Detailed Description

This class is a wrapper for the zwp_pointer_gesture_swipe_v1 protocol.

A PointerSwipeGesture object notifies a client about a multi-finger swipe gesture detected on an indirect input device such as a touchpad. The gesture is usually initiated by multiple fingers moving in the same direction but once initiated the direction may change. The precise conditions of when such a gesture is detected are implementation-dependent.

A gesture consists of three stages: begin, update (optional) and end. There cannot be multiple simultaneous pinch or swipe gestures on the same pointer/seat, how compositors prevent these situations is implementation-dependent.

A gesture may be cancelled by the compositor or the hardware. Clients should not consider performing permanent or irreversible actions until the end of a gesture has been received.

Member Function Documentation

void KWayland::Client::PointerSwipeGesture::cancelled	(	quint32	serial,
		quint32	time
	)

signal

A gesture got cancelled by the Wayland compositor.

Parameters

serial	Unique serial for this cancel gesture event.
time	Timestamp in milliseconds granularity

See also: started; updated; ended

void KWayland::Client::PointerSwipeGesture::destroy ( )

Destroys the data held by this PointerSwipeGesture.

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_pointer_gesture_swipe_v1 interface once there is a new connection available.

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

connect(connection, &ConnectionThread::connectionDied, pointerswipegesture, &PointerSwipeGesture::destroy);

See also: release

Definition at line 204 of file pointergestures.cpp.

void KWayland::Client::PointerSwipeGesture::ended	(	quint32	serial,
		quint32	time
	)

signal

A gesture ended.

Parameters

serial	Unique serial for this end gesture event.
time	Timestamp in milliseconds granularity

See also: started; updated; cancelled

quint32 KWayland::Client::PointerSwipeGesture::fingerCount ( ) const

The number of fingers taking part in this gesture.

If no gesture is in progress 0 is returned.

Definition at line 176 of file pointergestures.cpp.

bool KWayland::Client::PointerSwipeGesture::isValid ( ) const

Returns: true if managing a zwp_pointer_gesture_swipe_v1.

Definition at line 217 of file pointergestures.cpp.

void KWayland::Client::PointerSwipeGesture::release ( )

Releases the zwp_pointer_gesture_swipe_v1 interface.

After the interface has been released the PointerSwipeGesture instance is no longer valid and can be setup with another zwp_pointer_gesture_swipe_v1 interface.

Definition at line 199 of file pointergestures.cpp.

void KWayland::Client::PointerSwipeGesture::setup ( zwp_pointer_gesture_swipe_v1 * pointerswipegesture )

Setup this PointerSwipeGesture to manage the pointerswipegesture.

When using PointerGestures::createPointerSwipeGesture there is no need to call this method.

Definition at line 194 of file pointergestures.cpp.

void KWayland::Client::PointerSwipeGesture::started	(	quint32	serial,
		quint32	time
	)

signal

A gesture got started.

Parameters

serial	Unique serial for this start gesture event.
time	Timestamp in milliseconds granularity

See also: updated; ended; cancelled

QPointer< Surface > KWayland::Client::PointerSwipeGesture::surface ( ) const

The Surface on which this gesture is performed.

If no gesture is in progress the returned pointer is null.

Definition at line 181 of file pointergestures.cpp.

void KWayland::Client::PointerSwipeGesture::updated	(	const QSizeF &	delta,
		quint32	time
	)

signal

A gesture got updated.

Parameters

delta	relative coordinates of the logical center of the gesture compared to the previous event
time	Timestamp in milliseconds granularity

See also: started; ended; cancelled
