[1.7.2] Event for block placing?

[rustyminer28]

I'm making an item that protects any BlockContainer or subclass of from intruders and I need an event to handle block placing, so I can get the original placer. Is there any method for checking this on items or an event for it? I though about PlayerInteractEvent, but it would register every time someone opens the chest. And I only want it to allow chests placed AFTER mod installation.

/**

     * If a Block Place event is cancelled, the block will not be placed.
     */
    @Cancelable
    public static class PlaceEvent extends BlockEvent

     */
    @Cancelable
    public static class PlaceEvent extends BlockEvent

That was added in 1.8.

EDIT: 1.7.10.

I have it in my 1.7.10 workspace...

 

@OP, update to 1.7.10. No need to use 1.7.2.
