References Clockwise, QQuickSvgParser::pathArc(), positionForCurve(), QPointF::x(), and QPointF::y().

Here is the call graph for this function:

◆ direction()

QQuickPathArc::ArcDirection QQuickPathArc::direction ( ) const

\qmlproperty enumeration QtQuick::PathArc::direction

Defines the direction of the arc. Possible values are PathArc.Clockwise (default) and PathArc.Counterclockwise.

The following QML can produce either of the two illustrated arcs below by changing the value of direction. \table \row

Path {

startX: 50; startY: 50

PathArc {

x: 150; y: 50

radiusX: 75; radiusY: 50

}

}

\endtable

signal

◆ radiusX()

qreal QQuickPathArc::radiusX ( ) const

\qmltype PathArc \instantiates QQuickPathArc \inqmlmodule QtQuick

Defines an arc with the given radius.

PathArc provides a simple way of specifying an arc that ends at a given position and uses the specified radius. It is modeled after the SVG elliptical arc command.

The following QML produces the path shown below: \table \row

Path {

startX: 100; startY: 0

PathArc {

x: 0; y: 100

radiusX: 100; radiusY: 100

useLargeArc: true

}

}

\endtable

Note that a single PathArc cannot be used to specify a circle. Instead, you can use two PathArc elements, each specifying half of the circle.

See also: Path, PathLine, PathQuad, PathCubic, PathAngleArc, PathCurve, PathSvg

\qmlproperty real QtQuick::PathArc::x \qmlproperty real QtQuick::PathArc::y

Defines the end point of the arc.

See also: relativeX, relativeY

\qmlproperty real QtQuick::PathArc::relativeX \qmlproperty real QtQuick::PathArc::relativeY

Defines the end point of the arc relative to its start.

If both a relative and absolute end position are specified for a single axis, the relative position will be used.

Relative and absolute positions can be mixed, for example it is valid to set a relative x and an absolute y.

See also: x, y

\qmlproperty real QtQuick::PathArc::radiusX \qmlproperty real QtQuick::PathArc::radiusY

Defines the radius of the arc.

The following QML demonstrates how different radius values can be used to change the shape of the arc: \table \row

Path {

startX: 0; startY: 100

PathArc {

relativeX: 50; y: 100

radiusX: 25; radiusY: 15

}

PathArc {

relativeX: 50; y: 100

radiusX: 25; radiusY: 25

}

PathArc {

relativeX: 50; y: 100

radiusX: 25; radiusY: 50

}

PathArc {

radiusX: 50; radiusY: 100

}

◆ setXAxisRotation()

void QQuickPathArc::setXAxisRotation ( qreal rotation )

Definition at line 2000 of file qquickpath.cpp.

References QQuickPathElement::changed(), and emit.

Here is the call graph for this function:

◆ useLargeArc()

bool QQuickPathArc::useLargeArc ( ) const

\qmlproperty bool QtQuick::PathArc::useLargeArc Whether to use a large arc as defined by the arc points.

Given fixed start and end positions, radius, and direction, there are two possible arcs that can fit the data. useLargeArc is used to distinguish between these. For example, the following QML can produce either of the two illustrated arcs below by changing the value of useLargeArc.

\table \row

Path {

startX: 0; startY: 100

PathArc {

x: 100; y: 200

radiusX: 100; radiusY: 100

direction: PathArc.Clockwise

}

}

\endtable

The default value is false.

Definition at line 1927 of file qquickpath.cpp.

◆ useLargeArcChanged

void QQuickPathArc::useLargeArcChanged ( )

signal

Referenced by setUseLargeArc().

Here is the caller graph for this function:

◆ xAxisRotation()

qreal QQuickPathArc::xAxisRotation ( ) const

\qmlproperty real QtQuick::PathArc::xAxisRotation

Defines the rotation of the arc, in degrees. The default value is 0.

An arc is a section of circles or ellipses. Given the radius and the start and end points, there are two ellipses that connect the points. This property defines the rotation of the X axis of these ellipses.

Note: The value is only useful when the x and y radius differ, meaning the arc is a section of ellipses.

The following QML demonstrates how different radius values can be used to change the shape of the arc: \table \row

Path {

startX: 50; startY: 100

PathArc {

x: 150; y: 100

radiusX: 50; radiusY: 20

xAxisRotation: 45

}

}
