I am making a children's programming platform like Scratch using JavaFX. I have a series of commands, and when I click them they enter my "CodeBox" which extends the standard JavaFX class VBox. Of course, I want to add "save" and "resume" feature to my code. But as JavaFX objects are not Serializable, I am facing deep trouble.

To try, I have extended JavaFX Button class

public class fButton extends Button implements Serializable{

Now I want to know if there is any way to save and retrieve all these objects or if there is a better way.

Serializing UI components in order to save state is generally a very bad way of doing things, as it creates an insanely close coupling between your UI and your application state.

What if you want to swap out a VBox for a custom StackPane component for instance in a future release? That's a very realistic scenario - perhaps you want to decorate those VBoxes for instance by overlaying some other component - yet doing so instantly wrecks anyone's ability to then load a file saved with a previous release.

I'd argue your backend state should be separated from the UI entirely - you can then serialize the backend state alone via whatever means you fancy (JSON, XML, some other Java serializer, etc.) and rely on your rendering / transformer layer to create the relevant components for your backend state.

You then decouple the two, allow for whatever serialization you like, and give much more scope for changing the UI layer without upsetting your backend model too much.

Many Swing components can display icons. Usually, icons are implemented as instances of the ImageIcon class. Solving Common Component Problems. This section discusses solutions to common component-related problems. If you are interested in using JavaFX to create your GUI, see Using JavaFX Charts and Using JavaFX UI Controls.

For saving and loading I would recommend using JSON or XML files. Have a separate folder for images. When you save the file, save the image file path. You can then attach the image or text when loading.

Button button = new Button();
button.setWrapText(true); //needed for text buttons
String imagePath = //this is the path to the image (save this)
Image buttonImage = new Image(imagePath);
        if (!buttonImage.isError()) {
            button.setGraphic(new ImageView(buttonImage));
        }

How to Use Icons (The Java™ Tutorials > Creating a GUI With JFC , Swing provides a particularly useful implementation of the Icon interface: or URL to an ImageIcon constructor, processing is blocked until after the image data is The following figures illustrate a few of the ways these files can be configured: If you are writing a real-world application, it is likely (and recommended) that  JavaFX (GUI) Programming. The JavaFX is a new framework intended to support desktop applications and web browsers. It is generally a Java platform for creating rich internet applications that can run on a large variety of devices. Since this is a framework for Java, the code written is not machine dependent.

File Input/Output in a JavaFX Application – curbsidebanter, You can use the APIs in the java.io package to read character data or When you click the button, whatever is entered into the text field is saved to a file. After that, the file is opened, read, and its text displayed in the window on the right. To write the input text to a file, the text is retrieved from the textField  You can return to Outlook later and find the unsent message. To manually save a draft of a message. Do one of the following: On the Quick Access Toolbar, click Save. On the File tab, click Save. To return to a saved draft of a message. In Mail, in the Folder pane, click Drafts, and then double-click the message.

JavaFX, JavaFX is a software platform for creating and delivering desktop applications, as well as rich JavaFX applications could run on any desktop that could run Java SE or on any mobile JavaFX scene builder: This was introduced for Java FX 2.1 and later. This information is saved as an FXML file, a special XML format. You can drag and drop GUI elements on the panels which are later saved as FXML files and could be loaded within your source code. If you are using Intellij the SceneBuilder is already integrated in the IDE and you can switch between FXML or RAD tool with one click.

When the UI controls are being created (new VBox (), new Scene(), primaryStage. setPrefWidth(200); Button saveButton = new Button("Save"); HBox The code can be tested in a single .java file. In the show function, the window handles of all controls on the page can be retrieved from a Modern UI variable. A list of the variables names is not yet available. For now, refer to the source files of the Modern UI 2.

Using URL is more flexible as it can access resources in a JAR file, and You can retrieve this Image object via the ImageIcon 's getImage() method. The Image object is used in the drawImage() method for custom drawing (which shall be discussed later). The extension can be used to import ingredients from Tasty, which you can later use in your shopping list. I chose this example so we can see how to implement a popup with various UI elements with

  • "another command" - What commands did you use? Provide them.
  • unrelated to your problem: please learn java naming conventions and stick to them
  • don't save the controls, save their states
  • New to Java... My all other classes follow Java naming conventions.
