Disabling taking items from chests.

How can I make it so when a Player takes a item from a chest it puts the item back, so they can't take the items in a chest, but still view the chest.

 

Inventory click event, event.getInventory().getHolder(), and event.setCancelled()

 

Can anyone write something for me, I really am stuck.

 

I am writing a huge plugin called Deposit Chest. I will gie you some basic source in a bit.

 

If you could send me some or post it here that would be so awesome.
Thankyou

 

My actual event is over 100 lines, so I am going to give you a short version. Tell me if you need more help.

Code:java

 
@EventHandler
public void onInventoryClick(InventoryClickEvent event) {
if(!(event.getWhoClicked() instanceof Player)) return; //Make sure it was a player.
if(event.getSlotType() != SlotType.CONTAINER) return; //Make sure it is the chest's inventory.
if(event.getInventory().getType() != InventoryType.CHEST) return; //Make sure it was a chest.
Player p = (Player) event.getWhoClicked(); //Get the player who clicked on the block.
if(event.getInventory().getItem(event.getSlot()) != null) { //Check if it was a withdrawal.
//Withdrawal
InventoryHolder ih = event.getInventory().getHolder();
if(ih instanceof Chest) {
Chest eventChest = (Chest) ih;
Location chestLoc = eventChest.getLocation();
 
}
else if(ih instanceof DoubleChest) {
DoubleChest eventChest = (DoubleChest) ih;
Location chestLoc = eventChest.getLocation();
}
}
else {
//Deposited...
}
}
