JavaFx: Button: setGraphic: Add icon to a button

In my previous post, I explained how to create a button widget using Button constructor. We can create a button with text + graphic content (image icon) using below Button constructor.

public Button(String text, Node graphic)

Ex

InputStream is = new FileInputStream(imageFilePath);

Image image = new Image(is);

Button button = new Button("Search Button3", new ImageView(image));

Button class also provides 'setGraphic' method to set the icon to a button.

Ex

InputStream is = new FileInputStream(imageFilePath);

Image image = new Image(is);

Button button = new Button("Search Button");

button.setGraphic(new ImageView(image));

Find the below working application.

ButtonApp.java

package com.sample.demos;

import static javafx.geometry.Pos.CENTER;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.InputStream;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class ButtonApp extends Application {
 private static String imageFilePath = "C:\\Users\\krishna\\Documents\\Study\\javaFX\\search.png";

 @Override
 public void start(Stage primaryStage) throws FileNotFoundException {

  InputStream is = new FileInputStream(imageFilePath);
  Image image = new Image(is);
  Button button = new Button("Search Button");
  button.setGraphic(new ImageView(image));

  VBox vBox = new VBox(10, button);
  vBox.setAlignment(CENTER);

  Scene scene = new Scene(vBox, 400, 400);

  /* Set the scene to primaryStage, and call the show method */
  primaryStage.setTitle("JavaFX Button Example");
  primaryStage.setScene(scene);
  primaryStage.show();
 }

}

TestFX.java

package com.sample.demos;

import javafx.application.Application;

public class TestFX {
 public static void main(String args[]) {
  Application.launch(ButtonApp.class, args);
 }
}
