This class provides access to the pointer device in a QWaylandSeat . It corresponds to the Wayland interface wl_pointer.

成员函数文档编制

QWaylandPointer:: QWaylandPointer ( QWaylandSeat * seat , QObject * parent = nullptr)

Constructs a QWaylandPointer for the given seat and with the given parent .

QWaylandCompositor *QWaylandPointer:: compositor () const

Returns the compositor for this QWaylandPointer .

QPointF QWaylandPointer:: currentLocalPosition () const

Returns the current local position of the QWaylandPointer in surface coordinates.

QPointF QWaylandPointer:: currentSpacePosition () const

Returns the current output space position of the QWaylandPointer .

wl_resource *QWaylandPointer:: focusResource () const

Returns a Wayland resource for this QWaylandPointer .

This API doesn't actually make sense, since there may be many pointer resources per client It's here for compatibility reasons.

bool QWaylandPointer:: isButtonPressed () const

Returns true if any button is currently pressed. Otherwise returns false.

注意： Getter function for property isButtonPressed.

QWaylandView *QWaylandPointer:: mouseFocus () const

Returns the view that currently holds mouse focus.

QWaylandOutput *QWaylandPointer:: output () const

Returns the output for this QWaylandPointer .

QWaylandSeat *QWaylandPointer:: seat () const

Returns the input device for this QWaylandPointer .

`[虚拟]` void QWaylandPointer:: sendMouseMoveEvent ( QWaylandView * view , const QPointF & localPos , const QPointF & outputSpacePos )

Sets the current mouse focus to view and sends a mouse move event to it with the local position localPos in surface coordinates and output space position outputSpacePos .

`[虚拟]` uint QWaylandPointer:: sendMousePressEvent ( Qt::MouseButton button )

Sends a mouse press event for button to the view currently holding mouse focus.

Returns the serial number of the press event.

`[虚拟]` uint QWaylandPointer:: sendMouseReleaseEvent ( Qt::MouseButton button )

Sends a mouse release event for button to the view currently holding mouse focus.

Returns the serial number of the release event.

`[虚拟]` void QWaylandPointer:: sendMouseWheelEvent ( Qt::Orientation orientation , int delta )

Sends a mouse wheel event with the given orientation and delta to the view that currently holds mouse focus.

void QWaylandPointer:: setOutput ( QWaylandOutput * output )

Sets the output for this QWaylandPointer to output .
