Constructor & Destructor Documentation

◆ QQuickShapePathPrivate()

QQuickShapePathPrivate::QQuickShapePathPrivate ( )

Describes a Path and associated properties for stroking and filling. 

\qmltype ShapePath

! \instantiates QQuickShapePath \inqmlmodule QtQuick.Shapes

\inherits Path

Since
5.10

A \l Shape contains one or more ShapePath elements. At least one ShapePath is necessary in order to have a Shape output anything visible. A ShapePath itself is a \l Path with additional 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. As with ordinary \l Path objects, ShapePath also contains a list of path elements like \l PathMove, \l PathLine, \l PathCubic, \l PathQuad, \l PathArc, together with a starting position.

Any property changes in these data sets will be bubble up and change the output of the Shape. This means that it is simple and easy to change, or even animate, the starting and ending position, control points, or any stroke or fill parameters using the usual QML bindings and animation types like NumberAnimation.

In the following example the line join style changes automatically based on the value of joinStyleIndex:

\qml ShapePath { strokeColor: "black" strokeWidth: 16 fillColor: "transparent" capStyle: ShapePath.RoundCap

property int joinStyleIndex: 0

property variant styles: [ ShapePath.BevelJoin, ShapePath.MiterJoin, ShapePath.RoundJoin ]

joinStyle: styles[joinStyleIndex]

startX: 30 startY: 30 PathLine { x: 100; y: 100 } PathLine { x: 30; y: 100 } } \endqml

Once associated with a Shape, here is the output with a joinStyleIndex of 2 (ShapePath.RoundJoin):
