Class: TEgColumn
procedure RestoreDefaults; override;Clears every one of this unit’s own per-column overrides, in addition
to whatever the inherited TColumn.RestoreDefaults already
resets. Empties AssignedValues,
so all nineteen overridable properties again follow the grid live; also
resets ImageIndex/ TitleImageIndex
to -1, ImageAlignment/
TitleImageAlignment/
Title.Alignment to the same defaults Create sets on a
brand-new column, and SubTitle to
'' - afterwards this column behaves exactly as if it had
just been created. SubTitleFont’s
own styling (Color/Size/Bold) is
left untouched - the same treatment Title.Font already
gets, since RestoreDefaults only resets the “is there a
sub-title at all” state, not cosmetic font sub-properties. Event
properties are left untouched: none of the ten has a “default” to
restore to, only assigned or nil.
