/*!\fn virtual int AbstractRowController::headerHeight() const = 0
* \returns The height of the header part of the view.
*
* Implement this to control how much space is reserved at
* the top of the view for a header
*/
/*!\fn virtual int AbstractRowController::totalHeight() const = 0
* \returns the total height of the rows. For uniformly sized rows that would be
* number_of_rows*row_height.
*/
/*!\fn virtual bool AbstractRowController::isRowVisible( const QModelIndex& idx ) const
* \returns true if the row containing index \a idx is visible
* in the view.
*
* Implement this to allow KDGantt to optimise how items on
* screen are created. It is not harmful to always return true here,
* but the View will not perform optimally.
*/
/*!\fn virtual Span AbstractRowController::rowGeometry( const QModelIndex& idx ) const
* \returns A Span consisting of the row offset and height for the row
* containing \a idx. A simple implementation might look like
*
* \code
* Span MyRowCtrlr::rowGeometry(const QModelIndex& idx)
* {
* return Span(idx.row()*10,10);
* }
* \endcode
