TCoolBands.Update procedure
Updates the specified item in the collection, and updates the cool bar when needed.
Declaration
procedure Update(aItem: TCollectionItem); overrideArguments
aItem | Collection item updated in the collection. |
Description
Update is an overridden method in
TCoolBands. It calls
the inherited method on entry to notify observers that the collection item
has changed. If a TCoolBar instance was assigned as the owner for the
collection, its CalculateAndAlign method is called to layout and resize the
visible bands for the control. The cool bar control is redrawn prior to
exiting from the method.
An experiment, built from development snapshots. Not the official Free Pascal or Lazarus documentation.
