An import processing instruction is used to import a class or all classes from a package. However, in FXML, you need to import classes from all packages, including the java.lang package. In Java programs, you do not need to import classes from the java.lang package. To use the simple names of Java classes in FXML, you must import the classes as you do in Java programs. It will create a VBox with two labels, a TextField, a TextArea and a Button. This defines the basic structure of the object-graph for our application. You can add a Label and a Button and other elements to the VBox as follows: In FXML, layout panes have children as their child elements. The above FXML can be rewritten using the fully qualified class name: The above element will create an object of the VBox class. For example, if a tag name is the simple or fullqualified name of a class, the tag will create an object of that class. It is easy because FXML has a few rules explaining what constitutes a tag name.

It is difficult because there is no documentation for FXML tags. How do you know that to represent a VBox in the object-graph, you need to use a tag in FXML? It is both difficult and easy. Therefore, the root element of your FXML would be: The top-level object of the above example is a VBox.

The root element of the FXML document is the top-level object in the object-graph. The following examples uses Java SE 7 and JavaFX 2.2.
