Thanks alot. This has worked really well except for one small problem.
Instead of using the tree to recieve the received command I've set it up
so tree items can receive this signal. However only the root TreeItem
actually works all the others seem not to at all. I'm using the same
code to do both, is there a particular order in which this must be done?
Or can you only set this up before the window is displayed?

Here is what I do in my expand routine, that should add the recieve
method to all my TreeItems.

$newItem = new_with_label Gtk::TreeItem($value);
$subTree->append($newItem);
$newItem->signal_connect('select', \&treeItemSelected, $value);
$newItem->signal_connect('button_press_event', \&treeButtonPressed);
$newItem->drag_dest_set('all', ['copy', 'move'],
        {target=>'STRING', flags=>0, info=>0});
$newItem->signal_connect('drag_data_received', \&recieveDragData);
$newItem->set_user_data($value);
$newItem->show();

This exact same code works to setup the initial root TreeItem.
