Detailed Description

Wrapper for the wl_touch interface.

This class is a convenient wrapper for the wl_touch interface.

To create an instance use Seat::createTouch.

Seat

Member Function Documentation

void KWayland::Client::Touch::destroy ( )

Destroys the data held by this Touch.

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_touch interface once there is a new connection available.

This method is automatically invoked when the Seat which created this Touch gets destroyed.

release

Definition at line 248 of file touch.cpp.

void KWayland::Client::Touch::frameEnded ( )
signal

Indicates the end of a contact point list.

bool KWayland::Client::Touch::isValid ( ) const
Returns
true if managing a wl_pointer.

Definition at line 263 of file touch.cpp.

void KWayland::Client::Touch::pointAdded ( KWayland::Client::TouchPoint point)
signal

TouchPoint point got added to the sequence.

void KWayland::Client::Touch::pointMoved ( KWayland::Client::TouchPoint point)
signal

TouchPoint point moved.

void KWayland::Client::Touch::pointRemoved ( KWayland::Client::TouchPoint point)
signal

TouchPoint point is no longer down.

A new TouchPoint might reuse the Id of the point.

void KWayland::Client::Touch::release ( )

Releases the wl_touch interface.

After the interface has been released the Touch instance is no longer valid and can be setup with another wl_touch interface.

This method is automatically invoked when the Seat which created this Touch gets released.

Definition at line 253 of file touch.cpp.

QVector< TouchPoint * > KWayland::Client::Touch::sequence ( ) const

The TouchPoints of the latest touch event sequence.

Only valid till the next touch event sequence is started

Definition at line 278 of file touch.cpp.

void KWayland::Client::Touch::sequenceCanceled ( )
signal

Sent if the compositor decides the touch stream is a global gesture.

void KWayland::Client::Touch::sequenceEnded ( )
signal

Emitted once all touch points are no longer down.

void KWayland::Client::Touch::sequenceStarted ( KWayland::Client::TouchPoint startPoint)
signal

A new touch sequence is started.

The previous sequence is discarded.

Parameters
startPointThe first point which started the sequence
void KWayland::Client::Touch::setup ( wl_touch *  touch)

Setup this Touch to manage the touch.

When using Seat::createTouch there is no need to call this method.
