How to detect drop is between two items or on one item in QTreeView?

[derhexer]

Hi,

i'm using QTreeView connected to a QStandardItemModel (which is based on sqlite database). I want support full drag and drop. So i have to know if a drop is released on one item or between two items. How can i detect this?

Thanks for any help and hint!

I solved it...

bool MyModel::dropMimeData(const QMimeData *data, Qt::DropAction action, int row, int column, const QModelIndex &parent)
{
	if (parent.isValid())
	{
		QStandardItem *itemTo = itemFromIndex(parent);
		if (row < 0) //dropped on item
			qDebug() << "append as child to item: " << itemTo->data().toInt();
		else //dropped between two items
		{
			QModelIndex insert = parent.child(row, column);
			itemTo = itemFromIndex(insert);
			qDebug() << "insert as sibling before: " << itemTo->data().toInt();
		}
	}
 ....
}

bool MyModel::dropMimeData(const QMimeData *data, Qt::DropAction action, int row, int column, const QModelIndex &parent)
{
	if (parent.isValid())
	{
		QStandardItem *itemTo = itemFromIndex(parent);
		if (row < 0) //dropped on item
			qDebug() << "append as child to item: " << itemTo->data().toInt();
		else //dropped between two items
		{
			QModelIndex insert = parent.child(row, column);
			itemTo = itemFromIndex(insert);
			qDebug() << "insert as sibling before: " << itemTo->data().toInt();
		}
	}
