Method XbpCellGroup():scrollDown() Foundation

Scrolls cell contents upwards and clears the cells at the bottom.

:scrollDown( <nRows>, [<lRepaint>] ) --> nScrolled
This parameter indicates the number of rows to be scrolled.
<lRepaint> specifies whether or not the cells are immediately re-displayed when the method returns. The default value is .T. (true) and the cells are automatically re-displayed.

The method returns as a numeric value the number of rows that are actually scrolled.


The :scrollDown() method changes the display of the XbpCellGroup object by shifting the cells a specified number of rows upwards. The contents of the cells at the top of the cell group is overwritten while the cells at the bottom become empty. The method :setCell() must be called afterwards to fill the empty cells with values.
