TornadoFX - remove item with ContextMenu right click option - kotlin

Question

So I have a table view that displays an observedArrayList of AccountsAccount(name, login, pass), those are data classes. When I right click a cell there pops an option of delete. What I want to do is delete that Account from the observedArrayList
Only I can not find any way to do this. I am not experienced with JavaFX or TornadoFX and I also can't find the answer with google or in the TornadoFX guides and docs.
This is my code:
class ToolView : View() {
override val root = VBox()
companion object handler {
//val account1 = Account("Google", "martvdham#gmail.com", "kkk")
//val account2 = Account("Google", "martvdham#gmail.com", "Password")
var accounts = FXCollections.observableArrayList<Account>(
)
var gson = GsonBuilder().setPrettyPrinting().create()
val ggson = Gson()
fun writeData(){
FileWriter("accounts.json").use {
ggson.toJson(accounts, it)
}
}
fun readData(){
accounts.clear()
FileReader("accounts.json").use{
var account = gson.fromJson(it, Array<Account>::class.java)
if(account == null){return}
for(i in account){
accounts.add(i)
}
}
}
}
init {
readData()
borderpane {
center {
tableview<Account>{
items = accounts
column("Name", Account::name)
column("Login", Account::login)
column("Password", Account::password)
contextMenu = ContextMenu().apply{
menuitem("Delete"){
selectedItem?.apply{// HERE IS WHERE THE ITEM DELETE CODE SHOULD BE}
}
}
}
}
bottom{
button("Add account").setOnAction{
replaceWith(AddView::class, ViewTransition.SlideIn)
}
}
}
}
}
Thanks!

Answer 1

To clarify #Martacus's answer, in your case you only need to replace // HERE IS WHERE THE ITEM DELETE CODE SHOULD BE with accounts.remove(this) and you're in business.
You could also replace the line
selectedItem?.apply{ accounts.remove(this) }
with
selectedItem?.let{ accounts.remove(it) }
From my experience, let is more common than apply when you are just using a value instead of setting up a receiver.
Note that the process will be different if the accounts list is constructed asynchronously and copied in, which is the default behavior of asyncItems { accounts }.

Answer 2

selectedItem is the item you have selected/rightclicked.
Then you can use arraylist.remove(selectedItem)
