RowData question or how to replicate RowData.FILLHORIZONTAL

[obender]

Back in the old days there was RowData.FILLHORIZONTAL that would allow for a row of container to be fit in full width horizontally but have a default height.
I've tried to replicate it with new RowData( 1, Style.DEFAULT) but apparently this is not the way it works.
So the question is how to make it mimic the RowData.FILLHORIZONTAL behavior?
