Convenience method for placing the specified nodes sequentially in a given row of the gridpane. If the row already contains nodes the specified nodes will be appended to the row. For example, the first node will be positioned at [column,row], the second at [column+1,row], etc. This method will set the appropriate gridpane row/column constraints on the nodes as well as add the nodes to the gridpane's children sequence.

Parameters:

rowIndex		the row index position for the children within the gridpane
children		the nodes to be added as a row in the gridpane
