This event handler, for event event, can be reimplemented to receive mouse double-click events for this item.
When doubleclicking an item, the item will first receive a mouse press event, followed by a release event (i.e., a click), then a double-click event, and finally a release event.
Calling QEvent::ignore() or QEvent::accept() on event has no effect.
The default implementation calls mousePressEvent(). If you want to keep the base implementation when reimplementing this function, call QGraphicsItem::mouseDoubleClickEvent() in your reimplementation.
Note that an item will not receive double click events if it is neither \l {QGraphicsItem::ItemIsSelectable}{selectable} nor \l{QGraphicsItem::ItemIsMovable}{movable} (single mouse clicks are ignored in this case, and that stops the generation of double clicks).

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 double-click 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 \l{QEvent::ignore()}d for items that are neither \l{QGraphicsItem::ItemIsMovable}{movable} nor \l{QGraphicsItem::ItemIsSelectable}{selectable}.

This virtual function receives events to this item. Reimplement this function to intercept events before they are dispatched to the specialized event handlers contextMenuEvent(), focusInEvent(), focusOutEvent(), hoverEnterEvent(), hoverMoveEvent(), hoverLeaveEvent(), keyPressEvent(), keyReleaseEvent(), mousePressEvent(), mouseReleaseEvent(), mouseMoveEvent(), and mouseDoubleClickEvent().
Returns true
if the event was recognized and handled; otherwise, (e.g., if the event type was not recognized,) false is returned.
event is the intercepted event.
