Detailed Description

Resource representing a wl_surface.

The SurfaceInterface gets created by the CompositorInterface. A SurfaceInterface normally takes up a role by being "attached" to either a ShellSurfaceInterface, a SubSurfaceInterface or a Cursor.

The implementation of the SurfaceInterface does not only wrap the features exposed by wl_surface, but goes further by integrating the information added to a SurfaceInterface by other interfaces. This should make interacting from the server easier, it only needs to monitor the SurfaceInterface and does not need to track each specific interface.

The SurfaceInterface takes care of reference/unreferencing the BufferInterface attached to it. As long as a BufferInterface is attached, the released signal won't be sent. If the BufferInterface is no longer needed by the SurfaceInterface, it will get unreferenced and might be automatically deleted (if it's no longer referenced).

If no such SurfaceInterface is found, e.g. because the SurfaceInterface is unmapped or there is no input region containing the position, nullptr is returned.

Parameters

See also
confinedPointer
lockedPointer
Since
5.29

◆ resetTrackedDamage()

void KWayland::Server::SurfaceInterface::resetTrackedDamage ( )

Reset the damage tracking.

The compositor should invoke this method once it updated it's internal state and processed the current damage.

See also
trackedDamage
Since
5.22

Definition at line 811 of file surface_interface.cpp.

◆ setDataProxy()

void KWayland::Server::SurfaceInterface::setDataProxy ( SurfaceInterface *  surface)

Set surface as a data proxy for this SurfaceInterface.

This enables the proxy to conduct drags on the surface's client behalf.

Setting a data proxy is only allowed when the client owning this surface has not created a data device itself.

Since

5.27

Definition at line 823 of file surface_interface.cpp.

◆ shadow()

Definition at line 788 of file surface_interface.cpp.

◆ slideOnShowHideChanged

signal
Since
5.5

◆ subSurface()

QPointer< SubSurfaceInterface > KWayland::Server::SurfaceInterface::subSurface ( ) const
Returns
The SubSurface for this Surface in case there is one.

Definition at line 741 of file surface_interface.cpp.

◆ subSurfaceTreeChanged

void KWayland::Server::SurfaceInterface::subSurfaceTreeChanged ( )
signal

Emitted whenever the tree of sub-surfaces changes in a way which requires a repaint.

Since
5.22

◆ surfaceAt()

SurfaceInterface * KWayland::Server::SurfaceInterface::surfaceAt ( const QPointF &  position)

Finds the SurfaceInterface at the given position in surface-local coordinates.

This can be either a descendant SurfaceInterface honoring the stacking order or the SurfaceInterface itself if its geometry contains the given position.

If no such SurfaceInterface is found, e.g. because the SurfaceInterface is unmapped, nullptr is returned.

Parameters
positionThe position in surface-local coordinates
Returns
Child surface at the given position or surface itself at the position, might be nullptr
Since
5.22

Definition at line 862 of file surface_interface.cpp.

◆ trackedDamage()

QRegion KWayland::Server::SurfaceInterface::trackedDamage ( ) const

Returns the tracked damage since the last call to resetTrackedDamage.

In contrast to damage this method does not reset the damage when a new BufferInterface gets committed. This allows a compositor to properly track the damage over multiple commits even if it didn't render each new BufferInterface.

The damage gets reset whenever resetTrackedDamage is called. This allows a compositor to properly track the change in its rendering scene for this SurfaceInterface. After it updates its internal state (e.g. by creating an OpenGL texture from the BufferInterface) it can invoke resetTrackedDamage and the damage tracker will start to track further damage changes.

Returns
Combined damage since last call to resetTrackedDamage

Since
5.22

Definition at line 805 of file surface_interface.cpp.

◆ unmapped

void KWayland::Server::SurfaceInterface::unmapped ( )
signal

Emitted when the Surface removes its content.
