Detailed Description

Wrapper for the wl_region interface.

This class is a convenient wrapper for the wl_region interface. To create a Region call Compositor::createRegion.

The main purpose of this class is to provide regions which can be used to e.g. set the input region on a Surface.

Member Function Documentation

add() [1/2]

void KWayland::Client::Region::add

(

const QRect &

rect

)

Adds the rect to this Region.

Definition at line 99 of file region.cpp.

add() [2/2]

void KWayland::Client::Region::add

(

const QRegion &

region

)

Adds the region to this Rregion.

Definition at line 105 of file region.cpp.

destroy()

void KWayland::Client::Region::destroy

(

)

Destroys the data held by this Region.

This method is supposed to be used when the connection to the Wayland server goes away. If the connection is not valid anymore, it's not possible to call release anymore as that calls into the Wayland connection and the call would fail. This method cleans up the data, so that the instance can be deleted or set up to a new wl_region interface once there is a new connection available.

It is suggested to connect this method to ConnectionThread::connectionDied:

connect(connection, &ConnectionThread::connectionDied, region, &Region::destroy);

release

Definition at line 82 of file region.cpp.

isValid()

bool KWayland::Client::Region::isValid

(

)

const

Returns

true if managing a wl_region.

Definition at line 94 of file region.cpp.

region()

QRegion KWayland::Client::Region::region

(

)

const

The geometry of this Region.

Definition at line 123 of file region.cpp.

release()

void KWayland::Client::Region::release

(

)

Releases the wl_region interface.

After the interface has been released the Region instance is no longer valid and can be setup with another wl_region interface.

Definition at line 77 of file region.cpp.

setup()

void KWayland::Client::Region::setup

(

wl_region *

region

)

Setup this Surface to manage the region.

When using Compositor::createRegion there is no need to call this method.

Definition at line 87 of file region.cpp.

subtract() [1/2]

void KWayland::Client::Region::subtract

(

const QRect &

rect

)

Subtracts rect from this Region.

Definition at line 111 of file region.cpp.

subtract() [2/2]

void KWayland::Client::Region::subtract

(

const QRegion &

region

)

Subtracts region from this Region.

Definition at line 117 of file region.cpp.
