At least one - VisualPath is necessary in order to have a PathItem output anything - visible. A VisualPath in turn contains a Path and properties describing the - stroking and filling parameters, such as the stroke width and color, the - fill color or gradient, join and cap styles, and so on.

Therefore - PathItem is suitable for creating shapes spreading over larger areas of the - screen, avoiding the performance penalty for texture uploads or framebuffer - blits. In addition, the declarative API allows manipulating, binding to, - and even animating the path element properties like starting and ending - position, the control points, etc. - - The types for specifying path elements are shared between \l PathView and - PathItem. However, not all PathItem implementations support all path - element types, while some may not make sense for PathView. PathItem's - currently supported subset is: PathMove, PathLine, PathQuad, PathCubic, - PathArc, PathSvg. - - See \l Path for a detailed overview of the supported path elements. - - \code - PathItem { - width: 200 - height: 150 - anchors.centerIn: parent - VisualPath { - strokeWidth: 4 - strokeColor: "red" - fillGradient: PathLinearGradient { - x1: 20; y1: 20 - x2: 180; y2: 130 - PathGradientStop { position: 0; color: "blue" } - PathGradientStop { position: 0.2; color: "green" } - PathGradientStop { position: 0.4; color: "red" } - PathGradientStop { position: 0.6; color: "yellow" } - PathGradientStop { position: 1; color: "cyan" } - } - strokeStyle: VisualPath.DashLine - dashPattern: [ 1, 4 ] - Path { - startX: 20; startY: 20 - PathLine { x: 180; y: 130 } - PathLine { x: 20; y: 130 } - PathLine { x: 20; y: 20 } - } - } - } - \endcode - - \image pathitem-code-example.png - - \note It is important to be aware of performance implications, in - particular when the application is running on the generic PathItem - implementation due to not having support for accelerated path rendering. - The geometry generation happens entirely on the CPU in this case, and this - is potentially expensive. Changing the set of path elements, changing the - properties of these elements, or changing certain properties of the - PathItem itself all lead to retriangulation on every change. Therefore, - applying animation to such properties can heavily affect performance on - less powerful systems. If animating properties other than stroke and fill - colors is a must, it is recommended to target systems providing - \c{GL_NV_path_rendering} where the cost of path property changes is much - smaller. - - The following list summarizes the available PathItem rendering approaches: - - \list - - \li When running with the default, OpenGL backend of Qt Quick, both the - generic, triangulation-based and the NVIDIA-specific - \c{GL_NV_path_rendering} methods are available.
