title: How do I clear a Frame's value in Perl/Tk?
body: <p>In Perl/Tk I have designed one interface in that I have  one frame. 
  That frame has an Entry and Text box. When I am clicking the button 
  those Entry and Text value has to clear in the Frame. I know that I can 
  access each object then I can clear using delete function. 
  I need to do as like HTML form reset button functionality. How can I do these things in Perl Tk?</p>
