Detailed Description

Wrapper for the zwp_relative_pointer_v1 interface.

The RelativePointer is an extension to the Pointer used for emitting relative pointer events. It shares the same focus as Pointer of the same Seat and will only emit events when it has focus.

5.28

Member Function Documentation

void KWayland::Client::RelativePointer::destroy

(

)

Destroys the data held by this RelativePointerUnstableV1.

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_relative_pointer_v1 interface once there is a new connection available.

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

Returns

true if managing a zwp_relative_pointer_v1.

void KWayland::Client::RelativePointer::relativeMotion ( const QSizeF &  delta, const QSizeF &  deltaNonAccelerated, quint64  timestamp  )

signal

A relative motion event.

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 signal 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 Pointer motion events, and can be sent in combination with such events, but also independently. There may also be scenarios where 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.

Parameters

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

void KWayland::Client::RelativePointer::release

(

)

Releases the zwp_relative_pointer_v1 interface.

After the interface has been released the RelativePointerUnstableV1 instance is no longer valid and can be setup with another zwp_relative_pointer_v1 interface.

Definition at line 156 of file relativepointer.cpp.

void KWayland::Client::RelativePointer::setup

(

zwp_relative_pointer_v1 *

relativepointerunstablev1

)

Setup this RelativePointerUnstableV1 to manage the relativepointerunstablev1.

When using RelativePointerManagerUnstableV1::createRelativePointerUnstableV1 there is no need to call this method.
