Have you looked at $widget->hide() as a solution. I reckon that if you 
build a dialog with 9 input boxes with predictable names you can then do

  $window->FORM->{"text$i"}->hide;
  $i++;

in a loop in the signal handler that constructs or raises the dialog. If
you are reusing the dialog you may need to call 

  $window->FORM->{"text$i"}->show;

to make them visible again.

You will also notice that the sub is called frig_Gnome_Dialog_buttons() :)
and was added because there was a mismatch between the way that Glade
stores the buttons/labels and the way that Gnome constructs them. You can
not access the buttons until they are automagically constructed so to add
accelerators and connect signals you need two passes through the Glade
widget structure or do it the way that Glade-Perl does it.

I will have another look at it to see if I can make it simpler or if
Gtk-Perl has some newer methods to achieve the same thing. Thanks for
pointing it out.

I hope that I am nearer this time. Please let me know how you get on - it
is a great help to me to know what people are really developing.
