Class: TEgFireGrid
property HeaderHeight: Single;Height of the title row, in FireMonkey units. 0 (the default) keeps the height the active style gives its headers; a positive value replaces it. Negative values are ignored.
The title row does not grow by itself: set HeaderHeight
when the titles need more than one line, with
egoTitleWordWrap in Options or a
column’s SubTitle.
The corner cell above the indicator gutter follows it. The titles are
shown only with egoTitles in Options.
