Class: TEgFireGrid
property RowHeight: Single;Height of every data row, in FireMonkey units. The default is 22;
values below 4 are ignored. All rows have the same height, whatever
their content: a longer text wraps or shrinks within it (see Options), a
picture is shrunk to fit it.
The rows are laid out on whole device pixels, so the value in use may
differ from the property by a fraction of a unit. Raise it together with
Font when the
font is larger; on a touch screen a height of 32 to 40 makes the rows
easier to tap.
