I played around with your example and came up with the following. You
don't have to manually insert the characters and the filter works even
though the logic of the if() statement may seem "backwards." Other than
that, it's pretty straightforward, IMHO.
Hope this helps.
<?php
function onInsert($widget, $event)
{
$result = false;
$character = chr($event->keyval);
if(!preg_match("/[0-9a-fA-F]/", $character))
{
$result = true;
}
return($result);
} // onInsert()
$entry = new GtkEntry();
$entry->connect('key-press-event', 'onInsert');
$window = new GtkWindow();
$window->set_size_request(400, 200);
$window->connect_simple('destroy', array('Gtk','main_quit'));
$window->connect('destroy', array('Gtk','main_quit'));
$window->add($entry);
$window->show_all();
Gtk::main();
?>
