Changing the set of path elements, changing the properties of these elements, or changing certain properties of the Shape itself all lead to retriangulation of the affected paths on every change.

When the application is running with the generic, triangulation-based Shape implementation, the geometry generation happens entirely on the CPU.

When using Shape, it is important to be aware of potential performance implications:

The OpenVG backend is not currently supported.

The path is rendered via QPainter::strokePath() and QPainter::fillPath() in this case.

The software backend is fully supported.

This converts the shapes into triangles which are passed to the renderer.

When Qt Quick is running with the default, hardware-accelerated backend (RHI), the generic shape renderer will be used.The following list summarizes the available Shape rendering approaches: This is useful since it allows adding visual items, like Rectangle or Image, and non-visual objects, like Timer directly as children of Shape. Like Item, Shape also allows any visual or non-visual objects to be declared as children. Width: 200 height: 150 anchors.centerIn: parent ShapePath See Path for a detailed overview of the supported path elements. Shape's currently supported subset is: PathMove, PathLine, PathQuad, PathCubic, PathArc, PathText and PathSvg. However, not all Shape implementations support all path element types, while some may not make sense for PathView. The types for specifying path elements are shared between PathView and Shape. In addition, the declarative API allows manipulating, binding to, and even animating the path element properties like starting and ending position, the control points, and so on. Therefore Shape is suitable for creating shapes spreading over larger areas of the screen, avoiding the performance penalty for texture uploads or framebuffer blits. This approach is different from rendering shapes via QQuickPaintedItem or the 2D Canvas because the path never gets rasterized in software. Renders a path by triangulating geometry from a QPainterPath. List of all members, including inherited members.
