◆ asynchronous()

bool QQuickShape::asynchronous ( ) const

\qmlproperty bool QtQuick.Shapes::Shape::asynchronous

When rendererType is Shape.GeometryRenderer, the input path is triangulated on the CPU during the polishing phase of the Shape. This is potentially expensive. To offload this work to separate worker threads, set this property to true.

When enabled, making a Shape visible will not wait for the content to become available. Instead, the GUI/main thread is not blocked and the results of the path rendering are shown only when all the asynchronous work has been finished.

The default value is false.

\qmlmethod bool QtQuick::Item::contains(point point)

Returns true if this item contains point, which is in local coordinates; returns false otherwise. This is the same check that is used for hit-testing a QEventPoint during event delivery, and is affected by \l containmentMask if it is set.

Returns true if this item contains point, which is in local coordinates; returns false otherwise.

This function can be overridden in order to handle point collisions in items with custom shapes. The default implementation checks whether the point is inside \l containmentMask() if it is set, or inside the bounding box otherwise.

Note: This method is used for hit-testing each QEventPoint during event delivery, so the implementation should be kept as lightweight as possible.

◆ containsMode()

QQuickShape::ContainsMode QQuickShape::containsMode ( ) const

\qmlproperty enumeration QtQuick.Shapes::Shape::containsMode

Since: QtQuick.Shapes 1.11

This property determines the definition of \l {QQuickItem::contains()}{contains()} for the Shape. It is useful in case you add \l {Qt Quick Input Handlers} and you want to react only when the mouse or touchpoint is fully inside the Shape.

\value Shape.BoundingRectContains The default implementation of \l QQuickItem::contains() checks only whether the given point is inside the rectangular bounding box. This is the most efficient implementation, which is why it's the default.

\value Shape.FillContains Check whether the interior (the part that would be filled if you are rendering it with fill) of any \l ShapePath that makes up this Shape contains the given point. The more complex and numerous ShapePaths you add, the less efficient this is to check, which can potentially slow down event delivery in your application. So it should be used with care.

One way to speed up the FillContains check is to generate an approximate outline with as few points as possible, place that in a transparent Shape on top, and add your Pointer Handlers to that, so that the containment check is cheaper during event delivery.

◆ rendererType()

QQuickShape::RendererType QQuickShape::rendererType ( ) const

\qmlproperty enumeration QtQuick.Shapes::Shape::rendererType

This property determines which path rendering backend is active.

\value Shape.UnknownRenderer The renderer is unknown.

\value Shape.GeometryRenderer The generic, driver independent solution for OpenGL. Uses the same CPU-based triangulation approach as QPainter's OpenGL 2 paint engine. This is the default when the OpenGL Qt Quick scenegraph backend is in use.

\value Shape.SoftwareRenderer Pure QPainter drawing using the raster paint engine. This is the default, and only, option when the Qt Quick scenegraph is running with the software backend.

\value Shape.CurveRenderer Added as technology preview in Qt 6.6. Experimental renderer which triangulates the polygonal internal hull of the shape, similar to Shape.GeometryRenderer. But instead of also triangulating curved areas, this renderer renders curved areas using a specialized fragment shader. This means that the shape does not need to be re-tesselated when it changes size or is zoomed. For supported shapes, this can give improved runtime performance in cases where the shapes are repeatedly transformed.

By default, Shape.GeometryRenderer will be selected unless the Qt Quick scenegraph is running with the software backend. In that case, Shape.SoftwareRenderer will be used.

Shape.CurveRenderer can be optionally selected using the \l preferredRendererType property.

In addition to rendering smooth curves regardless of zoom level, this renderer applies anti-aliasing without enabling MSAA on the surface, which may provide performance gain.

Note that Shape.CurveRenderer is currently regarded as experimental and has several limitations: \list 1

The GL_OES_standard_derivatives extension to OpenGL is required when the OpenGL RHI backend is in use (this is available by default on OpenGL ES 3 and later, but optional in OpenGL ES 2).
Only quadratic curves are supported (cubic curves will be approximated by quadratic curves).
Shapes where elements intersect are not supported. Use the \l [QML] {Path::simplified} {Path.simplified} property to remove self-intersections from such shapes.
Shapes that span a large numerical range, such as a long string of text, may have issues. Consider splitting these shapes into multiple ones, for instance by making a \l PathText for each individual word. \endlist

Due to the fact that the Shape.CurveRenderer approximates cubic curves, there are certain shapes it will not render accurately. For instance, circular arcs are not representable using quadratic curves and will only look approximately correct. If the visual representation is insufficient for a particular shape, consider using Shape.GeometryRenderer instead.

Note: The Shape.CurveRenderer is currently considered a tech preview, thus the name of this enum may change in future versions of Qt and some shapes may render incorrectly.

◆ updatePaintNode()

QSGNode * QQuickShape::updatePaintNode	(	QSGNode *	oldNode,
		UpdatePaintNodeData *	updatePaintNodeData
	)

overrideprotectedvirtual

Called on the render thread when it is time to sync the state of the item with the scene graph.

The function is called as a result of QQuickItem::update(), if the user has set the QQuickItem::ItemHasContents flag on the item.

The function should return the root of the scene graph subtree for this item. Most implementations will return a single QSGGeometryNode containing the visual representation of this item. oldNode is the node that was returned the last time the function was called. updatePaintNodeData provides a pointer to the QSGTransformNode associated with this QQuickItem.

QSGNode *MyItem::updatePaintNode(QSGNode *node, UpdatePaintNodeData *)
{
    QSGSimpleRectNode *n = static_cast<QSGSimpleRectNode *>(node);
    if (!n) {
        n = new QSGSimpleRectNode();
        n->setColor(Qt::red);
    }
    n->setRect(boundingRect());
    return n;
}

The main thread is blocked while this function is executed so it is safe to read values from the QQuickItem instance and other objects in the main thread.

If no call to QQuickItem::updatePaintNode() result in actual scene graph changes, like QSGNode::markDirty() or adding and removing nodes, then the underlying implementation may decide to not render the scene again as the visual outcome is identical.

Warning: It is crucial that graphics operations and interaction with the scene graph happens exclusively on the render thread, primarily during the QQuickItem::updatePaintNode() call. The best rule of thumb is to only use classes with the "QSG" prefix inside the QQuickItem::updatePaintNode() function.; This function is called on the render thread. This means any QObjects or thread local storage that is created will have affinity to the render thread, so apply caution when doing anything other than rendering in this function. Similarly for signals, these will be emitted on the render thread and will thus often be delivered via queued connections.

Note: All classes with QSG prefix should be used solely on the scene graph's rendering thread. See \l {Scene Graph and Rendering} for more information.

\qmlproperty enumeration QtQuick.Shapes::Shape::preferredRendererType

Since: 6.6

Requests a specific backend to use for rendering the shape. The possible values are the same as for \l rendererType. The default is Shape.UnknownRenderer, indicating no particular preference.

If the requested renderer type is not supported for the current Qt Quick backend, the default renderer for that backend will be used instead. This will be reflected in the \l rendererType when the backend is initialized.

Shape.SoftwareRenderer can currently not be selected without running the scenegraph with the software backend, in which case it will be selected regardless of the preferredRendererType.

Note: This API is considered tech preview and may change or be removed in future versions of Qt.
