示例1: mouseReleaseEvent

void EmbeddedLinker::mouseReleaseEvent(QGraphicsSceneMouseEvent *event)
{
	hide();
	mMaster->selectionState(false);
	EditorViewScene* scene = dynamic_cast<EditorViewScene*>(mMaster->scene());

	if (!mPressed && scene && mEdge) {
		mEdge->hide();
		QPointF const &eScenePos = event->scenePos();
		NodeElement *under = dynamic_cast<NodeElement*>(scene->itemAt(eScenePos, QTransform()));
		mEdge->show();
		int result = 0;

		commands::CreateElementCommand *createElementFromMenuCommand = NULL;
		if (!under) {
			result = scene->launchEdgeMenu(mEdge, mMaster, eScenePos, false, &createElementFromMenuCommand);
		} else {
			bool canBeConnected = false;
			foreach(PossibleEdge const &pEdge, mEdge->src()->getPossibleEdges()) {
				if (pEdge.first.second.element() == under->id().element()) {
					canBeConnected = true;
				} else {
					// pEdge.second.first is true, if edge can connect items in only one direction.
					if (!pEdge.second.first) {
						canBeConnected = (pEdge.first.first.element() == under->id().element());

				}
			}

			if (under->isContainer()) {

							canBeConnected, &createElementFromMenuCommand);
			} else {

				}
			}
		}
		NodeElement *target = dynamic_cast<NodeElement*>(scene->getLastCreated());

		if (result == -1) {

		} else if ((result == 1) && target) {
			mEdge->setDst(target);
