◆ mouseMoveEvent()

void QDeclarativeFlickable::mouseMoveEvent ( QGraphicsSceneMouseEvent * event )

protectedvirtual

This event handler, for event event, can be reimplemented to receive mouse move events for this item.

If you do receive this event, you can be certain that this item also received a mouse press event, and that this item is the current mouse grabber.

Calling QEvent::ignore() or QEvent::accept() on event has no effect.

The default implementation handles basic item interaction, such as selection and moving. If you want to keep the base implementation when reimplementing this function, call QGraphicsItem::mouseMoveEvent() in your reimplementation.

Please note that mousePressEvent() decides which graphics item it is that receives mouse events. See the mousePressEvent() description for details.

◆ mousePressEvent()

void QDeclarativeFlickable::mousePressEvent ( QGraphicsSceneMouseEvent * event )

protectedvirtual

This event handler, for event event, can be reimplemented to receive mouse press events for this item.

Mouse press events are only delivered to items that accept the mouse button that is pressed. By default, an item accepts all mouse buttons, but you can change this by calling setAcceptedMouseButtons().

The mouse press event decides which item should become the mouse grabber (see QGraphicsScene::mouseGrabberItem()). If you do not reimplement this function, the press event will propagate to any topmost item beneath this item, and no other mouse events will be delivered to this item.

If you do reimplement this function, event will by default be accepted (see QEvent::accept()), and this item is then the mouse grabber. This allows the item to receive future move, release and doubleclick events. If you call QEvent::ignore() on event, this item will lose the mouse grab, and event will propagate to any topmost item beneath. No further mouse events will be delivered to this item unless a new mouse press event is received.

The default implementation handles basic item interaction, such as selection and moving. If you want to keep the base implementation when reimplementing this function, call QGraphicsItem::mousePressEvent() in your reimplementation.

The event is for items that are neither QGraphicsItem::ItemIsMovable "movable" nor QGraphicsItem::ItemIsSelectable "selectable". mouseMoveEvent(), mouseReleaseEvent(), mouseDoubleClickEvent(), sceneEvent()

◆ sceneEventFilter()

bool QDeclarativeFlickable::sceneEventFilter	(	QGraphicsItem *	watched,

protectedvirtual

Filters events for the item watched.

event is the filtered event.

Reimplementing this function in a subclass makes it possible for the item to be used as an event filter for other items, intercepting all the events send to those items before they are able to respond.

Reimplementations must return true to prevent further processing of a given event, ensuring that it will not be delivered to the watched item, or return false to indicate that the event should be propagated further by the event system.

◆ timerEvent()

void QDeclarativeFlickable::timerEvent ( QTimerEvent * event )

protectedvirtual

This event handler can be reimplemented in a subclass to receive timer events for the object.

QTimer provides a higher-level interface to the timer functionality, and also more general information about timers. The timer event is passed in the event parameter.

Reimplemented from QObject.

◆ wheelEvent()

void QDeclarativeFlickable::wheelEvent ( QGraphicsSceneWheelEvent * event )

protectedvirtual

This event handler, for event event, can be reimplemented to receive wheel events for this item.

If you reimplement this function, event will be accepted by default.

If you ignore the event, (i.e., by calling QEvent::ignore(),) it will propagate to any item beneath this item. If no items accept the event, it will be ignored by the scene, and propagate to the view (e.g., the view's vertical scroll bar).

The default implementation ignores the event.

Reimplemented from QGraphicsItem.
