JavaFX | Font Class

Font class is a part of JavaFX. The Font class represents fonts, which are used to render text on the screen. The size of a Font is described as being specified in points which are a real world measurement of approximately 1/72 inch. Font class inherits Object class.

Constructors of the class:

1. Font(double s) : Creates a font object with specified size.
2. Font(String n, double s) : Creates a font object with specified name and size.

Commonly Used Methods:

Below programs illustrate the use of Font Class:

1. Java Program to create a font object and apply it to a text: In this program we will create a Font named font and specify its family, its font weight and size. Apply this font to the text and add this text to the TextFlow named textflow. Create a VBox named vbox and add the textflow to the vbox and add the vbox to the scene and add the scene to stage. Call the show() function to display the results.

   
   

   
   
   

   // Java Program to create a font object  // and apply it to a text import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.*; import javafx.scene.layout.*; import javafx.stage.Stage; import javafx.scene.layout.*; import javafx.scene.paint.*; import javafx.scene.text.*; import javafx.geometry.*; import javafx.scene.layout.*; import javafx.scene.shape.*;    public class Font_1 extends Application {        // launch the application     public void start(Stage stage)     {            try {                // set title for the stage             stage.setTitle("Font");                // create TextFlow             TextFlow text_flow = new TextFlow();                // create text             Text text_1 = new Text("Lazyroar\n");                // set the text color             text_1.setFill(Color.GREEN);                // create a font             Font font = Font.font("Verdana", FontWeight.EXTRA_BOLD, 25);                // set font of the text             text_1.setFont(font);                // set text             text_flow.getChildren().add(text_1);                // set line spacing             text_flow.setLineSpacing(20.0f);                // create VBox             VBox vbox = new VBox(text_flow);                // set alignment of vbox             vbox.setAlignment(Pos.CENTER);                // create a scene             Scene scene = new Scene(vbox, 400, 300);                // set the scene             stage.setScene(scene);                stage.show();         }            catch (Exception e) {                System.out.println(e.getMessage());         }     }        // Main Method     public static void main(String args[])     {            // launch the application         launch(args);     } }

   Output:

   

2. Java Program to create a font object and apply it to a text and allow the user to select the font from the combo box: In this program we will create a Font named font and specify its family, its font weight and size. Apply this font to the text and add this text to the TextFlow named textflow. Create a VBox named vbox and add the textflow to the vbox and add the vbox to the scene and add the scene to stage. Create two combo box and add the font names to one and the font weight to the other and create an EventHandler to handle the events of the combo boxes and set the font to the type specified by the user.
