C++ (Cpp) QueueItem::itemAbove Examples

Example #1

void QueueDialog::btnMoveTop_clicked()
{
	QueueItem* current = (QueueItem*) getCurrentList()->selectedItem();
	if(current == 0)
		return;
	
	if(current->getPriority() == 0)
		return;
	
	QueueItem* previous = (QueueItem*) current->itemAbove();
	
	if(previous == 0)
		return;	
	
	int p = previous->getPriority();
	
	while(previous != 0)
	{
		p = previous->getPriority();
		previous->setPriority(p - 1);
		
		previous = (QueueItem*) previous->itemAbove();
	}
	
	current->setPriority(p);
	getCurrentList()->sort();
}

Example #2

void QueueDialog::writeQueue()
{
	downloadList->sort();
	seedList->sort();
	
	int p = 0;
	
	QueueItem* item = (QueueItem*) downloadList->lastItem();
	if(item != 0)
	{
		while(item != 0)
		{
			if(item->getPriority() != 0)
				item->setTorrentPriority(++p);
			else
				item->setTorrentPriority(0);
			item = (QueueItem*) item->itemAbove();
		}
	}
	
	item = (QueueItem*) seedList->lastItem();
	if(item == 0)
	{
		qman->orderQueue();
		return;
	}
	
	p = 0;
	
	while(item != 0)
	{
		if(item->getPriority() != 0)
			item->setTorrentPriority(++p);
		else
			item->setTorrentPriority(0);
		item = (QueueItem*) item->itemAbove();
	}
	qman->orderQueue();
}
