trait EventHandlerDelegate extends AnyRef

Trait used for handle events manipulation. JavaFX class wrapped must have methods defined in scalafx.event.EventHandlerDelegate.EventHandled Type:

def addEventHandler   [E <: jfxe.Event](eventType: jfxe.EventType[E], eventHandler: jfxe.EventHandler[_ >: E])
def removeEventHandler[E <: jfxe.Event](eventType: jfxe.EventType[E], eventHandler: jfxe.EventHandler[_ >: E])
def addEventFilter    [E <: jfxe.Event](eventType: jfxe.EventType[E], eventHandler: jfxe.EventHandler[_ >: E])
def removeEventFilter [E <: jfxe.Event](eventType: jfxe.EventType[E], eventHandler: jfxe.EventHandler[_ >: E])

  6. def addEventFilter[E <: javafx.event.Event](eventType: javafx.event.EventType[E], eventHandler: EventHandler[_ >: E]): Unit

    Registers an event filter to this task.

    Registers an event filter to this task. Registered event filters get an event before any associated event handlers.

    E

    Event class

    eventType

    the type of the events to receive by the filter

    eventHandler

    the filter to register that will filter event

  7. def addEventHandler[E <: javafx.event.Event](eventType: javafx.event.EventType[E], eventHandler: EventHandler[_ >: E]): Unit

    Registers an event handler to this task.

    Registers an event handler to this task. Any event filters are first processed, then the specified onFoo event handlers, and finally any event handlers registered by this method. As with other events in the scene graph, if an event is consumed, it will not continue dispatching.

    E

    Event class

    eventType

    the type of the events to receive by the handler

    eventHandler

    the handler to register that will manipulate event

  9. def buildEventDispatchChain(chain: javafx.event.EventDispatchChain): javafx.event.EventDispatchChain

  13. def filterEvent[J <: javafx.event.Event, S <: Event with SFXDelegate[J]](eventType: EventType[J])(filter: FilterMagnet[J, S]): Subscription

    Registers an event filter.

    Registers an event filter. Registered event filters get an event before any associated event handlers.

    Example of filtering mouse events

    pane.filterEvent(MouseEvent.Any) {
  me: MouseEvent => {
    me.eventType match {
      case MouseEvent.MousePressed => {
        ...
      }
      case MouseEvent.MouseDragged => {
        ...
      }
      case _ => {
        ...
      }
    }
  }
}

    or

    pane.filterEvent(MouseEvent.Any) { () => println("Some mouse event handled") }
    J

    type JavaFX delegate of the event

    S

    ScalaFX type for J type wrapper.

    eventType

    type of events that will be handled.

    filter

    code handling the event, see examples above.

  16. def handleEvent[J <: javafx.event.Event, S <: Event with SFXDelegate[J]](eventType: EventType[J])(handler: HandlerMagnet[J, S]): Subscription

    Registers an event handler.

    Registers an event handler. The handler is called when the node receives an Event of the specified type during the bubbling phase of event delivery.

    Example of handling mouse events

    pane.handleEvent(MouseEvent.Any) {
  me: MouseEvent => {
    me.eventType match {
      case MouseEvent.MousePressed => ...
      case MouseEvent.MouseDragged => ...
      case _                       => {}
    }
  }
}

    or

    pane.handleEvent(MouseEvent.Any) { () => println("Some mouse event handled") }
    J

    type JavaFX delegate of the event

    S

    ScalaFX type for J type wrapper.

    eventType

    type of events that will be handled.

    handler

    code handling the event, see examples above.

    returns

    Returns a subscription that can be used to cancel/remove this event handler

  22. def removeEventFilter[E <: javafx.event.Event](eventType: javafx.event.EventType[E], eventHandler: EventHandler[_ >: E]): Unit

    Unregisters a previously registered event filter from this task.

    Unregisters a previously registered event filter from this task. One filter might have been registered for different event types, so the caller needs to specify the particular event type from which to unregister the filter.

    E

    Event class

    eventType

    the event type from which to unregister

    eventHandler

    the filter to unregister

  23. def removeEventHandler[E <: javafx.event.Event](eventType: javafx.event.EventType[E], eventHandler: EventHandler[_ >: E]): Unit

    Unregisters a previously registered event handler from this task.

    Unregisters a previously registered event handler from this task. One handler might have been registered for different event types, so the caller needs to specify the particular event type from which to unregister the handler.

    E

    Event class

    eventType

    the event type from which to unregister

    eventHandler

    the handler to unregister
