  1. Best Answer

    The unit System.pas(which is automatically used by any Delphi unit) has the following definition:

    const
  sLineBreak = {$IFDEF POSIX} _AnsiStr(#10) {$ENDIF}
      {$IFDEF MSWINDOWS} _AnsiStr(#13#10) {$ENDIF};

    The code is taken from Delphi 10.2 Rio, but there is an equivalent mapping in all versions starting with Delphi 6 (approximately).

    Using this constant ensures that the correct line break will be added for the platform the executable is compiled on.

    So, to make a TLabelhave two lines, make sure it has the AutoSizeen property True, and then use code similar to the following:

    Label1.Caption := 'Hola' + sLineBreak + 'Mundo';

  2. Simply in the middle of the sentence a char(13) is added:

    Example :

    Label1.Caption := 'Hola' + char(13)+ 'Mundo';

    hello
    world
