Detailed Description

Wrapper for the wl_output interface.

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

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

Output *c = registry->createOutput(name, version);

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

Output *c = new Output;
c->setup(registry->bindOutput(name, version));

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

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

Member Function Documentation

void KWayland::Client::Output::changed ( )

signal

Emitted whenever at least one of the data changed.

void KWayland::Client::Output::destroy

(

)

Destroys the data hold by this Output.

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 380 of file output.cpp.

EventQueue * KWayland::Client::Output::eventQueue

(

)

const

Returns

The event queue to use for bound proxies.

Definition at line 248 of file output.cpp.

QRect KWayland::Client::Output::geometry

(

)

const

The geometry of this Output in pixels.

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

See also

globalPosition

pixelSize

Definition at line 283 of file output.cpp.

Output * KWayland::Client::Output::get ( wl_output *  native )

static

Returns

The Output for the native wl_output. null if there is no Output for it.

Since

5.27

Definition at line 375 of file output.cpp.

QPoint KWayland::Client::Output::globalPosition

(

)

const

Position within the global compositor space.

Definition at line 301 of file output.cpp.

bool KWayland::Client::Output::isValid

(

)

const

Returns

true if managing a wl_output.

Definition at line 347 of file output.cpp.

QString KWayland::Client::Output::manufacturer

(

)

const

Textual description of the manufacturer.

Definition at line 306 of file output.cpp.

void KWayland::Client::Output::modeAdded ( const KWayland::Client::Output::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::Output::modeChanged ( const KWayland::Client::Output::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::Output::model

(

)

const

Textual description of the model.

Definition at line 311 of file output.cpp.

QList< Output::Mode > KWayland::Client::Output::modes

(

)

const

Returns

The Modes of this Output.

Definition at line 362 of file output.cpp.

QSize KWayland::Client::Output::physicalSize

(

)

const

Size in millimeters.

Definition at line 321 of file output.cpp.

QSize KWayland::Client::Output::pixelSize

(

)

const

Size in the current mode.

Definition at line 326 of file output.cpp.

int KWayland::Client::Output::refreshRate

(

)

const

Refresh rate in mHz of the current mode.

Definition at line 334 of file output.cpp.

void KWayland::Client::Output::removed ( )

signal

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

This signal gets only emitted if the Compositor got created by Registry::createOutput

Since

5.5

int KWayland::Client::Output::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.

Definition at line 342 of file output.cpp.

void KWayland::Client::Output::setEventQueue

(

EventQueue *

queue

)

Sets the queue to use for bound proxies.

Definition at line 253 of file output.cpp.

void KWayland::Client::Output::setup

(

wl_output *

output

)

Setup this Compositor to manage the output.

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

Definition at line 243 of file output.cpp.

Output::SubPixel KWayland::Client::Output::subPixel

(

)

const

Subpixel orientation of this Output.

Definition at line 352 of file output.cpp.

Output::Transform KWayland::Client::Output::transform

(

)

const

Transform that maps framebuffer to Output.

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.
