Deleting label in vBox

[John McAlpine]

Is there a way to delete a node from inside a vBox?

So far i've tried this

vBoxName.getChildren().remove(labelVariable);

and

labelName.getParent().getChildren().remove(labelName);

but getChildren is protected in this latter case and the other doesnt seem to be working.

I'm hoping by deleting it, the other nodes will also move up in the vbox to occupy the freed space
Thanks!

In SceneBuilder, point the mouse at the node you want to remove, right-click, and select Delete.

I have an object that's going to have a bunch of randomized fields, and it may or may not contain certain fields on instantiation depending on the subclass that gets generated.

I need to be able to remove the node from the controller

I found another solution that is less convoluted than this one, thanks again for the help

Great!  Would you mind posting your solution so that others can benefit from it?

I had a problem where there was a node (Label) in my vertical box I wanted to get rid of. I can set it to be not visible but that results in a gap in my list, I found a command called "toFront" which puts the Label at the bottom of my list, then I can set its visibility to OFF and it appears to be deleted

labelVariableName.toFront();
labelVariableName.setVisible(false);

If you're interested in actually removing a label, here's a complete program to show you how to do that.  You would either need the Label object itself or a way of distinguishing one label from all the others.

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;

public class TestDeleteLabel extends Application {
	
	public static void main(String[] args) {
		launch(args);
	}

	@Override
	public void start(Stage stage) throws Exception {
		Label label1 = new Label("Label One");
		Label label2 = new Label("Label Two");
		Label label3 = new Label("Label Three");
		Button button = new Button("Press Me");
		button.setOnAction(ae -> buttonAction(stage, label2));
		HBox root = new HBox();
		root.getChildren().addAll(label1, label2, label3, button);
		Scene scene = new Scene(root);
		stage.setScene(scene);
		stage.show();
	}

	private void buttonAction(Stage stage, Label label) {
		Scene scene = stage.getScene();
		HBox root = (HBox) scene.getRoot();
		root.getChildren().remove(label);
	}
}
