TListColumns.Update procedure
Checks whether the collection update is actually need and calls the inherited method.
Declaration
procedure Update(Item: TCollectionItem); overrideArguments
Item | Collection item (TListColumn) updated in the method, or Nil. |
Description
Update is an overridden method in
TListColumns. It
checks whether the update is actually needed for the collection when the
value in Item is
Nil. If the collection update is required, Item is
set to the internal collection item that has been cached for the action. This
occurs when the collection calls its Changed method with its AllItems
argument set to
True.
Update calls the inherited method using the value in Item as an argument.
