the following would have to be run

sudo apt-get install openjfx

this is for people who are working with native for the first time. Then it has to be reimported into the jdk

@amanda.hinchman-dominguez That's right for OpenJDK. JavaFX has never being bundled with OpenJDK (It has only been bundled with Oracle JDK) So if you have OpenJDK running, you need to install OpenJFX along with it and it goes for all platforms (Win, Mac, Linux)

@amanda.hinchman-dominguez if you wanted an easy-to-install (at least on ubuntu) Oracle Linux JDK: https://launchpad.net/~webupd8team/+archive/ubuntu/java

Hey. Could anybody give me a hint how to create a tableview with readonlyColumn for a plain old java object? I want to call a getter. Somehow I have to wrap it into a ObservableValue. Is there a nice way to do it? The value will never change since the java object is immutable. Any way to call "toProperty()" or something like that?

I just want to add a lambda that will return a value (or a value wrapped in an observable type)

@jschneider Can you provide a runnable example? AFAIK, POJO should run fine with TableView. TableView will just not respond to any changes made to its data.

The problem is, I can not figure it out. It does not compile for me. But I have a minimal example that should make it clear:

Here it comes:

class RoDemo: View("asdf"){
  override val root: Parent = borderpane{
    val data = listOf(Instant.now()).observable()

    tableview(data) {
      readonlyColumn("Millis", Instant::toEpochMilli)
    }
  }
}

I think you should get the idea

@carlw Demo compiles with

column

. Check this:

import tornadofx.*
import java.time.Instant

class RoDemo: View("asdf"){
    override val root = borderpane {
        val data = listOf(Instant.now()).observable()

        tableview(data) {
            column("Millis", Instant::toEpochMilli)
        }
    }
}

which makes me wonder why does it not compile with

readonlyColumn

?

@jschneider i think you should access that through a field instead of a function

Ok, I get it.

readonlyColumn

expects a property 😄

But how can I access through a field?

Ok. it works with column. So far so good. Thanks

@abhinay that compiles, but doesn't display anything. you need to provide column with some meta information like this in plain javafx

tcId.setCellValueFactory(new PropertyValueFactory<MyObject,Number>("id"));

that's the gist of what column{} is doing

Sure. I was just trying to compile things.

@abhinay does your example compile for readonlyColumn or just column?

it only compiles for column

Just column because it accepts a function which

Instant::toEpochMilli

exactly is..

does your program display anything in the column?

@jschneider IMO, the right way to start with TableView samples is always to start with a Model as @carlw has shown.

I didn't run it 😇

In the real world one does not always have a Kotlin model. I have plain java objects here. Unfortunately

i think that function version is lacking the meta information to configure the column

It doesn't need a Kotlin or JavaFX model

Plain Java objects should work

Instant.toEpochMillis is a function. I think you'd have better luck with a POJO long field
