[QLinkedList] find and delete item

[amreo]

I'm the developer of open source project https://github.com/amreo/gridb
I want to implement the deSelect function in src/listcoordselecter.cpp

How to fast way to find and remove item?

I want to find the iterator and remove the related element like

void ListCoordSelecter::deSelect(const Located& loc)
{
	QLinkedList<Located>::iterator iter = this->list.begin();
 
	while (iter.i->n != NULL) 
	{
		if (iter.reference.x() == loc.x() && iter.reference.y == loc.y()) 
		{
			//remove the element pointed by iterator
			break; //end of loop
		}
	}
}

void ListCoordSelecter::deSelect(const Located& loc)
{
	QLinkedList<Located>::iterator iter = this->list.begin();
	
	while (iter.i->n != NULL) 
	{
		if (iter.reference.x() == loc.x() && iter.reference.y == loc.y()) 
		{
			//remove the element pointed by iterator
			break; //end of loop
		}
	}
}
