How to add 1 to the Text of a Tab in every time on click on a button? in JavaFX

Question

i have a TabPane and Button once on click on this button should add a new Tab to the TabPane like: Tab1 for the second time on click on the button should add another tab to the TabPane like: Tab2 . So while clicking on this button should add 1 to the text of the Tab in every time. this is my code:

 butser.setOnAction( new EventHandler<ActionEvent>()  {
    @Override
    public void handle( ActionEvent event )
    {
        int hu = 0 ;
        Tab tab = new Tab( "Tab" + hu);
        tabs.getTabs().add( tab  );

    }
} ); 

How i can do that in javafx and thank you soooo much :)

Answer 1

Try this

private int lastNumber = 0;


@Override
public void start( Stage stage )
{
    TabPane tabPane = new TabPane();
    Button b = new Button( "add" );
    b.setOnAction( new EventHandler<ActionEvent>()
    {
        @Override
        public void handle( ActionEvent event )
        {
            Tab tab = new Tab( "Tab" + lastNumber );
            tabPane.getTabs().add( tab );
            lastNumber++;
        }
    } );

    Scene scene = new Scene( new VBox( b, tabPane ), 200, 100 );
    stage.setScene( scene );
    stage.show();
}
