[FIXED] Creating multiple stages in JavaFX

Issue

I am trying to create multiple stages using different classes, whereby I can have another window being brought up by a click of a button, but this window should be in a different class.

I used to do this in Java where I would create an object of the class in the buttons action and use the name of the object to set the new JFrame visible, but modal to the main JFrame. I tried the same in JavaFX but it failed to work.

I have two different classes and both are in different stages, but I just can't use one stage to display the other stages. I only know to use one class whereby I would create another stage in the action handler method, but this makes the code very long and too complicated.

P.S. what I am trying to accomplish is not multiple screens in the same window. but different windows (stages), and I prefer not to use FXML files, but java files using netbeans.

Any help would be greatly appreciated.

Solution

So you want each class to be a sub-class of a Stage. I'll give you two Stages and how to interact with each other.

public class FirstStage extends Stage{
Button openOther = new Button("Open other Stage");
HBox x = new HBox();

FirstStage(){
    x.getChildren().add(openOther);
    this.setScene(new Scene(x, 300, 300));
    this.show();

    openOther.setOnAction(new EventHandler<ActionEvent>() {
        @Override
        public void handle(ActionEvent t) {
            new SecondStage();
        }//end action
    });
    }
}

For the second Stage,

public class SecondStage extends Stage {
Label x = new Label("Second stage");
VBox y = new VBox();

SecondStage(){
    y.getChildren().add(x);
    this.setScene(new Scene(y, 300, 300));
    this.show();
   }    
}

And call from main the first stage:

@Override
public void start(Stage primaryStage){
    new FirstClass();
}
