JavaFX Label

javafx.scene.control.Label class represents label control. As the name suggests, the label is the component that is used to place any text information on the screen. It is mainly used to describe the purpose of the other components to the user. You can not set a focus on the label using the Tab key.

Package: javafx.scene.control

Constructors:

Label(): creates an empty Label 
Label(String text): creates Label with the supplied text 
Label(String text, Node graphics): creates Label with the supplied text and graphics

Adding a Node to the scene graph

The following code implements Label into our Application.

package application;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class LabelTest extends Application {

	@Override
	public void start(Stage primaryStage) throws Exception {
		// TODO Auto-generated method stub
		Label my_label=new Label("This is an example of Label");
		StackPane root = new StackPane(); 
		Scene scene=new Scene(root,300,300);
		root.getChildren().add(my_label);
		primaryStage.setScene(scene);
		primaryStage.setTitle("Label Class Example");
		primaryStage.show();
		
	}
	public static void main(String[] args) {
		launch(args);
	}
}

Output:

Displaying image in a Label

JavaFX allows us to display some graphics next to the label text. There is a constructor in the Label class in which, we can pass any image along with the label text. The example given below is displaying the image in a Label.

package application;

import java.io.FileInputStream;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class LabelTest extends Application {

	@Override
	public void start(Stage primaryStage) throws Exception {
		// TODO Auto-generated method stub
		
		StackPane root = new StackPane(); 
		FileInputStream input= new FileInputStream("/home/javatpoint/Desktop/JavaFX/Images/colored_label.png");
		Image image = new Image(input);
		ImageView imageview=new ImageView(image);
		Label my_label=new Label("Home",imageview);
		Scene scene=new Scene(root,300,300);
		root.getChildren().add(my_label);
		primaryStage.setScene(scene);
		primaryStage.setTitle("Label Class Example");
		primaryStage.show();
		
	}
	public static void main(String[] args) {
		launch(args);
	}
}
