Detailed Description

Wrapper for the org_kde_kwin_outputdevice interface.

This class provides a convenient wrapper for the org_kde_kwin_outputdevice interface. Its main purpose is to hold the information about one OutputDevice.

To use this class one needs to interact with the Registry. There are two possible ways to create an OutputDevice interface:

OutputDevice *c = registry->createOutputDevice(name, version);

This creates the OutputDevice and sets it up directly. As an alternative this can also be done in a more low level way:

OutputDevice *c = new OutputDevice;

c->setup(registry->bindOutputDevice(name, version));

The OutputDevice can be used as a drop-in replacement for any org_kde_kwin_outputdevice pointer as it provides matching cast operators.

Please note that all properties of OutputDevice are not valid until the changed signal has been emitted. The wayland server is pushing the information in an async way to the OutputDevice instance. By emitting changed the OutputDevice indicates that all relevant information is available.

Since: 5.5

Member Function Documentation

void KWayland::Client::OutputDevice::changed ( )

signal

Emitted whenever at least one of the data changed.

OutputDevice::ColorCurves KWayland::Client::OutputDevice::colorCurves ( ) const

Color curves.

Since: 5.50

Definition at line 543 of file outputdevice.cpp.

void KWayland::Client::OutputDevice::colorCurvesChanged ( )

signal

Emitted whenever the color curves changed.

Since: 5.TODO

void KWayland::Client::OutputDevice::destroy ( )

Destroys the data hold by this OutputDevice.

This method is supposed to be used when the connection to the Wayland server goes away. If the connection is not valid any more, it's not possible to call release any more as that calls into the Wayland connection and the call would fail.

This method is automatically invoked when the Registry which created this Output gets destroyed.

Definition at line 548 of file outputdevice.cpp.

void KWayland::Client::OutputDevice::done ( )

signal

Emitted when the output is fully initialized.

QByteArray KWayland::Client::OutputDevice::edid ( ) const

Returns: The EDID information for this output.

Definition at line 528 of file outputdevice.cpp.

QString KWayland::Client::OutputDevice::eisaId ( ) const

Textual representation of EISA identifier.

Definition at line 458 of file outputdevice.cpp.

OutputDevice::Enablement KWayland::Client::OutputDevice::enabled ( ) const

Returns: Whether this output is enabled or not.

Definition at line 533 of file outputdevice.cpp.

void KWayland::Client::OutputDevice::enabledChanged ( OutputDevice::Enablement enabled )

signal

Emitted whenever the enabled property changes.

EventQueue * KWayland::Client::OutputDevice::eventQueue ( ) const

Returns: The event queue to use for bound proxies.

Definition at line 375 of file outputdevice.cpp.

QRect KWayland::Client::OutputDevice::geometry ( ) const

The geometry of this OutputDevice in pixels.

Convenient for QRect(globalPosition(), pixelSize()).

See also: globalPosition; pixelSize

Definition at line 420 of file outputdevice.cpp.

QPoint KWayland::Client::OutputDevice::globalPosition ( ) const

Position within the global compositor space.

Definition at line 438 of file outputdevice.cpp.

bool KWayland::Client::OutputDevice::isValid ( ) const

Returns: true if managing a org_kde_kwin_outputdevice.

Definition at line 500 of file outputdevice.cpp.

QString KWayland::Client::OutputDevice::manufacturer ( ) const

Textual description of the manufacturer.

Definition at line 443 of file outputdevice.cpp.

void KWayland::Client::OutputDevice::modeAdded ( const KWayland::Client::OutputDevice::Mode & mode )

signal

Emitted whenever a new Mode is added.

This normally only happens during the initial promoting of modes. Afterwards only modeChanged should be emitted.

Parameters

mode	The newly added Mode.

See also: modeChanged

void KWayland::Client::OutputDevice::modeChanged ( const KWayland::Client::OutputDevice::Mode & mode )

signal

Emitted whenever a Mode changes.

This normally means that the Mode::Flag::Current is added or removed.

Parameters

mode	The changed Mode

QString KWayland::Client::OutputDevice::model ( ) const

Textual description of the model.

Definition at line 448 of file outputdevice.cpp.

QList< OutputDevice::Mode > KWayland::Client::OutputDevice::modes ( ) const

Returns: The Modes of this OutputDevice.

Definition at line 515 of file outputdevice.cpp.

QSize KWayland::Client::OutputDevice::physicalSize ( ) const

Size in millimeters.

Definition at line 468 of file outputdevice.cpp.

QSize KWayland::Client::OutputDevice::pixelSize ( ) const

Size in the current mode.

Definition at line 473 of file outputdevice.cpp.

int KWayland::Client::OutputDevice::refreshRate ( ) const

Refresh rate in mHz of the current mode.

Definition at line 481 of file outputdevice.cpp.

void KWayland::Client::OutputDevice::removed ( )

signal

The corresponding global for this interface on the Registry got removed.

This signal gets only emitted if the OutputDevice got created by Registry::createOutputDevice

Since: 5.5

int KWayland::Client::OutputDevice::scale ( ) const

Scaling factor of this output.

A scale larger than 1 means that the compositor will automatically scale surface buffers by this amount when rendering. This is used for very high resolution displays where applications rendering at the native resolution would be too small to be legible.

Deprecated:: Since 5.50, use scaleF()

Definition at line 489 of file outputdevice.cpp.

qreal KWayland::Client::OutputDevice::scaleF ( ) const

Scaling factor of this output.

Since: 5.50

Definition at line 494 of file outputdevice.cpp.

QString KWayland::Client::OutputDevice::serialNumber ( ) const

Textual representation of serial number.

Definition at line 453 of file outputdevice.cpp.

void KWayland::Client::OutputDevice::setEventQueue ( EventQueue * queue )

Sets the queue to use for bound proxies.

Definition at line 380 of file outputdevice.cpp.

void KWayland::Client::OutputDevice::setup ( org_kde_kwin_outputdevice * output )

Setup this Compositor to manage the output.

When using Registry::createOutputDevice there is no need to call this method.

Definition at line 370 of file outputdevice.cpp.

OutputDevice::SubPixel KWayland::Client::OutputDevice::subPixel ( ) const

Subpixel orientation of this OutputDevice.

Definition at line 505 of file outputdevice.cpp.

OutputDevice::Transform KWayland::Client::OutputDevice::transform ( ) const

Transform that maps framebuffer to OutputDevice.

The purpose is mainly to allow clients render accordingly and tell the compositor, so that for fullscreen surfaces, the compositor will still be able to scan out directly from client surfaces.

Definition at line 510 of file outputdevice.cpp.

QByteArray KWayland::Client::OutputDevice::uuid ( ) const

Returns: A unique identifier for this outputdevice, determined by the server.

Definition at line 538 of file outputdevice.cpp.

void KWayland::Client::OutputDevice::uuidChanged ( const QByteArray & uuid )

signal

Emitted whenever the id property changes.
