Removing row from QAbstractItemModel

[volcano]

Hi all,

I'm using QML treeview with model sub-classed from QAbstractItemModel.
I'm facing this issue that model indexes aren't updated when user removes a row.

Here's the code

bool TreeModel::removeRows(int row, int count, const QModelIndex &parent)
{
	TreeItem *parentItem = getItem(parent);
 
if(parentItem == null) return false;
 
	bool success = false;
 
	if (count > 0)
	{
		beginRemoveRows(parent, row, row + count - 1);
		success = parentItem->removeChildren(row, count);
		endRemoveRows();
	}
 
	return success;
}
 
bool TreeItem::removeChildren(int position, int count)
{
	if (position < 0 || position + count > children_.size())
		return false;
 
	for (int row = 0; row < count; ++row)
		delete children_.takeAt(position);
 
	return true;
}

bool TreeModel::removeRows(int row, int count, const QModelIndex &parent)
{
	TreeItem *parentItem = getItem(parent);

if(parentItem == null) return false;

	bool success = false;

	if (count > 0)
	{
		beginRemoveRows(parent, row, row + count - 1);
		success = parentItem->removeChildren(row, count);
		endRemoveRows();
	}

	return success;
}

bool TreeItem::removeChildren(int position, int count)
{
	if (position < 0 || position + count > children_.size())
		return false;

	for (int row = 0; row < count; ++row)
		delete children_.takeAt(position);

	return true;
}
