The Alert class subclasses the Dialog class, and provides support for a number of pre-built dialog types that can be easily shown to users to prompt for a response.

Wraps a JavaFX Alert.

Example of displaying an information dialog:

new Alert(AlertType.Information) {
    title = "Information Dialog"
    headerText = "Look, an Information Dialog"
    contentText = "I have a great message for you!"
  }.showAndWait()

A bit more elaborated example that is using a custom buttons:

val One = new ButtonType("One")
val Two = new ButtonType("Two")
val Three = new ButtonType("Three")

val alert = new Alert(AlertType.Confirmation) {
  title = "Confirmation Dialog with Custom Actions"
  headerText = "Look, a Confirmation Dialog with Custom Actions"
  contentText = "Choose your option."
  buttonTypes = Seq(One, Two, Three, ButtonType.Cancel)
}

val result = alert.showAndWait()
result match {
  case Some(One)   => println("... user chose \"One\"")
  case Some(Two)   => println("... user chose \"Two\"")
  case Some(Three) => println("... user chose \"Three\"")
  case _           => println("... user chose CANCEL or closed the dialog")
}

A ButtonBar is essentially a HBox, with the additional functionality for operating system specific button placement.

The ButtonType is used to specify which buttons should be shown to users in the dialogs.

A dialog that shows a list of choices to the user, from which they can pick one item at most.

Wraps JavaFX ComboBox, an implementation of the ComboBoxBase abstract class for the most common form of ComboBox, where a popup list is shown to users providing them with a choice that they may select from.

On top of ComboBoxBase, the ComboBox class introduces additional API. Most importantly, it adds an items property that works in much the same way as the ListView items property. In other words, it is the content of the items list that is displayed to users when they click on the ComboBox button.

It is not recommended to add Nodes as ComboBox items. ScalaFX provides for a convenient customization of a ComboBox content. Required Node or other customization is add ed through cell factory. Following code will show colored Rectangle representing item's Color

val comboBox = new ComboBox[Color] {
  items = Seq(Color.Red, Color.Green, Color.Blue)
  // Custom factory displaying list items are colored rectangles
  // `color` is the value of the item displayed
  cellFactory = (cell, color) => {
    cell.contentDisplay = ContentDisplay.GraphicOnly
    cell.graphic = Rectangle(10, 10, color)
  }
}

A MenuItem that allows for arbitrary nodes to be embedded within it, by assigning a Node to the content property.

Wraps a JavaFX CustomMenuItem.

Helper trait for converting dialog return type. Not intended for separate use.

The DatePicker control allows the user to enter a date as text or to select a date from a calendar popup. The calendar is based on either the standard ISO-8601 chronology or any of the other chronology classes defined in the java.time.chrono package.

A Dialog wraps a DialogPane and provides the necessary API to present it to end users.

Event related to dialog showing/hiding actions. Wraps a JavaFX DialogEvent.

DialogPane should be considered to be the root node displayed within a Dialog instance.

Wraps a JavaFX FocusModel.

A ListView displays a horizontal or vertical list of items from which the user may select, or with which the user may interact. A ListView is able to have its generic type set to represent the type of data in the backing model.

Wraps JavaFX ResizeFeaturesBase.

Wraps JavaFX ScrollToEvent.

A MenuItem that as the name suggests allows for a horizontal Separator to be embedded within it, by assigning a Separator to the content property of the CustomMenuItem.

Wraps a JavaFX SeparatorMenuItem.

Wraps a JavaFX SortEvent.

A single line text field that lets the user select a number or an object value from an ordered sequence.

A TreeTableView is made up of a number of TreeTableColumn instances. Each TreeTableColumn in a TreeTableView is responsible for displaying (and editing) the contents of that column.

Wraps a JavaFX TreeTableColumn

Wraps a JavaFX TreeTablePosition.

Wraps a JavaFX TreeTableRow.

The TreeTableView control is designed to visualize an unlimited number of rows of data, broken out into columns. The TreeTableView control is conceptually very similar to the TreeView and TableView controls, and as you read on you'll come to see the APIs are largely the same. However, to give a high-level overview, you'll note that the TreeTableView uses the same TreeItem API as TreeView, and that you therefore are required to simply set the root node in the TreeTableView. Similarly, the TreeTableView control makes use of the same TableColumn-based approach that the TableView control uses, except instead of using the TableView-specific TableColumn class, you should instead use the TreeTableView-specific TreeTableColumn class instead.

Wraps a JavaFX http://docs.oracle.com/javase/8/javafx/api/javafx/scene/control/TreeTableView.TreeTableView.html

The TreeView control provides a view on to a tree root (of type TreeItem). By using a TreeView, it is possible to drill down into the children of a TreeItem, recursively until a TreeItem has no children (that is, it is a leaf node in the tree). To facilitate this, unlike controls like ListView, in TreeView it is necessary to only specify the root node.

For more information on building up a tree using this approach, refer to the TreeItem class documentation. Briefly, to create a TreeView, you should do something along the lines of the following:

val rootItem = new TreeItem("Root Node") {
  expanded = true
  children ++= Seq(
    new TreeItem("Item 1"),
    new TreeItem("Item 2"),
    new TreeItem("Item 3")
  )
}

val treeView = new TreeView[String] {
  root = rootItem
}
