Making Table cell as a combobox?

[kaushal_gaurav]

I have implemented data as

QVariant className::data(const QModelIndex & index, int role) const
{
	if( index.isValid() == false )
		return QVariant();
 
	if( role == Qt::EditRole )
	{
		if( index.internalPointer() )
		{
			int parentRow = ipToRow(index.internalPointer());
			return QString("Cell %3.%1.%2").arg(index.row()).arg(index.column())
				.arg(parentRow);
		}
 
		return QString("Cell %1.%2").arg(index.row()).arg(index.column());
	}

QVariant className::data(const QModelIndex & index, int role) const
{
	if( index.isValid() == false )
		return QVariant();

	if( role == Qt::EditRole )
	{
		if( index.internalPointer() )
		{
			int parentRow = ipToRow(index.internalPointer());
			return QString("Cell %3.%1.%2").arg(index.row()).arg(index.column())
				.arg(parentRow);
		}

		return QString("Cell %1.%2").arg(index.row()).arg(index.column());
	}

To copy to clipboard, switch view to plain text mode 

and Flags() as

Qt::ItemFlags className::flags( const QModelIndex& idx ) const
{
 
	return Qt::ItemIsEditable;
}

Qt::ItemFlags className::flags( const QModelIndex& idx ) const
{

	return Qt::ItemIsEditable;
}

To copy to clipboard, switch view to plain text mode 

but it did not work.

did i do something wrong...?

Qt::ItemFlags className::flags( const QModelIndex& idx ) const
{
 
	return Qt::ItemIsEditable;
}

Qt::ItemFlags className::flags( const QModelIndex& idx ) const
{

	return Qt::ItemIsEditable;
}

To copy to clipboard, switch view to plain text mode 

This would mean that all items are disabled, thus non-editable. Try something like:

Qt::ItemFlags className::flags(const QModelIndex &index) const
{
    if (!index.isValid())
        return 0;
 
    return Qt::ItemIsSelectable|Qt::ItemIsEnabled|Qt::ItemIsEditable;
}

Qt::ItemFlags className::flags(const QModelIndex &index) const
{
    if (!index.isValid())
        return 0;

    return Qt::ItemIsSelectable|Qt::ItemIsEnabled|Qt::ItemIsEditable;
}

To copy to clipboard, switch view to plain text mode

Hi,
use QAbstractItemView::openPersistentEditor.
