JavaFX | Tab Class

Tab class is a part of JavaFX. Tab class creates an object that is contained in TabPane. A Tab can contain any node as its content. A TabPane can contain multiple tabs. When the user clicks on the tab the content of the tab is made visible to the user.

Constructors of the class:

1. Tab(): Creates a new empty tab.
2. Tab(String t): Creates a new tab with specified title.
3. Tab(String t, Node c): Creates a new tab with specified title and content.

Commonly Used Methods:

Below programs illustrate the use of Tab class:

1. Java program to create a tab and add it to the TabPane: In this program we will create a Tab named tab_1. We will also create a Label named label. We will add the label to the tab by using the function setContent(). The title of the tab will be passed as arguments. We will create a TabPane named tabpane and add the tab to the tabpane. Now, we will add the tabpane to the scene and add the scene to the stage and display the stage using the show() function.

   
   

   
   
   

   // Java program to create a tab  // and add it to the TabPane import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.layout.*; import javafx.stage.Stage; import javafx.scene.Group; import javafx.scene.control.*;    public class Tab_1 extends Application {        // launch the application     public void start(Stage stage)     {            // set title for the stage         stage.setTitle("creating Tab");            // create Tab         Tab tab_1 = new Tab("Tab_1");            // create a label         Label label = new Label(" This is a tab ");            // add label to the tab         tab_1.setContent(label);            // add tab         // create a tabpane         TabPane tabpane = new TabPane(tab_1);            // create a scene         Scene scene = new Scene(tabpane, 600, 500);            // set the scene         stage.setScene(scene);            stage.show();     }        // Main Method     public static void main(String args[])     {            // launch the application         launch(args);     } }

   Output:
   

2. Java program to create a tab, add graphic(in the tab) to it and add it to the TabPane: In this program we will create a Tab named tab_1. We will also create a Label named label. We will add label to the tab by using the function setContent(). The title of the tab will be passed as arguments. We will create a FileInputStream named input to import the image. An Image will be created named image from the file input stream, then we will create an ImageView named imageview from the imported image. We will add this imageview to the tab using the setGraphic() function. We will create a TabPane named tabpane and add the tab to the tabpane . Now, we will add the tabpane to the scene and add the scene to the stage and display the stage using the show() function.
