Trying to trigger wxEVT_TREELIST_ITEM_CHECKED programmatically: not implemented?

[Helen Craigman]

Hi wxPerl-users

I am using wxPerl with wxWidgets 2.9.5. I am using TreeListCtrl, and need
 to implement triggering EVT_COMMAND_TREELIST_ITEM_CHECKED
 programmatically.
 
Here is a code excerpt:
------------------------

# ...
use Wx qw( :treectrl :listctrl wxDefaultPosition wxDefaultSize
# ...
         wxEVT_TREELIST_ITEM_CHECKED);
# ...
my $tree = Wx::TreeListCtrl->new( $panel_tree, -1, wxDefaultPosition,
            [400,200], wxTL_CHECKBOX|wxTL_MULTIPLE);
# ...

# Create an EVT_COMMAND_TREELIST_ITEM_CHECKED artificially, and
# trigger it
 my $evt = Wx::CommandEvent->new(wxEVT_COMMAND_TREELIST_ITEM_CHECKED,
      $tree->GetId);
   $evt->SetEventObject($tree);
   $evt->SetId($tree->GetId);
   $tree->GetEventHandler->ProcessEvent($evt);
# ...
---------------------------

For either wxEVT_TREELIST_ITEM_CHECKED or
 wxEVT_COMMAND_TREELIST_ITEM_CHECKED, compilation fails with the error:
 
------------
"wxEVT_TREELIST_ITEM_CHECKED" is not exported by the Wx module
------------
Your advice will be appreciated.
Many TIA - Helen
