Class: TEgColumn
property SubTitle: string;An optional second line rendered below Title.Caption,
using this column’s own SubTitleFont
and the same horizontal alignment as Title.Alignment. Empty
(the default): draws exactly as before, with no layout change at all -
the row height is only taller than usual for a column that actually has
a non-empty SubTitle.
Supports the same <var>VarID</var> and
<br> markers as Title.Caption itself
(see OnGetVariableValue),
including the title-specific rule that <var> never
resolves as a live dataset field. Word-wrap and shrink-to-fit behave the
same way they do for the title line.
Row height: whenever any column in the grid has a
non-empty SubTitle, the title row grows to a fixed
proportion of its usual height to fit both lines, packed together (title
line at the bottom of its own half, SubTitle at the top of
its half). This only happens automatically when TitleRowHeightPx
is not forcing a value and AutoTitleHeight
is off - see that property for the combinations that are not
supported.
SubTitle and its resolved text can be overridden per
paint via OnBeforeDrawTitle’s
SubTitleText parameter - but only to change or blank out an
existing SubTitle, not to grow the row height for
a column whose SubTitle was empty to begin with.
