( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Hi folks, i was asked to make a gui front end for my recent perl program. I chose perl/Tk which i'm totally new to. However, i was really impressed how quickly i was able to knock something up just by cutting and pasting a few examples i found on the web!

Anyway, the gist of my question is: If i have a couple of radio buttons, how do i set the gui so that part of it is greyed out or (preferably) disappears when one of the radio buttons is pressed?

I've tried searching through examples (there's a lot of good examples) but i can't find any which do this sort of thing! Apologies for the really long post. I hope it's clear. Thanks!

This is the full program/gui:

#!/usr/bin/perl -w

my $mw=new MainWindow;

I'd like when pressing the "Netlist" radio button at the top, for the "template" input fields do dissappear.

Then when pressing "Template" radibutton, the opposite, so only the "template" input fields would be present (and of course, the 2 buttons in both cases)

So the gui for the netlist radio button having been pressed would look like:

#!/usr/bin/perl -w
use strict;
use warnings;

use Tk;
# Main Window
my $mw=new MainWindow;
$mw->title("Analog Test Mux Generator");
# Framed Radio buttons at top to choose output

#--------------------------------------------
my $frame=$mw->LabFrame(
        -label=> "Ouput Select",
        -labelside=>'acrosstop',
        ) ->pack(-expand=> '1', -fill=>'both', -side=>'top');
$frame->Radiobutton(
    -variable=>\$output_select,
    -value=>'netlist',
    -text=>'Generate Netlist',
        ) ->pack(-side=>'left');
$frame->Radiobutton(

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":


  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
