Description

An error message.

The error class represents an error message. It provides a uniform interface for error reporting and handling via the Object Pascal exception mechanism. Error exceptions may be caught and recovered from:

try
  { open the console at 640x480 resolution }
  console.Open('Error example', 640, 480);
except
  on error: TPTCError do
  begin
    { fallback to default resolution }
    console.Open('Error example');
  end;
end;

Or allowed to fall through to the main try/except block and get reported to the user:

try
  { open the console at 640x480 resolution }
  console.Open('Error example', 640, 480);
except
  on error: TPTCError do
  begin
    { report error }
    error.Report;
  end;
end;
