Solved InventoryClickEvent - Shift-Click place action?

I am trying to stop players from shift-clicking an item and move it inside a chest. I tried "event.isShiftClick()", however, players should be able to shift-click and move an item outside the chest. Is there anyway to do it?

Oh I knew how to do it now. Just use (event.getAction == InventoryAction.MOVE_TO_OTHER_INVENTORY && evnet.getRawSlot() != event.getSlot())
