in reply to WxPerl Next button

Refer to More wxPerl Examples now on Github. Specifically the CppTrial-pg086.pl and CppTrial-pg225.pl examples.

You may need to create a custom dialog similar to pg225 that uses radio buttons rather than a list box. Look these examples over and post your code if you can.

    Hi James, Thanks for your reply. I did use few of the examples from the github (very useful and thanks for sharing it). Here is the code: (input is at the end of the file) 
    use strict; 
use warnings; 
use Wx;
use Wx::Event qw( EVT_BUTTON );
use Wx qw[:everything];
use base qw/Wx::Frame/; # Inherit from Wx::Frame
our %panel;
my $selectedChapter;
Main( @ARGV );
exit( 0 );

sub Main {
    my $app = Wx::SimpleApp->new;
    my $frame   = Wx::Frame->new( undef, -1,  
                "Test window", [ 100, 100 ], 
                [ 800, 600 ], 
                Wx::wxDEFAULT_FRAME_STYLE()|Wx::wxTAB_TRAVERSAL() );

    MakeChaptersPanel( $frame );
    
    $frame->SetSizer( Wx::BoxSizer->new( Wx::wxVERTICAL() ) );
    $frame->GetSizer->Add( $panel{first},   1, Wx::wxEXPAND() );

    $frame->Show(1);
    $app->SetTopWindow($frame);
    $app->MainLoop;
} ## end sub Main

sub MakeChaptersPanel {
    my( $frame ) = @_;
    $panel{'first'} = Wx::Panel->new( $frame, -1, [ -1, -1 ],

      I second the use of Wx::SingleChoiceDialog or Wx::MultiChoiceDialog like jmlynesjr sugested.

      Parsing XML like you do is not a good choice, use a dedicated module, something like this:

      use strict;
use warnings;

use XML::Simple;
use Data::Printer;

my $data = do { local $/; <DATA> };          # slurp DATA

my $ref = XMLin(
    $data,
    #KeyAttr    => { Question => 'questionId' }, # unordered data
    ForceArray => ['item'],
    ContentKey => '-content'
);

p $ref;

      Notice that a valid XML must have a root tag. I also changed a little the structure...
