Class: TEgColumn
property SubTitleFont: TFont;Font used to draw SubTitle. Unlike
Title.Font (which belongs to the native
TColumnTitle), SubTitleFont is a genuinely
separate TFont object owned by this column, created with
the column and freed when it is destroyed.
SubTitleFont.Size can never exceed
Title.Font.Size - enforced both when
SubTitleFont itself is changed (a larger value is clamped
down immediately) and again at paint time (covering
Title.Font shrinking afterward, or an OnBeforeDrawTitle
handler pushing either size at paint time). A configured value larger
than Title.Font.Size is not silently lost - only capped for
as long as Title.Font.Size stays smaller; increasing
Title.Font.Size again immediately uncaps it.
Only SubTitleFont.Color, .Size, and
.Bold (via .Style) are ever consulted -
.Name follows whatever this column’s
Title.Font.Name-like default was set to at creation and is
not exposed separately for editing in the TestGrid demo dialog, though
it remains a fully usable TFont property from code.
SubTitleFont.Color is only the starting point for what
is actually drawn: at paint time the color is automatically nudged
lighter or darker if it would otherwise be too low-contrast against the
cell’s own background, so the on-screen result can differ from the
configured value in low-contrast combinations - see OnBeforeDrawTitle
for details.
