JavaFX | TextFlow Class

TextFlow class is a part of JavaFX. TextFlow class is designed to lay out rich text. It can be used to layout several Text nodes in a single text flow. TextFlow class extends Pane class.

Constructors of the class:

1. TextFlow(): Create a new textflow object.
2. TextFlow(Node… c): Create a new textflow object with specified nodes.

Commonly Used Methods:

Below programs illustrate the use of TextFlow class:

1. Java program to create a TextFlow and add text object to it: In this program we will create a TextFlow named text_flow and two Text named text_1 and text_2. Set the fill and font using setFill() and setFont(). We will add the text to the text_flow using the getChildren().add() function. Add the text_flow to the scene and scene to the stage. Call the show() function to display the final results.

   
   

   
   
   

   // Java program to create a TextFlow and  // add text object to it . import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.*; import javafx.scene.layout.*; import javafx.stage.Stage; import javafx.event.ActionEvent; import javafx.scene.paint.*; import javafx.scene.text.*; import javafx.scene.web.*; import javafx.scene.layout.*; import javafx.scene.shape.*;    public class TextFlow_0 extends Application {        // launch the application     public void start(Stage stage)     {            try {                // set title for the stage             stage.setTitle("TextFlow");                // create TextFlow             TextFlow text_flow = new TextFlow();                // create text             Text text_1 = new Text("Lazyroar\n");                // set the text color             text_1.setFill(Color.RED);                // set font of the text             text_1.setFont(Font.font("Verdana", 25));                // create text             Text text_2 = new Text("The computer science portal for geeks");                // set the text color             text_2.setFill(Color.BLUE);                // set font of the text             text_2.setFont(Font.font("Helvetica", FontPosture.ITALIC, 15));                // add text to textflow             text_flow.getChildren().add(text_1);             text_flow.getChildren().add(text_2);                // create a scene             Scene scene = new Scene(text_flow, 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 TextFlow and add text object to it, set text Alignment and set line spacing of the text flow: In this program we will create a TextFlow named text_flow and two Text named text_1 and text_2. Set the fill and font using setFill() and setFont(). Set TextAlignment using setTextAlignment() and set the line spacing using the setLineSpacing() function. Add the text to the text_flow using the getChildren().add() function. Add the text_flow to the Vbox. Add the vbox scene and the scene to the stage. Call the show() function to display the final results.
