Constructor & Destructor Documentation

◆ QQuickTargetDirection()

QT_BEGIN_NAMESPACE QQuickTargetDirection::QQuickTargetDirection ( QObject * parent = nullptr)
explicit

\qmltype TargetDirection \instantiates QQuickTargetDirection \inqmlmodule QtQuick.Particles\inherits Direction

For specifying a direction towards the target point.

\qmlproperty real QtQuick.Particles::TargetDirection::targetX

\qmlproperty real QtQuick.Particles::TargetDirection::targetY

\qmlproperty Item QtQuick.Particles::TargetDirection::targetItem If specified, this will take precedence over targetX and targetY. The targeted point will be the center of the specified Item

\qmlproperty real QtQuick.Particles::TargetDirection::targetVariation

\qmlproperty real QtQuick.Particles::TargetDirection::magnitude

\qmlproperty real QtQuick.Particles::TargetDirection::magnitudeVariation

\qmlproperty bool QtQuick.Particles::TargetDirection::proportionalMagnitude

If true, then the value of magnitude and magnitudeVariation shall be interpreted as multiples of the distance between the source point and the target point, per second.

If false(default), then the value of magnitude and magnitudeVariation shall be interpreted as pixels per second.
