, a certain amount of preprocessing of the input path is performed 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.

QQuickShape::ContainsMode QQuickShape::containsMode | ( | ) | const |
\qmlproperty enumeration QtQuick.Shapes::Shape::containsMode
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.

QQuickShape::RendererType QQuickShape::rendererType | ( | ) | const |
\qmlproperty enumeration QtQuick.Shapes::Shape::rendererType \readonly
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 GPU rendering. Uses the same CPU-based triangulation approach as QPainter's OpenGL 2 paint engine. This is the default when the RHI-based 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 GPU-based renderer that aims to preserve curvature at any scale. In contrast to Shape.GeometryRenderer
, curves are not approximated by short straight lines. Instead, curves are rendered using a specialized fragment shader. This improves visual quality and avoids re-tesselation performance hit when zooming. Also, Shape.CurveRenderer
provides native, high-quality anti-aliasing, without the performance cost of multi- or supersampling.
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
may be requested using the \l preferredRendererType property.
Shape.CurveRenderer
will approximate cubic curves with quadratic ones and may therefore diverge slightly from the mathematically correct visualization of the shape. In addition, if the shape is being rendered into a Qt Quick 3D scene and the OpenGL backend for RHI is active, the GL_OES_standard_derivatives
extension to OpenGL is required (this is available by default on OpenGL ES 3 and later, but optional in OpenGL ES 2.) Definition at line 875 of file qquickshape.cpp.

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.
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.

This function should perform any layout as required for this item.
When polish() is called, the scene graph schedules a polish event for this item. When the scene graph is ready to render this item, it calls updatePolish() to do any item layout as required before it renders the next frame.

\qmlproperty enumeration QtQuick.Shapes::Shape::fillMode
Set this property to define what happens when the path has a different size than the item.
\value Shape.NoResize the shape is rendered at its native size, independent of the size of the item. This is the default \value Shape.Stretch the shape is scaled to fit the item, changing the aspect ratio if necessary. Note that non-uniform scaling may cause reduced quality of anti-aliasing when using the curve renderer \value Shape.PreserveAspectFit the shape is scaled uniformly to fit inside the item \value Shape.PreserveAspectCrop the shape is scaled uniformly to fill the item fully, extending outside the item if necessary.

\qmlproperty enumeration QtQuick.Shapes::Shape::preferredRendererType
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
.
See \l rendererType for more information on the implications.
