Method XbpMultiCellGroup():scrollDown() Foundation

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

:scrollDown( <nRows> ) --> nScrolled
This parameter indicates the number of rows to be scrolled.

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


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