How to set two rows in a table view Horizontal header?

[Barmaglodd]

See Model\View programming in QT docs.

ExampleModel is for data in table. It contains _headerModel. _headerModel discribes header structure.
If you want add rows in table, implement rowCount in Example model (now it returns 0, i.e. no rows), and handle DisplayRole in data.

QVariant data(const QModelIndex& index, int role) const
{
	if(role==Qt::UserRole)
	{
		QVariant v;
		v.setValue((QObject*)&_headerModel);
		return v;
	}
	if(role==Qt::DisplayRole && index.isValid())
	{
		return QString("row %1 column %2").arg(index.row()).arg(index.column());
	}
	return QVariant();
}

QVariant data(const QModelIndex& index, int role) const
{
	if(role==Qt::UserRole)
	{
		QVariant v;
		v.setValue((QObject*)&_headerModel);
		return v;
	}
	if(role==Qt::DisplayRole && index.isValid())
	{
		return QString("row %1 column %2").arg(index.row()).arg(index.column());
	}
	return QVariant();
}

Hi Barmaglodd,
I tried reimplementing the "insertRows" function. Called "beginInsertRows" and "endInsertRows()". But i get lost on what should we put between these two statements inside the function insertRows.

We are trying to insert rows in the example code provided by you before.

Request you to provide us a code snippet on how to insert rows into the table.


With Regards,

Sorry for late answer.
Where do you want to reimplement insertRows? If for table data, i realy recomend you read Model\View programming in Qt docs and Qt demos and examples. If you reimplement it for header model, it's a wrong way, header model is a tree not a table.
