I have a MediaView
and I want to play a fullscreen video .. i just can't find the right parent to my MediaView
.. it gives me this error javafx.scene.media.MediaView cannot be cast to javafx.scene.Parent
that's my fxml file
<?xml version="1.0" encoding="UTF-8"?>
<?import java.lang.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.media.*?>
<?import javafx.scene.layout.AnchorPane?>
<MediaView fx:id="astrolabe_intro" fitHeight="200.0" fitWidth="200.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8" fx:controller="astrolabe.astrolabe_introController" />
and that's my controller
import java.io.File;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.fxml.Initializable;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
public class astrolabe_introController implements Initializable {
String workingDir = System.getProperty("user.dir");
File video = new File(workingDir, "src/astrolabe/img/astrolab_movie.mp4");
Media m = new Media(video.toURI().toString());
MediaPlayer astrolabe_intro = new MediaPlayer(m);
@Override
public void initialize(URL arg0, ResourceBundle arg1) {
// TODO Auto-generated method stub
astrolabe_intro.play();
}
}
You must not use MediaView
as the root node, because it doesn't extend from Parent
. Try to wrap your MediaView
inside a Pane
. For example :
<?xml version="1.0" encoding="UTF-8"?>
<?import java.lang.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.media.*?>
<?import javafx.scene.layout.AnchorPane?>
<AnchorPane fx:id="anchorPane" fitHeight="200.0" fitWidth="200.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8" fx:controller="astrolabe.astrolabe_introController" >
<MediaView fx:id="astrolabe_intro"/>
</AnchorPane>
NB You might also want to define different reference name for your MediaView
and MediaPlayer
. In the above example you have defined fx:id
of MediaView
and ref for MediaPlayer
as astrolabe_intro
A simple example of MediaView/MediaPlayer is here and FXML is here
