Class: TEgColumn
constructor Create(Collection: TCollection); override;Standard column constructor, called whenever a
TEgDBGridEx adds a new column (design time or at runtime).
Seeds ImageIndex and
TitleImageIndex
to -1 (“no image” - a plain Integer field’s
ordinary zero-init would otherwise be mistaken for the first image in Images), and sets
ImageAlignment/
TitleImageAlignment
to taRightJustify and the inherited
Title.Alignment to taCenter - matching the
same defaults RestoreDefaults
resets a column to. The nineteen overridable properties themselves start
with no override (AssignedValues
empty), so a freshly created column follows the grid live until one of
them is set explicitly.
Also creates this column’s own SubTitleFont
- a genuinely owned TFont, unlike Title.Font
which belongs to the native TColumnTitle - freed by a
matching Destroy override when the column itself is
destroyed.
