fix GdkEvent, GdkEventButton, GdkEventKey properties initiation #106

[d47081]

Solution for GDK warnings (#106)

can you provide a simple code with the problem?

This issue happens on:

• keypress on entry
• button click event

Common GdkEvent (that implements GdkEventButton, GdkEventKey) also drop warnings for type, key, button.

This solution resolve the problem using nullable properties initiation on __construct. Resulting event dump in testing application looks well (as designed)

        $entry->connect(
            'key-release-event',
            function (
                \GtkEntry $entry,
                \GdkEvent $event
            ) {
                var_dump($event);
            }
        );
