ScalaFxでAnchorPaneの記述を他のものと揃えるためのtrait。

InAnchorPane.scala

package scalafx.scene.layout

import scalafx.scene.Node

trait InAnchorPane { self: Node =>
  def topAnchor: Double = AnchorPane.getTopAnchor(self)
  def topAnchor_=(v: Double) {
    AnchorPane.setTopAnchor(self, v)
  }

  def bottomAnchor: Double = AnchorPane.getBottomAnchor(self)
  def bottomAnchor_=(v: Double) {
    AnchorPane.setBottomAnchor(self, v)
  }

  def leftAnchor: Double = AnchorPane.getLeftAnchor(self)
  def leftAnchor_=(v: Double) {
    AnchorPane.setLeftAnchor(self, v)
  }

  def rightAnchor: Double = AnchorPane.getRightAnchor(self)
  def rightAnchor_=(v: Double) {
    AnchorPane.setRightAnchor(self, v)
  }
}

MyApplication.scala

package app

import scalafx.application.JFXApp
import scalafx.scene.Scene
import scalafx.scene.layout.{InAnchorPane, AnchorPane}
import scalafx.scene.control.TextField

object MyApplication extends JFXApp {

  stage = new JFXApp.PrimaryStage {
    title = "My Application"
    scene = new Scene(
      new AnchorPane {
        prefWidth = 320
        prefHeight = 138
        content = List(
          new TextField with InAnchorPane {
            topAnchor = 18
            leftAnchor = 30
            rightAnchor = 30
          }
        )
      }
    )
  }

}
