@edvin uploaded a file:

I also pushed a new snapshot to sonatype so you can play with it now.

I forgot, is there a way to assign a variable in a builder ?

like:

vbox {
    var textbox = textbox("this is test") {}
}

@pike that's good for use within the vbox builder. if you want to use it in the class, make textbox the following var textbox : TextField by singleAssign() vbox { textbox = textbox("this is a test") {}

}

thanks, I remembered reading it somewhere with the single assign

textbox is your own class?

no, I was just writing pseudoCode...

ok

I want to figure out how to make my hover chart like a builder so I can update it when the observable list changes.

probably since I have it like this: class HoverChart(title: String, val dataSeries: ObservableList<DailySalesModel>): StackPane() {} on the init {} I can just add a listener to the dataSeries object right?

@pike That sounds good. Before you assign a UI element to a field in your class, consider creating a property and binding towards that instead. More often than not you'll see that it avoids the UI element reference and also cleans up your code in terms of semantics.

yeah, I've noticed that a lot more, make an observable, put it somewhere in the ui, update the model

makes the view really dumb and easy to play with

@pike Yeah, I really like this pattern myself. It feels more solid, and you're adjusting parameters with a little more semantic value IMO.

@edvin https://cl.ly/2W053C1p2X0Z I implemented this view, I created a tree table view. And passed empty strings to column fields like this

Liabilities("Capital Account", "", "12121212.00",
                        listOf(
                                Liabilities("Sandeep Kumar", "123561", "")
                        )))

class Liabilities(
        val particulars: String,
        val amount1: String,
        val amount2: String,
        val voucherList: List<Liabilities>? = emptyList())

And populated the data in TreeTableView. Is this the correct way?

@ajithprasaad I think you only pasted your data, not the builder code that generates the TreeTableView.

init {
Liabilities("Capital Account", "", "12121212.00",
                        listOf(
                                Liabilities("Sandeep Kumar", "123561", "")
                        )))
}

treetableview<Liabilities> {
                        style {
                            backgroundColor += c("#dffeff")
                        }

                        addClass("tree-table-hidden-header")

                        column("", Liabilities::particulars)
                        column("", Liabilities::amount1)
                        column("", Liabilities::amount2)

                        isShowRoot = false

                        root = TreeItem(Liabilities("", "",
                                "", liabilities))

                        populate { it.value.voucherList }

                        root.isExpanded = true
                        root.children.forEach { it.isExpanded = true }

                        columnResizePolicy = TreeTableView.CONSTRAINED_RESIZE_POLICY

                    }


class Liabilities(
        val particulars: String,
        val amount1: String,
        val amount2: String,
        val voucherList: List<Liabilities>? = emptyList())

@ajithprasaad That looks good! 👍

@edvin, how Can I set number of rows in tableview via code?

@edvin https://cl.ly/2W053C1p2X0Z but I'm trying to insert a table in one of the rows of tree table view like in this picture.

@anujkrvaish What do you mean by "set the number of rows"?

I want to limit the number of rows in tableview to 1.

@ajithprasaad You can revert to TableView and use the TableView Row Expander perhaps 🙂

@anujkrvaish Just limit the items in the list you connect to the tableview 🙂

If you only have a single row I don't think TableView makes much sense though.

I passed only 1 item to the table but it is taking extra space available and showing empty rows

@anujkrvaish You have to manually determine the height of your TableView. TableView doesn't return a preferred size based on it's rows.

Actually I want to show total field in a treetableview at the last row, so I came up with this "HACK"
