Getting confused on how to layout logic inside the above ListCellFragment, for example if I wanted to add a label based on the students age what is the correct way to do that? i.e. if (student.age > 21) label("This student can drink alcohol")

Am I supposed to be adding a change listener onto age and updating the label text based on that?

@elaborate tissue you just need to use the itemview model and a cell formater

pike

Copy code

tableview(persons) {
    column("Age", Person::Age). cellFormat {
      text = if(it > 21) "This student can drink alcohol" else "They can't"
  }
}

@edvin I could copy some of my authy login into a splash app, I basically do the same thing, but instead of a splash screen it's an auth screen (and there's a crazy background polling section)

@pike We have a login example, and I want to keep these as simple as possible. Maybe you could use the code I posted and combine with your polling stuff?

pike

yeah, I was saying I could write out a splash app sample

pike

I used FX.primaryStage.scene.root to "swap" from the login to the main view.

pike

02/27/2018, 12:06 PM

modal wasn't working "nicely" for authy login.

pike

02/27/2018, 12:16 PM

Anyway, made a splash loading screen with an incremental progressbar as a sample... now to style it

pike

02/27/2018, 12:21 PM

So, I just clone samples, and add a module to it then try for a PR ?

pike

02/27/2018, 1:22 PM

no idea how to add it 😛

@mariofelesdossantosjr I wouldn't edit a list in a table column.

I am not great with coroutines so I might be doing something wrong. Basically all I want is to run a method that does something on the ui thread after a specific delay:

Copy code

runAsync {
    Thread.sleep(1000)
} ui {
    doSomething()
}

this does not seem to be working correctly

@mariofelesdossantosjr you should create some kind of form with a list of all customers a vendor has and actions associated with managing the customers. such as update or delete. The update function would then send you to a customer edit view. Once you persist the changes to the database, you can go back to the vendor table view and refresh the observable list of vendors by fetching the vendors again.

@mariofelesdossantosjr actually you can use the

TreeTableView

. I haven't used it but there are examples in the docs. But I usually approach the work flow as described above.

The tableview example is broken, unless I am missing something

Copy code

class HelloWorld : View() {
    val rows = listOf(
        Row("key", "value"),
        Row("test", "two")
    ).observable()

    override val root = vbox {
        tableview(rows) {
            column("Field", Row::key)
            column("Value", Row::value)
            columnResizePolicy = SmartResize.POLICY
        }
    }
}

Fails with

Row

being defined as

data class Row(val key: String, val value: String)

The fix if anyone is interested is to use

readonlyColumn

instead.

What are the uses for observable list? I would like to bind a list of text fields to an observable list of values. So something like a list view but with text fields.
