Re: Key Press php-gtk1

Not sure if messages are going through or not but...

I've discovered the key-press-event and key-release-event and while
key-press is working for me, the key-release does not seem to work.

Here is a snippet from my code:

$alert_window = &new GtkWindow(GTK_WINDOW_DIALOG);
$alert_window->connect('delete-event', 'hide_window');
$alert_window->set_border_width(0);
$alert_window->set_policy(0, 0, 0);
$alert_window->set_title('Notice!');
$alert_window->set_name('AlertWindow');
$alert_window->set_usize(400,430);
$alert_window->realize();
$alert_window->set_position(GTK_WIN_POS_CENTER);
$alert_window->connect('key-press-event', 'onKeyPress');
$alert_window->connect('key-release-event', 'onKeyRelease');
-----------------8<--SNIP

/***** ONKEYPRESS/RELEASE() *****/
function onKeyPress($widget, $event) {
  global $righthand, $lefthand;
  echo "Pressed: " . $event->keyval;
  return true;
}
function onKeyRelease($widget, $event) {
  global $righthand, $lefthand;
  echo "Released: " . $event->keyval;
  return true;
}

Key Press echo's Pressed and a value (numeric) but the key release
does nothing. Am I doing something wrong?
