualOutput ( Output * output )

virtual

Reimplemented in KWin::DrmBackend, and KWin::Wayland::WaylandBackend.

Definition at line 85 of file outputbackend.cpp.

sceneEglDisplayObject()

virtual EglDisplay * KWin::OutputBackend::sceneEglDisplayObject ( ) const

pure virtual

Implemented in KWin::DrmBackend, KWin::VirtualBackend, KWin::Wayland::WaylandBackend, KWin::X11StandaloneBackend, and KWin::X11WindowedBackend.

sceneEglGlobalShareContext()

EGLContext KWin::OutputBackend::sceneEglGlobalShareContext

(

)

const

Returns the compositor-wide shared EGL context. This function may return EGL_NO_CONTEXT if the underlying rendering backend does not use EGL.

Note that the returned context should never be made current. Instead, create a context that shares with this one and make the new context current.

Definition at line 95 of file outputbackend.cpp.

sceneInitialized

virtual void KWin::OutputBackend::sceneInitialized ( )

inlinevirtualslot

Definition at line 100 of file outputbackend.h.

session()

Session * KWin::OutputBackend::session ( ) const

virtual

Reimplemented in KWin::DrmBackend.

Definition at line 105 of file outputbackend.cpp.

setSceneEglGlobalShareContext()

void KWin::OutputBackend::setSceneEglGlobalShareContext

(

::EGLContext

context

)

Sets the global share context to context. This function is intended to be called only by rendering backends.

Definition at line 100 of file outputbackend.cpp.

supportedCompositors()

virtual QList< CompositingType > KWin::OutputBackend::supportedCompositors ( ) const

pure virtual

The CompositingTypes supported by the Platform. The first item should be the most preferred one.

Since

5.11

Implemented in KWin::DrmBackend, KWin::VirtualBackend, KWin::Wayland::WaylandBackend, KWin::X11StandaloneBackend, and KWin::X11WindowedBackend.

supportInformation()

QString KWin::OutputBackend::supportInformation ( ) const

virtual

A string of information to include in kwin debug output It should not be translated.

The base implementation prints the name.

Since

5.12

Reimplemented in KWin::DrmBackend.

Definition at line 90 of file outputbackend.cpp.
