JavaFX Tooltip

JavaFX Tooltip

JavaFX Tooltip class can be used to display a small popup containing text when user hovers on a control (subclasses of javafx.scene.control).

In this tutorial, we will learn how to show a JavaFX Tooltip for some of the controls like JavaFX Button, JavaFX Hyperlink, etc.

To create a JavaFX Tooltip, you can use Tooltip class as shown below.

 Tooltip tooltip = new Tooltip("Some text");

You have to import javafx.scene.control.Tooltip in your class to use JavaFX Tooltip.

Example 1 – JavaFX Tooltip – For a Button

In this example, we shall create a Tooltip and Button. And then set the tooltip to button.

JavaFxTooltipTutorial.java

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Tooltip;
import javafx.scene.control.Button;
import javafx.scene.layout.TilePane;
import javafx.stage.Stage;
 
public class JavaFxTooltipTutorial extends Application {
    
    public static void main(String[] args) {
        launch(args);
    }
    
    @Override
    public void start(Stage primaryStage) {
        try {
            // set title
            primaryStage.setTitle("JavaFX Tooltip - tutorialkart.com");
            
            //javafx tooltip
            Tooltip tooltip = new Tooltip("Creates a new file");
            
            //javafx button
            Button button = new Button("Upload");
            //set tooltip for button
            button.setTooltip(tooltip);
            
            // tile pane
            TilePane tilePane = new TilePane();
            
            // add button to the tile pane
            tilePane.getChildren().add(button);
            
            //set up scene
            Scene scene = new Scene(tilePane, 400, 100);
            primaryStage.setScene(scene);
            primaryStage.show();
        } catch(Exception e) {
            e.printStackTrace();
        }
    }
}

Run this application and you should get a window with a button as shown below.

Hover on the button with the cursor and the tooltip reveals itself to show the user the text we intend to.

Example 2 – JavaFX Tooltip – For a Hyperlink

In this example, we shall create a Tooltip and Hyperlink. And then set the tooltip to hyperlink.

JavaFxTooltipTutorial2.java

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Tooltip;
import javafx.scene.control.Hyperlink;
import javafx.scene.layout.TilePane;
import javafx.stage.Stage;
 
public class JavaFxTooltipTutorial2 extends Application {
    
    public static void main(String[] args) {
        launch(args);
    }
    
    @Override
    public void start(Stage primaryStage) {
        try {
            // set title
            primaryStage.setTitle("JavaFX Tooltip - tutorialkart.com");
            
            //javafx tooltip
            Tooltip tooltip = new Tooltip("Best Online Tutorials.");
            
            //javafx hyperlink
            Hyperlink hyperlink = new Hyperlink("www.tutorialkart.com");
            //set tooltip for hyperlink
            hyperlink.setTooltip(tooltip);
            
            // tile pane
            TilePane tilePane = new TilePane();
            
            // add hyperlink to the tile pane
            tilePane.getChildren().add(hyperlink);
            
            //set up scene
            Scene scene = new Scene(tilePane, 400, 100);
            primaryStage.setScene(scene);
            primaryStage.show();
        } catch(Exception e) {
            e.printStackTrace();
        }
    }
}

Run this application and you should get a window with a hyperlink. Hover on the hyperlink with the cursor and the tooltip reveals itself to the user as a popup.

Conclusion

In this JavaFX Tutorial, we learned how to create a Tooltip and use it for JavaFX controls like Button, Hyperlink, etc.
