    public class QPainterPathStroker

extends QtJambiObject

The QPainterPathStroker class is used to generate fillable outlines for a given painter path. By calling the `createStroke()` function, passing a given `QPainterPath` as argument, a new painter path representing the outline of the given path is created. The newly created painter path can then be filled to draw the original painter path's outline.

You can control the various design aspects (width, cap styles, join styles and dash pattern) of the outlining using the following functions:

- `setWidth()`
- `setCapStyle()`
- `setJoinStyle()`
- `setDashPattern()`

The `setDashPattern()` function accepts both a `Qt::PenStyle` object and a vector representation of the pattern as argument.

In addition you can specify a curve's threshold, controlling the granularity with which a curve is drawn, using the `setCurveThreshold()` function. The default threshold is a well adjusted value (0.25), and normally you should not need to modify it. However, you can make the curve's appearance smoother by decreasing its value.

You can also control the miter limit for the generated outline using the `setMiterLimit()` function. The miter limit describes how far from each join the miter join can extend. The limit is specified in the units of width so the pixelwise miter limit will be `miterlimit * width`. This value is only used if the join style is `Qt::MiterJoin` .

The painter path generated by the `createStroke()` function should only be used for outlining the given painter path. Otherwise it may cause unexpected behavior. Generated outlines also require the `Qt::WindingFill` rule which is set by default.

  `QPen`, and `QBrush`.

Constructor Detail

### QPainterPathStroker

    public QPainterPathStroker()

  Creates a new stroker.

Method Detail

### capStyle

    public final Qt.PenCapStyle capStyle()

  Returns the cap style of the generated outlines.

See also:
  `setCapStyle()`.

### createStroke

    public final QPainterPath createStroke(QPainterPath path)

  Generates a new path that is a fillable area representing the outline of the given `path`.

  The various design aspects of the outline are based on the stroker's properties: `width()`, `capStyle()`, `joinStyle()`, `dashPattern()`, `curveThreshold()` and `miterLimit()`.

  The generated path should only be used for outlining the given painter path. Otherwise it may cause unexpected behavior. Generated outlines also require the `Qt::WindingFill` rule which is set by default.

### curveThreshold

    public final double curveThreshold()

  Returns the curve flattening threshold for the generated outlines.

See also:
  `setCurveThreshold()`.

### dashOffset

    public final double dashOffset()

  Returns the dash offset for the generated outlines.

See also:
  `setDashOffset()`.

### dashPattern

    public final java.util.List dashPattern()

  Returns the dash pattern for the generated outlines.

See also:
  `setDashPattern()`.

### joinStyle

    public final Qt.PenJoinStyle joinStyle()

  Returns the join style of the generated outlines.

See also:
  `setJoinStyle()`.

### miterLimit

    public final double miterLimit()

  Returns the miter limit for the generated outlines.

See also:
  `setMiterLimit()`.

### setCapStyle

    public final void setCapStyle(Qt.PenCapStyle style)

  Sets the cap style of the generated outlines to `style`. If a dash pattern is set, each segment of the pattern is subject to the cap `style`.

See also:
  `capStyle()`.

### setCurveThreshold

    public final void setCurveThreshold(double threshold)

  Specifies the curve flattening `threshold`, controlling the granularity with which the generated outlines' curve is drawn.

  The default threshold is a well adjusted value (0.25), and normally you should not need to modify it. However, you can make the curve's appearance smoother by decreasing its value.

See also:
  `curveThreshold()`.

### setDashOffset

    public final void setDashOffset(double offset)

  Sets the dash offset for the generated outlines to `offset`.

See also:
  `dashOffset()`.

### setDashPattern

    public final void setDashPattern(Qt.PenStyle arg__1)

  Sets the dash pattern for the generated outlines to `style`.

See also:
  `dashPattern()`.

### setDashPattern

    public final void setDashPattern(java.util.List dashPattern)

  Sets the dash pattern for the generated outlines to `dashPattern`. This function makes it possible to specify custom dash patterns.

  Each element in the vector contains the lengths of the dashes and spaces in the stroke, beginning with the first dash in the first element, the first space in the second element, and alternating between dashes and spaces for each following pair of elements.

  The vector can contain an odd number of elements, in which case the last element will be extended by the length of the first element when the pattern repeats.

### setJoinStyle

    public final void setJoinStyle(Qt.PenJoinStyle style)

  Sets the join style of the generated outlines to `style`.

See also:
  `joinStyle()`.

### setMiterLimit

    public final void setMiterLimit(double length)

  Sets the miter limit of the generated outlines to `limit`.

  The miter limit describes how far from each join the miter join can extend. The limit is specified in units of the currently set width. So the pixelwise miter limit will be `miterlimit * width`.

  This value is only used if the join style is `Qt::MiterJoin` .

See also:
  `miterLimit()`.

### setWidth

    public final void setWidth(double width)

  Sets the width of the generated outline painter path to `width`.

  The generated outlines will extend approximately 50% of `width` to each side of the given input path's original outline.

See also:
  `width()`.

### width

    public final double width()

  Returns the width of the generated outlines.

See also:
  `setWidth()`.
