scalafx.scene.control

Alert

class Alert extends Dialog[javafx.scene.control.ButtonType] with SFXDelegate[javafx.scene.control.Alert]

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")
}

Instance Constructors

  1. new Alert(alertType: AlertType, contentText: String, buttons: ButtonType*)

    Creates an alert with the given contentText, ButtonTypes, and AlertType (refer to the AlertType documentation for clarification over which one is most appropriate).

    Creates an alert with the given contentText, ButtonTypes, and AlertType (refer to the AlertType documentation for clarification over which one is most appropriate).

    By passing in a variable number of ButtonType arguments, the developer is directly overriding the default buttons that will be displayed in the dialog, replacing the pre-defined buttons with whatever is specified in the varargs array.

    By passing in an AlertType, default values for the title property, headerText property, graphic property properties are set. Once the Alert is instantiated, developers are able to modify the values of the alert as desired.

  2. new Alert(alertType: AlertType)

    Creates an alert with the given AlertType (refer to the AlertType documentation for clarification over which one is most appropriate).

    Creates an alert with the given AlertType (refer to the AlertType documentation for clarification over which one is most appropriate).

    By passing in an AlertType, default values for the title property, headerText property, graphic property properties are set. Once the Alert is instantiated, developers are able to modify the values of the alert as desired.

  9. def buildEventDispatchChain(tail: EventDispatchChain): EventDispatchChain

    Construct an event dispatch chain for this target.

    Construct an event dispatch chain for this target. The event dispatch chain contains event dispatchers which might be interested in processing of events targeted at this EventTarget. This event target is not automatically added to the chain, so if it wants to process events, it needs to add an EventDispatcher for itself to the chain.

    In the case the event target is part of some hierarchy, the chain for it is usually built from event dispatchers collected from the root of the hierarchy to the event target.

    The event dispatch chain is constructed by modifications to the provided initial event dispatch chain. The returned chain should have the initial chain at its end so the dispatchers should be prepended to the initial chain.

    The caller shouldn't assume that the initial chain remains unchanged nor that the returned value will reference a different chain.

    tail

    the initial chain to build from

    returns

    the resulting event dispatch chain for this target

    API to convert the scalafx.scene.control.ButtonType that the user clicked on into a result that can be returned via the scalafx.scene.control.Dialog.result property. This is necessary as scalafx.scene.control.ButtonType represents the visual button within the dialog, and do not know how to map themselves to a valid result - that is a requirement of the dialog implementation by making use of the result converter. In some cases, the result type of a Dialog subclass is ButtonType (which means that the result converter can be null), but in some cases (where the result type, R, is not ButtonType or Void), this callback must be specified.
