I did this:
TComPortReadThread=class(TThread)
private
FBuffer: TBytes;
FReadPacketSize: integer;
FReadTimeout: integer;
public
MustDie: boolean;
Owner: TFpSerialPort;
constructor Create; override; //<= THIS ADDED, GIVES ERROR
property ReadPacketSize: integer read FReadPacketSize write
FReadPacketSize; //How many bytes to read in each operation
property ReadTimeout: integer read FReadTimeout write
FReadTimeout; //Max time to wait for data in thread
protected
procedure CallEvent;
procedure Execute; override;
published
property Terminated;
end;
and the code will not compile:
fpserialport.pas(41,17) Error: There is no method in an ancestor class
to be overridden: "constructor Create;"
So, does TThread not have a constructor????
I thought all objects had.
