Detailed Description

Wrapper for zwp_confined_pointer_v1 protocol The confine pointer interface represents a confined pointer state.

This object will send the signal 'confined' when the confinement is activated. Whenever the confinement is activated, it is guaranteed that the surface the pointer is confined to will already have received pointer focus and that the pointer will be within the region passed to the request creating this object. It is up to the compositor to decide whether this requires some user interaction and if the pointer will warp to within the passed region if outside.

To unconfine the pointer, delete the object.

If the compositor decides to unconfine the pointer the unconfined signal is emitted. The ConfinedPointer object is at this point defunct and should be deleted.

Member Function Documentation

void KWayland::Client::ConfinedPointer::confined ( )

signal

Notification that the pointer confinement of the seat's pointer is activated.

See also

unconfined

void KWayland::Client::ConfinedPointer::destroy

(

)

Destroys the data held by this ConfinedPointer.

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 zwp_confined_pointer_v1 interface once there is a new connection available.

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

release

Definition at line 321 of file pointerconstraints.cpp.

bool KWayland::Client::ConfinedPointer::isValid

(

)

const

Returns

true if managing a zwp_confined_pointer_v1.

Definition at line 334 of file pointerconstraints.cpp.

void KWayland::Client::ConfinedPointer::release

(

)

Releases the zwp_confined_pointer_v1 interface.

After the interface has been released the ConfinedPointer instance is no longer valid and can be setup with another zwp_confined_pointer_v1 interface.

Definition at line 316 of file pointerconstraints.cpp.

void KWayland::Client::ConfinedPointer::setRegion

(

Region *

region

)

Set a new region used to confine the pointer.

The new confine region is double-buffered. The new confine region will only take effect when the associated Surface gets its pending state applied. See Surface::commit for details.

If the confinement is active when the new confinement region is applied and the pointer ends up outside of newly applied region, the pointer may warped to a position within the new confinement region. If warped, a Pointer::motion signal will be emitted, but no RelativePointer::relativeMotion signal.

The compositor may also, instead of using the new region, unconfine the pointer.

Parameters

region

The new confine region.

PointerConstraints::confinePointer

Definition at line 339 of file pointerconstraints.cpp.

void KWayland::Client::ConfinedPointer::setup

(

zwp_confined_pointer_v1 *

confinedpointer

)

Setup this ConfinedPointer to manage the confinedpointer.

When using PointerConstraints::createConfinedPointer there is no need to call this method.

Definition at line 311 of file pointerconstraints.cpp.

void KWayland::Client::ConfinedPointer::unconfined ( )

signal

Notification that the pointer confinement of the seat's pointer is no longer active.

If this is a oneshot pointer confinement (see wp_pointer_constraints.lifetime) this object is now defunct and should be destroyed. If this is a persistent pointer confinement (see wp_pointer_constraints.lifetime) this pointer confinement may again reactivate in the future.
