如何使用scala创建一个FXML控制器？

import javafx.fxml.FXML
import javafx.scene.control.Button

class MyController {
  @FXML
  private var myButton: Button = _
}

<Button fx:id="myButton" text="Click Me" />

import javafx.fxml.FXMLLoader
import javafx.scene.Parent
import javafx.scene.Scene

val loader = new FXMLLoader(getClass.getResource("path/to/fxml/file.fxml"))
val root: Parent = loader.load()
val scene = new Scene(root)

import javafx.application.Application
import javafx.stage.Stage

class MyApp extends Application {
  override def start(stage: Stage): Unit = {
    val loader = new FXMLLoader(getClass.getResource("path/to/fxml/file.fxml"))
    val root: Parent = loader.load()
    val scene = new Scene(root)
    
    stage.setScene(scene)
    stage.show()
  }
}

object MyApp {
  def main(args: Array[String]): Unit = {
    Application.launch(classOf[MyApp], args: _*)
  }
}
