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

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...

Regards, Stefan

After reviewing and running your code, and having read a zillion of theses posts now, I knew that a more learned Monk would suggest using one of the CPAN XML parsers. Thanks stefbz. I have not gotten into XML at all yet.

I do think that you should be using a dialog(modal) rather than individual controls. I would start with the wxSingleChoiceDialog and use it to get my application logic correct. Build and popup the dialog, extract your answer, destroy the popup, then repeat for all of your questions. Then if you still want a different look and feel you could implement a custom dialog like the wxSingleChoiceDialog, but using radio boxes instead of a list. See CppTrial-pg225.pl for the wxSingleChoiceDialog example and CppTrial-pg245.pl for the PersonalRecordDialog custom dialog example.

The next more complicated option would be to create a wxWizard. Unfortunately I haven't yet implemented the wxWizard example from the "wxBook" in my github examples.

See also the wxDemo wxWizard and wxSingleChoiceDialog examples. I run Citrus Perl 5.16 and on my system these can be found at home/CitrusPerl/perl/vendor/bin/wxperl_demo.pl. Look under the Managed Windows and Dialogs sections.

Please repost your working application to add to the example base.

Update1:See if the following code can be integrated with your XML code.

Update2:Just for completeness a wxWizard example follows.

Hi James/Stefan, Thanks for the valuable input. Since I have to print line-by-line as we select the correct answer (this app is just to verify the correct answers), I chose not to use XML parsers since anytime the actual XML file several additional nodes that I don't need in (both inside and outside the question node). I have made some good progress by destroying and recreating RadioBox when the user selects next button. After testing the code thoroughly, I will post it and you can modify (if required) and add it to the examples. Regards Saran
