I have complicated TK window. The data and buttons in the window relate to a variable $product that can take one of several values. The window has many widgets: menus, labels, option buttons, entry forms, etc. All of these widgets depend on the currently selected $product.

The user can select a product to work on from a top menu in the window.

Currently, I am doing something brutish to rebuild the window when the user selects a new product to work on: 

# note: $TOP is a global, the MainWindow

sub create_screen {
  $TOP->destroy if $TOP; # brutish!
  $TOP = MainWindow->new( title => 'product' );
  $TOP->optionAdd( "*tearOff", "false" );
  ... etc ...

Destroying the whole window seems a very crude way to refresh it. It also causes a noticable blink of almost a second.

What's the polite way to redraw the screen, if some of the widgets weren't/can't be tied with $textvariable, etc?

Thanks, gang, for all the TK advice and help.

It is very much appreciated --
