Combo and ClientData (was: RE: Help with Wx::Perl::PubSub)

Hi there,

Steve, Thanks for the example and the urls. I'm on W7 and I didn't want to install Python + wxPython, so I'm using wxFormBuilder to produce xrc files that I load with perl.

Using an array (or an hash with id/position in the combo) that shadows the combox content works, but I would like to associate the id with combo using client data. 

In my code

$w holds a Wx::ComboBox ref.
If I loop through the id and the names I want to show in the combo:

  $w->Append($displayedValue); # string for position $i
  $w->SetClientData($i, $value); #$value is what I want retrieve from the selection

But 

Print Dumper $w->GetClientData($i)); return undef

What am I missing ? Is there some lines of working code somewhere ?

Thanks

François
