Perl/Tk saves your favourite tools

• There is also a class Dialog, but this is just meant as example.
• Because of the OO structure, you have local names for objects, instead of the global object paths of Tcl.
• we may also write

     $d = Toplevel $mw -class => 'Dialog';
     title $d 'example';
     ...
  

  This list-notation syntax of OO-Perl looks similar to the Tcl program, however list-notation does not provide stacking of calls. Your programs will be more verbose and need more variables in that notation.
• Naming of components is not required, which saves you from looking for explanatory names for simple components in most cases.
• MainWindow can be used in Perl/Tk on every spot where Tcl requires Toplevel: the MainWindow is a more flexible object. On UNIX you can have more than one under control in one program.
