Solved Set inventory slot for specific item only?

[Zyxed]

Hello!
Is it possible to set slot in player's inventory to only one item? For an example:
Slot 9 of player's inventory is locked, and you can't put any items in it, except stone. So the slot would be locked for every other item than stone. I've been trying to figure this out for hours. Can anyone help me with this?

Inventory click event, there is a way to get the cursor item but not sure how the syntax was

on inventory click:
    if name of event-inventory is "test":
        if index of event-slot = 0:

Thanks for the answers! I got it working like this (I think it could be better, but it's fine for me)

on inventory click:
    if event-inventory = Player's inventory:
        if event-slot = 9:
            #Nopeuden sormus
            if player's cursor slot is not saddle or air: #Antaa asettaa slot 9 vain satulalle, ja ottaa sen pois.
                cancel event
            if event-slot is saddle named "&aNopeuden sormus" with lore "&7Nostaa pelaajan nopeutta 20%%": #Poistaa efektin
                remove speed from the player
            if player's cursor slot is saddle named "&aNopeuden sormus" with lore "&7Nostaa pelaajan nopeutta 20%%":
                apply potion of Swiftness to player for 10000000 seconds #antaa efektin
