TCustomIcon.ReadData procedure
Reads data for the class instance from a stream.
Declaration
procedure ReadData(Stream: TStream); overrideDescription
ReadData is an overridden method used to read the data for the
class instance from the TStream instance specified in
Stream.
ReadData is the method called when TFiler reads a persistent object during
LCL component streaming.
ReadData saves the position in Stream on entry, and restores the original position prior to exiting from the method.
ReadData checks the values in Stream to determine if a size prefix for the
content is stored in the stream. Delphi streaming does not include the size
prefix. Current Lazarus versions do. When the LongInt value used
as the StreamSignature is 0, the LoadFromStream method is called to load the
contents of the stream. Otherwise, the inherited method is called to complete
the operation.
ReadData is also called from the LoadFromResourceHandle method in
TIcon.
