TListColumn.Assign procedure
Copies properties from the specified persistent object to the current class instance.
Declaration
procedure Assign(ASource: TPersistent); overrideArguments
ASource | Persistent object with values copied in the method. |
Description
Assign is an overridden method used to implement object
persistence for the
TListColumn type. It copies property values
from the persistent object in
ASource into the current class
instance. When ASource is derived from TListColumn, the following properties
are copied:
- Alignment
- AutoSize
- Caption
- MaxWidth
- MinWidth
- Visible
- Width
The Changed method is called to signal a change in the values for the collection item.
If ASource is not derived from TListColumn, the inherited method is called using ASource as an argument. An EConvertError exception is raised if ASource has not been assigned (contains Nil).
