TreeItem

Trait used for handle events manipulation. JavaFX class wrapped must have methods defined in scalafx.event.EventHandlerDelegate1.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])
def buildEventDispatchChain(chain: jfxe.EventDispatchChain): jfxe.EventDispatchChain

Creates a TreeItem with the value property set to the provided object.

Creates a TreeItem with the value property set to the provided object, and the graphic set to the provided Node.

The children of this TreeItem.

The expanded state of this TreeItem.

The node that is generally shown to the left of the value property.

Represents the TreeItem leaf property, which is true if the TreeItem has no children.

Returns the next sibling of the TreeItem.

Returns the next sibling after the given node.

A property that represents the parent of this TreeItem.

Returns the previous sibling of the TreeItem.

Returns the previous sibling previous the given node.

A property representing the application-specific data contained within this TreeItem.

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

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.

Construct an event dispatch chain for this target.

Verifies if a object is equals to this delegate.

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") }

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") }

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.

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.
