Yes, if you don't use a subclass of scope to put data in it, that's the easiest way to declare a new scope.

What closes out a scope?

@carlw

deregister()

?

when the Modal is closed?

not sure... the function is on the Scope class...

@User uploaded a file: Untitled

It's called on the default scope when the application is stopped...

In the SO example, I could have called

scope.deregister()

from the

onUndock

, but the scope would be garbage collected either way when there are no more references to the fragment.

Off topic maybe... https://spring.io/blog/2017/01/04/introducing-kotlin-support-in-spring-framework-5-0

Nice to see them taking Kotlin seriously K

@ron In your blog post you said that the fragments were not added to the views, but that was not the case. It was added, everything Node related was working, but since it was instantiated manually the fragment was never registered as docked, so it didn't receive events.

I will update it

How do I add persistent DB to a tornadoFX app?

I saw @thomasnield s example project, but the DB is not persistent it's in memory

@edvin like this : During a nice talk in the tornadoFX slack channel one of the members noticed that his Fragments were being added to the view he was working on, but they dot not receive any event(like onDock). The reason was that he manually instantiated the fragments:

@nakamin With sqlite, it's just a matter of changing where the database is stored.

DriverManager.getConnection("jdbc:sqlite::memory:")

:memory:

is a keyword for creating an in memory database. Change it to the filename of the database if you want it persisted:

DriverManager.getConnection("jdbc:sqlite:storage.db")

But if I package the app as a self executable jar, will the file still be accessible?

And where would it be stored?

you can store it as a resource

but then it will be a readonly database I guess 😉

Yeah, exactly, and that would be useless in my case

Just use an absolute path to the database if you want to create and use one on disk.

I would recomend the

user.home

preference if you only need one database for the app.

@Ruckus yeah, that's what I saw in most stack overflow answers. I guess

user.home

it is. Thanks 😁

No problem 🙂

I usually use

user.home

for app configuration, and let the user choose the location for any "project" specific data.

@ron That's perfect 🙂
