JavaFX Tooltip

Introduction

Hello and welcome, readers! We hope you are doing well.  

Today, we will discuss the JavaFX Tooltip. After completing this article, you will clearly understand the JavaFX Tooltip. So follow the article till the end. 

So, without further ado, let’s jump into the article.

JavaFX Tooltip

A tooltip is included in the JavaFX package. A tooltip is utilised to display further information when the user's mouse is over a component. A tooltip can be connected to every component and a specific area of the screen. The Tooltip class's constructors include

1. Tooltip(): Generates a tooltip with a text value of nothing.
2. Tooltip(String t): This method generates a tooltip with the given text.

It would help if you first created a Tooltip instance before you can use the JavaFX Tooltip class. Here's an example of how to make a JavaFX Tooltip instance:

Tooltip tooltip1 = new Tooltip("Creates a new file");

Methods

Implementation

To implement the demo application, we need to follow the steps below.

1. Create a demo project in any IDE that supports Java Web applications, such as NetBeans. Choose File, then New Project from the NetBeans IDE Main menu.
2. Select the web application project type from the Java with Maven category.

1. Choose FXML JavaFX Maven Archetype and pick any practical name for your project and packages.
2. Choose Java EE 7 for the web and the GlassFish Server.
3. Modify the “App.Java” file on the project folder, as shown in the image below.
4. Compile and execute the application to see if it is being compiled in the previously configured environment.
5. Create the web application and deploy it as a war file via the GlassFish server. After execution, the program's output should be displayed in the default browser window.
    

Folder Structure

As previously stated, the folder structure should resemble the image below:

Code

package com.mycompany.javafxdemo;

import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
import javafx.scene.control.Tooltip;
import javafx.scene.layout.HBox;
public class App extends Application {
   @Override
   public void start(Stage stage) {
      //Setting the labels
      Label label1 = new Label("First Name: ");
      
      //Defining the textfield
      TextField textField = new TextField();
      
      //Defining thr tool tip Text
      Tooltip toolTipTxt = new Tooltip("Enter your first name only.");
      Tooltip.install(textField, toolTipTxt);
      
      //Setting the tool tip to the text field
      HBox box = new HBox(4);
      box.setPadding(new Insets(20, 5 , 5, 40));
      box.getChildren().addAll(label1, textField);
      
      //Setting the application scene and stage
      Scene scene = new Scene(box, 490, 135, Color.BLACK);
      stage.setTitle("Tooltip Demonstration");
      stage.setScene(scene);
      stage.show();
   }
   public static void main(String args[]){
      launch(args);
   }
}

Output 1(Before Hovering over TextField)

Output 2(After Hovering Over TextField)
