Constructor & Destructor Documentation

◆ QQuickPointerHandlerPrivate()

QQuickPointerHandlerPrivate::QQuickPointerHandlerPrivate ( )

\qmlsignal QtQuick::PointerHandler::grabChanged(PointerDevice::GrabTransition transition, eventPoint point)

This signal is emitted when the grab has changed in some way which is relevant to this handler.

The transition (verb) tells what happened. The point (object) is the point that was grabbed or ungrabbed.

Valid values for transition are:

\value PointerDevice.GrabExclusive This handler has taken primary responsibility for handling the point. \value PointerDevice.UngrabExclusive This handler has given up its previous exclusive grab. \value PointerDevice.CancelGrabExclusive This handler's exclusive grab has been taken over or cancelled. \value PointerDevice.GrabPassive This handler has acquired a passive grab, to monitor the point. \value PointerDevice.UngrabPassive This handler has given up its previous passive grab. \value PointerDevice.CancelGrabPassive This handler's previous passive grab has terminated abnormally.

\qmlsignal QtQuick::PointerHandler::canceled(eventPoint point)

If this handler has already grabbed the given point, this signal is emitted when the grab is stolen by a different Pointer Handler or Item.
