The FXML parser will verify that it can parse the specified. Optionally, you can append the version of the FXML in the namespace URI. FXML uses special elements and attribute names, which must be qualified with the “fx” namespace prefix. For the most part, the FXML parser will figure out the tag names such as tag names that are classes, properties of the classes, and so on. It uses a namespace that needs to be specified using the namespace prefix “fx”. The following FXML creates a TextField and sets its prefWidth property using an attribute: įXML does not have an XML schema. The attribute name or the property element name is the same as the name of the property being set. A property for an object can be set in FXML if the property declaration follows the JavaBean conventions. You can set properties for Java objects in FXML. ![]() The following import processing instructions import all classes from the and java.lang packages: The following processing instructions import the VBox, Label, and Button classes: 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.
