Detailed Description

When writing a QWaylandCompositor in Qt Quick, this class can be used to display a client's contents on an output device and will pass user input to the client.

Member Function Documentation

QWaylandQuickItem::QWaylandQuickItem(QQuickItem *parent = nullptr)

Constructs a QWaylandQuickItem with the given parent.

[signal] void QWaylandQuickItem::surfaceDestroyed()

This signal is emitted when the client has destroyed the wl_surface associated with the QWaylandQuickItem. The handler for this signal is expected to either destroy the QWaylandQuickItem immediately or start a close animation and then destroy the Item.

If an animation is started, bufferLocked should be set to ensure the item keeps its content until the animation finishes

See also QWaylandQuickItem::bufferLocked.

[virtual slot] void QWaylandQuickItem::takeFocus(QWaylandSeat *device = nullptr)

Calling this function causes the item to take the focus of the input device.

[override virtual] QWaylandQuickItem::~QWaylandQuickItem()

Destroy the QWaylandQuickItem.

bool QWaylandQuickItem::inputRegionContains(const QPointF &localPosition) const

Returns true if the input region of this item's surface contains the position given by localPosition.

[invokable, since 5.13] QPointF QWaylandQuickItem::mapFromSurface(const QPointF &point) const

Maps the given point in the Wayland surfaces's coordinate system to the equivalent point within this item's coordinate system, and returns the mapped coordinate.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

This function was introduced in Qt 5.13.

[invokable] QPointF QWaylandQuickItem::mapToSurface(const QPointF &point) const

Maps the given point in this item's coordinate system to the equivalent point within the Wayland surface's coordinate system, and returns the mapped coordinate.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

[invokable] void QWaylandQuickItem::setPrimary()

Makes this QWaylandQuickItem's view the primary view for the surface.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

See also QWaylandSurface::primaryView.

[override virtual] QSGTextureProvider *QWaylandQuickItem::textureProvider() const

Reimplements: QQuickItem::textureProvider() const.

Returns the texture provider of this QWaylandQuickItem.

QWaylandView *QWaylandQuickItem::view() const

Returns the view rendered by this QWaylandQuickItem.
