◆ control1X()

qreal QQuickPathCubic::control1X ( ) const

\qmltype PathCubic \nativetype QQuickPathCubic \inqmlmodule QtQuick

Defines a cubic Bezier curve with two control points.

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

  • \qml Path { startX: 20; startY: 0 PathCubic { x: 180; y: 0 control1X: -10; control1Y: 90 control2X: 210; control2Y: 90 } } \endqml \endtable

Path, PathQuad, PathLine, PathArc, PathAngleArc, PathCurve, PathSvg, PathRectangle

\qmlproperty real QtQuick::PathCubic::x \qmlproperty real QtQuick::PathCubic::y

Defines the end point of the curve.

See also
relativeX, relativeY

\qmlproperty real QtQuick::PathCubic::relativeX \qmlproperty real QtQuick::PathCubic::relativeY

Defines the end point of the curve 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.
