CraftItemEvent, InventoryCreativeEvent

public class InventoryClickEvent
extends InventoryInteractEvent

This event is called when a player clicks a slot in an inventory.

Because InventoryClickEvent occurs within a modification of the Inventory, not all Inventory related methods are safe to use.

The following should never be invoked by an EventHandler for InventoryClickEvent using the HumanEntity or InventoryView associated with this event:

• HumanEntity.closeInventory()
• HumanEntity.openInventory(Inventory)
• HumanEntity.openWorkbench(Location, boolean)
• HumanEntity.openEnchanting(Location, boolean)
• InventoryView.close()

To invoke one of these methods, schedule a task using BukkitScheduler.runTask(Plugin, Runnable), which will run the task on the next tick. Also be aware that this is not an exhaustive list, and other methods could potentially create issues as well.

Assuming the EntityHuman associated with this event is an instance of a Player, manipulating the MaxStackSize or contents of an Inventory will require an Invocation of Player.updateInventory().

Modifications to slots that are modified by the results of this InventoryClickEvent can be overwritten. To change these slots, this event should be cancelled and all desired changes to the inventory applied. Alternatively, scheduling a task using BukkitScheduler.runTask( Plugin, Runnable), which would execute the task on the next tick, would work as well.

Modifier and Type	Method	Description
@NotNull InventoryAction	getAction()	Gets the InventoryAction that triggered this event.

@Nullable ItemStack	getCursor()	Gets the current ItemStack on the cursor.

@NotNull HandlerList	getHandlers()
int	getHotbarButton()	If the ClickType is NUMBER_KEY, this method will return the index of the pressed key (0-8).
int	getRawSlot()	The raw slot number clicked, ready for passing to #getItem(int) This slot number is unique for the view.
int	getSlot()	The slot number that was clicked, ready for passing to Inventory.getItem(int).
@NotNull InventoryType.SlotType	getSlotType()	Gets the type of slot that was clicked.
boolean	isLeftClick()	Gets whether or not the ClickType for this event represents a left click.
boolean	isRightClick()	Gets whether or not the ClickType for this event represents a right click.
boolean	isShiftClick()	Gets whether the ClickType for this event indicates that the key was pressed down when the click was made.
void	setCurrentItem(@Nullable ItemStack stack)	Sets the ItemStack currently in the clicked slot.
void	setCursor(@Nullable ItemStack stack)	Deprecated. This changes the ItemStack in their hand before any calculations are applied to the Inventory, which has a tendency to create inconsistencies between the Player and the server, and to make unexpected changes in the behavior of the clicked Inventory.
