Detailed Description

Represents a Seat on the Wayland Display.

A Seat is a set of input devices (e.g. Keyboard, Pointer and Touch) the client can connect to. The server needs to announce which input devices are supported and passes dedicated input focus to a SurfaceInterface. Only the focused surface receives input events.

The SeatInterface internally handles enter and release events when setting a focused surface. Also it handles input translation from global to the local coordination, removing the need from the user of the API to track the focused surfaces and can just interact with this class.

To create a SeatInterface use Display::createSeat. Then one can set up what is supported. Last but not least create needs to be called.

SeatInterface *seat = display->createSeat();
// set up
seat->setName(QStringLiteral("seat0"));
seat->setHasPointer(true);
seat->setHasKeyboard(true);
seat->setHasTouch(false);
// now fully create
seat->create();

To forward input events one needs to set the focused surface, update time stamp and then forward the actual events:

// example for pointer
seat->setFocusedPointerSurface(surface, QPointF(100, 200)); // surface at it's global position
seat->setTimestamp(100);
seat->notifyPointerMotion(QPointF(350, 210)); // global pos, local pos in surface: 250,10
seat->notifyPointerFrame();
seat->setTimestamp(110);
seat->notifyPointerButton(Qt::LeftButton, PointerButtonState::Pressed);
seat->notifyPointerFrame();
seat->setTimestamp(120);
seat->notifyPointerButton(Qt::LeftButton, PointerButtonState::Released);
seat->notifyPointerFrame();

void KWaylandServer::SeatInterface::relativePointerMotion	(	const QSizeF &	delta,
		const QSizeF &	deltaNonAccelerated,
		quint64	microseconds
	)

A relative motion is in the same dimension as regular motion events, except they do not represent an absolute position.

For example, moving a pointer from (x, y) to (x', y') would have the equivalent relative motion (x' - x, y' - y). If a pointer motion caused the absolute pointer position to be clipped by for example the edge of the monitor, the relative motion is unaffected by the clipping and will represent the unclipped motion.

This method also contains non-accelerated motion deltas (deltaNonAccelerated). The non-accelerated delta is, when applicable, the regular pointer motion delta as it was before having applied motion acceleration and other transformations such as normalization.

Note that the non-accelerated delta does not represent 'raw' events as they were read from some device. Pointer motion acceleration is device- and configuration-specific and non-accelerated deltas and accelerated deltas may have the same value on some devices.

Relative motions are not coupled to wl_pointer.motion events (see setPointerPos, and can be sent in combination with such events, but also independently. There may also be scenarios where wl_pointer.motion is sent, but there is no relative motion. The order of an absolute and relative motion event originating from the same physical motion is not guaranteed.

Sending relative pointer events only makes sense if the RelativePointerManagerInterface is created on the Display.

Parameters

delta	Motion vector
deltaNonAccelerated	non-accelerated motion vector
microseconds	timestamp with microseconds granularity

void KWaylandServer::SeatInterface::setDragTarget	(	SurfaceInterface *	surface,
		const QPointF &	globalPosition,
		const QMatrix4x4 &	inputTransformation
	)

Sets the current drag target to surface.

Sends a drag leave event to the current target and an enter event to surface. The enter position is derived from globalPosition and transformed by inputTransformation.

Definition at line 534 of file seat_interface.cpp.

void KWaylandServer::SeatInterface::setDragTarget	(	SurfaceInterface *	surface,
		const QMatrix4x4 &	inputTransformation = `QMatrix4x4()`
	)

Sets the current drag target to surface.

Sends a drag leave event to the current target and an enter event to surface. The enter position is derived from current global position and transformed by inputTransformation.

Definition at line 572 of file seat_interface.cpp.

void KWaylandServer::SeatInterface::setFocusedKeyboardSurface ( SurfaceInterface * surface )

Passes keyboard focus to surface.

If the SeatInterface has the keyboard capability, also the focused text input surface will be set to surface.

See also: focusedKeyboardSurface; hasKeyboard; setFocusedTextInputSurface

Definition at line 906 of file seat_interface.cpp.

void KWaylandServer::SeatInterface::setFocusedPointerSurface	(	SurfaceInterface *	surface,
		const QPointF &	surfacePosition = `QPoint()`
	)

Sets the focused pointer surface.

All pointer events will be sent to the surface till a new focused pointer surface gets installed. When the focus pointer surface changes a leave event is sent to the previous focused surface.

To unset the focused pointer surface pass nullptr as surface.

Pointer motion events are adjusted to the local position based on the surfacePosition. If the surface changes it's position in the global coordinate system use setFocusedPointerSurfacePosition to update. The surface position is used to create the base transformation matrix to go from global to surface local coordinates. The default generated matrix is a translation with negative surfacePosition.

Parameters

surface	The surface which should become the new focused pointer surface.
surfacePosition	The position of the surface in the global coordinate system

See also: setPointerPos; focucedPointerSurface; focusedPointer; setFocusedPointerSurfacePosition; focusedPointerSurfacePosition; setFocusedPointerSurfaceTransformation; focusedPointerSurfaceTransformation

Definition at line 588 of file seat_interface.cpp.

void KWaylandServer::SeatInterface::setFocusedPointerSurface	(	SurfaceInterface *	surface,
		const QMatrix4x4 &	transformation
	)

Sets the focused pointer surface.

All pointer events will be sent to the surface till a new focused pointer surface gets installed. When the focus pointer surface changes a leave event is sent to the previous focused surface.

To unset the focused pointer surface pass nullptr as surface.

Pointer motion events are adjusted to the local position based on the transformation. If the surface changes it's position in the global coordinate system use setFocusedPointerSurfaceTransformation to update.

Parameters

surface	The surface which should become the new focused pointer surface.
transformation	The transformation to transform global into local coordinates

Definition at line 598 of file seat_interface.cpp.

void KWaylandServer::SeatInterface::setFocusedPointerSurfacePosition ( const QPointF & surfacePosition )

Updates the global position of the currently focused pointer surface.

Updating the focused surface position also generates a new transformation matrix. The default generated matrix is a translation with negative surfacePosition. If a different transformation is required a dedicated call to is required. surfacePosition The new global position of the focused pointer surface focusedPointerSurface setFocusedPointerSurface focusedPointerSurfaceTransformation setFocusedPointerSurfaceTransformation

Definition at line 639 of file seat_interface.cpp.

void KWaylandServer::SeatInterface::setFocusedPointerSurfaceTransformation ( const QMatrix4x4 & transformation )

Sets the transformation for going from global to local coordinates.

The default transformation gets generated from the surface position and reset whenever the surface position changes.

See also: focusedPointerSurfaceTransformation; focusedPointerSurfacePosition; setFocusedPointerSurfacePosition

Definition at line 653 of file seat_interface.cpp.

void KWaylandServer::SeatInterface::setFocusedTextInputSurface ( SurfaceInterface * surface )

Passes text input focus to surface.

If the SeatInterface has the keyboard capability this method will be invoked automatically when setting the focused keyboard surface.

In case there is a TextInputV2Interface for the surface, the enter event will be triggered on the TextInputV2Interface for surface. The focusedTextInput will be set to that TextInputV2Interface. If there is no TextInputV2Interface for that surface, it might get updated later on. In both cases the signal focusedTextInputChanged will be emitted.

See also: focusedTextInputSurface; focusedTextInput; focusedTextInputChanged; setFocusedKeyboardSurface

Definition at line 1196 of file seat_interface.cpp.

void KWaylandServer::SeatInterface::setSelection ( AbstractDataSource * selection )

This method allows to manually set the dataDevice for the current clipboard selection.

The clipboard selection is handled automatically in SeatInterface. If a DataDeviceInterface belonging to the current focused KeyboardInterface sets a selection, the current clipboard selection will be updated automatically. With this method it's possible to override the automatic clipboard update for e.g. the case of a clipboard manager.

Parameters

dataDevice Sets the current clipboard selection.

See also: selection; selectionChanged

Definition at line 1243 of file seat_interface.cpp.

void KWaylandServer::SeatInterface::startPointerPinchGesture ( quint32 fingerCount )

Starts a multi-finch pinch gesture for the currently focused pointer surface.

Such gestures are normally reported through dedicated input devices such as touchpads.

The gesture is usually initiated by multiple fingers moving towards each other or away from each other, or by two or more fingers rotating around a logical center of gravity. The precise conditions of when such a gesture is detected are implementation-dependent.

Only one gesture (either swipe or pinch) can be active at a given time.

Parameters

fingerCount The number of fingers involved in this multi-touch touchpad gesture
