Hello monks,

Is it possible to select just one check button in Tk? I have two buttons, and I want to have the second one return to a normal state if the other is selected.

This is what I have for code 

my $snmp_version1 = $right_frame->Checkbutton(
        -text         => 'SNMPv1',
    -indicatoron => 'false',
    -selectcolor => 'green',
    -command     => sub {$version = 1;},
    );
    $snmp_version1->pack(-padx => 5, -pady => 5,-anchor => 'w');
    &BIND_MESSAGE($snmp_version1, "Send SNMP version 1 Traps");
    
    my $snmp_version2 = $right_frame->Checkbutton(
    -text         => 'SNMPv2',
    -indicatoron => 'false',
    -selectcolor => 'green',
    -command     => sub {$version = 2;
                 $snmp_version1->{'normal'}},
    );
    $snmp_version2->pack(-padx => 5, -pady => 5,-anchor => 'w');
    &BIND_MESSAGE($snmp_version2, "Send SNMP version 2 Traps");

Any ideas why this won't work?

Thanks
