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

void KWayland::Client::Region::add ( const QRect rect)

Adds the rect to this Region.

Definition at line 100 of file region.cpp.

void KWayland::Client::Region::add ( const QRegion region)

Adds the region to this Rregion.

Definition at line 106 of file region.cpp.

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:

release

Definition at line 83 of file region.cpp.

bool KWayland::Client::Region::isValid ( ) const
Returns
true if managing a wl_region.

Definition at line 95 of file region.cpp.

QRegion KWayland::Client::Region::region ( ) const

The geometry of this Region.

Definition at line 124 of file region.cpp.

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After the interface has been released the Region instance is no longer valid and can be setup with another wl_region interface.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 78 of file region.cpp.

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 88 of file region.cpp.

void KWayland::Client::Region::subtract ( const QRect rect)

Subtracts rect from this Region.

Definition at line 112 of file region.cpp.

void KWayland::Client::Region::subtract ( const QRegion region)

Subtracts region from this Region.

Definition at line 118 of file region.cpp.
