//This will remove all the children of *item*
//Be warned, that the child items won't be deleted!
for(int childcount=0; i<item->childCount(); ++i)
{
	QTreeWidgetItem *currentChildItem = item->child(i);
	item->removeChild(currentChildItem);

	/*
		delete currentChildItem;
		currentChildItem = 0;
	*/
}

//This piece tries to remove *item*
QTreeWidgetItem *rootItem = item->parent(); //We get the parent of item
rootItem->removeChild(item); //Then remove item
