JavaFX | TextFlow Class

0 0 3 minutes read

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:

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

Commonly Used Methods:

Method	Explanation
getLineSpacing()	Returns the line spacing of the text flow
getTextAlignment()	Returns the text alignment of the text flow
setLineSpacing(double s)	Set line spacing of the text flow .
setTextAlignment(TextAlignment v)	Sets the text alignment of the text flow.

Below programs illustrate the use of TextFlow class:

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.

            // 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

Output:

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.
