Who has examples of using cell value factory and cell factory on TableColumn?

[Alain FAGOT BÉAREZ]

Dear all,

In order to close the issue 10 (http://code.google.com/p/scalafx/issues/detail?id=10) before the end of our series of milestones, I would like to add some tests, or at least little demos, for the use of CellValueFactory and CellFactory with TableColumn.

From my current application, I will extract the code for CellFactory with ComboBox, which is kind of a different beast.

Thanks for your contributions,

Alain

What about an editable table with checkboxes, etc in the TableCell's.
See my question on stackoverflow: http://stackoverflow.com/questions/18207446/editable-boolean-columns-in-scalafx-tableview.

There are some examples in https://github.com/jsacha/ProScalaFX/blob/master/src/proscalafx/ch05/ui/StarterAppMain.scala , partially illustrating difficulty with using CellValueFactory from ScalaFX.

Here is an example of an editable check box used together with BooleanProperty:

import scalafx.Includes._

import scalafx.application.JFXApp

import scalafx.application.JFXApp.PrimaryStage

import scalafx.beans.property.{BooleanProperty, StringProperty}

import scalafx.collections.ObservableBuffer

import scalafx.scene.Scene

import scalafx.scene.control.TableColumn._

import scalafx.scene.control.cell.{CheckBoxTableCell, TextFieldTableCell}

import scalafx.scene.control.{TableColumn, TableView}

object SimpleEditableTableView extends JFXApp {

  class Person(firstName_ : String, age_ : Int, cool_ : java.lang.Boolean) {

    val name = new StringProperty(this, "Name", firstName_)

    val cool = new BooleanProperty(this, "Cool", cool_)

  }

  val characters = ObservableBuffer[Person](

    new Person("Peggy", 45, false),

    new Person("Rocky", 43, true)

  )

  // Print changes

  characters.zipWithIndex.foreach {

    case (c, i) => c.cool.onChange((_, oldValue, newValue) => println(i + " changed from " + oldValue + " to " + newValue))

  }

  val coolColumn = new TableColumn[Person, java.lang.Boolean] {

      text = "Cool"

      cellValueFactory = _.value.cool.delegate

      prefWidth = 180

  }

  coolColumn.setCellFactory(CheckBoxTableCell.forTableColumn(coolColumn))

  stage = new PrimaryStage {

    title = "Simple Table View"

    scene = new Scene {

      content = new TableView[Person](characters) {

        editable = true

        columns ++= List(

          new TableColumn[Person, String] {

            text = "First Name"

            cellValueFactory = _.value.name

            prefWidth = 180

          },

          coolColumn

        )

      }

    }

  }

}

Thanks, that did the trick for me. I tried using java.lang.Boolean before, but got stuck on an error in the line `cellValueFactory = {_.value.cool}`. In retrospect it's now obvious I should've used `_.value.cool.delegate`, not `_value.cool`.
