## Detailed Description

A 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 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 Path objects, ShapePath also contains a list of path elements like PathMove, PathLine, PathCubic, PathQuad, 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:

     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 }
     }

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

## Property Documentation

capStyle : enumeration

This property defines how the end points of lines are drawn. The default value is `ShapePath.SquareCap`.

Constant | Description
--- | ---
`ShapePath.FlatCap` | A square line end that does not cover the end point of the line.
`ShapePath.SquareCap` | A square line end that covers the end point and extends beyond it by half the line width.
`ShapePath.RoundCap` | A rounded line end.

dashOffset : real

This property defines the starting point on the dash pattern, measured in units used to specify the dash pattern.

The default value is 0.

See also QPen::setDashOffset().

dashPattern : list<real>

This property defines the dash pattern when ShapePath.strokeStyle is set to ShapePath.DashLine. The pattern must be specified as an even number of positive entries where the entries 1, 3, 5... are the dashes and 2, 4, 6... are the spaces. The pattern is specified in units of the pen's width.

The default value is (4, 2), meaning a dash of 4 * ShapePath.strokeWidth pixels followed by a space of 2 * ShapePath.strokeWidth pixels.

See also QPen::setDashPattern().

fillColor : color

This property holds the fill color.

When set to `transparent`, no filling occurs.

The default value is `white`.

fillGradient : ShapeGradient

This property defines the fill gradient. By default no gradient is enabled and the value is `null`. In this case the fill uses a solid color based on the value of ShapePath.fillColor.

When set, ShapePath.fillColor is ignored and filling is done using one of the ShapeGradient subtypes.

Note: The Gradient type cannot be used here. Rather, prefer using one of the advanced subtypes, like LinearGradient.

fillRule : enumeration

This property holds the fill rule. The default value is `ShapePath.OddEvenFill`. For an explanation on fill rules, see QPainterPath::setFillRule().

Constant | Description
--- | ---
`ShapePath.OddEvenFill` | Odd-even fill rule.
`ShapePath.WindingFill` | Non-zero winding fill rule.

joinStyle : enumeration

This property defines how joins between two connected lines are drawn. The default value is `ShapePath.BevelJoin`.

Constant | Description
--- | ---
`ShapePath.MiterJoin` | The outer edges of the lines are extended to meet at an angle, and this area is filled.
`ShapePath.BevelJoin` | The triangular notch between the two lines is filled.
`ShapePath.RoundJoin` | A circular arc between the two lines is filled.

miterLimit : int

When joinStyle is set to `ShapePath.MiterJoin`, this property specifies how far the miter join can extend from the join point.

The default value is 2.

strokeColor : color

This property holds the stroking color.

When set to `transparent`, no stroking occurs.

The default value is `white`.

strokeStyle : enumeration

This property defines the style of stroking. The default value is ShapePath.SolidLine.

- ShapePath.SolidLine - A plain line.
- ShapePath.DashLine - Dashes separated by a few pixels.

strokeWidth : real

This property holds the stroke width.

When set to a negative value, no stroking occurs.

The default value is 1.
