Oh thanks, but don't think that I am as good as you in Wx. I am a real beginner with this GUI yet.
BTW, I discovered that we can create a CHM viewer using WxPerl with a few lines of code, and it is as accessible as MS HTML Help viewer.
I haven't discovered yet how to find the object of a control or menu if I know its ID though.

Subject: Another FruitBasket with Wx

Hi,

I've made another FruitBasket made with Wx in perl. I've seen that the
syntax of WxPerl is not so nice as the syntax of Win32::GUI, but I thought 
that the source code should be smaller, because it doesn't use that
hash-style of providing parameters to functions.

Finally I've made a Fruit Basket with WxPerl that has only around 750
characters, and it is still pretty clear. The version below has 950
characters because it has some more spaces.

It might be helpful for those who want to learn WxPerl, especially that
there is so little documentation for WxPerl.
(I've created an executable program and I put it and the source code, and a 
version with some explanations at:
http://www.tranzactiibursiere.ro/static/FruitBasket_Wx.rar

Here it is:

use strict;
use Wx qw(wxALIGN_RIGHT);
use Wx::Event qw(EVT_BUTTON);

my $frame = Wx::Frame->new(undef, -1, "The app", [-1,-1], [200,150]);

my $panel = Wx::Panel->new($frame, -1);
Wx::StaticText->new($panel, -1, "&Fruit:", [20,20], [30,20], wxALIGN_RIGHT); 

my $fruit = Wx::TextCtrl->new($panel, -1, "", [50,20], [100,20]);

my $add = Wx::Button->new($panel, -1, "&Add", [150,20], [50,20]);

$add->SetDefault;

Wx::StaticText->new($panel, -1, "F&ruits:", [20,60], [30,20],
wxALIGN_RIGHT);

my $list = Wx::ListBox->new($panel, -1, [50,60], [100,100]);

my $del = Wx::Button->new($panel, -1, "&Delete", [150,60], [50,20]);

EVT_BUTTON($frame, $add, \&add);
EVT_BUTTON($frame, $del, \&del);

$frame->Show(1);
Wx::SimpleApp->new->MainLoop;

sub add {
my $current_fruit = $fruit->GetValue;

if (defined $current_fruit) {
$list->Append($current_fruit);
$fruit->Clear;
}
}

sub del {
my $index = $list->GetSelection;
$list->Delete($index) if $index >= 0;
}
