RadioButton

The Radio Button is used to provide various options to the user. The user can only choose one option among all. A radio button is either selected or deselected. It can be used in a scenario of multiple choice questions in the quiz where only one option needs to be chosen by the student.

The following code shows how one radio button is selected from a toggle group.

package application;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.RadioButton;
import javafx.scene.control.ToggleGroup;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class RadioButtonTest extends Application {

	
public static void main(String[] args) {
launch(args);	
}

@Override
public void start(Stage primaryStage) throws Exception {
	// TODO Auto-generated method stub
	ToggleGroup group = new ToggleGroup();
	RadioButton button1 = new RadioButton("option 1");
	RadioButton button2 = new RadioButton("option 2");
	RadioButton button3 = new RadioButton("option 3");
	RadioButton button4 = new RadioButton("option 4");
	button1.setToggleGroup(group);
	button2.setToggleGroup(group);
	button3.setToggleGroup(group);
	button4.setToggleGroup(group);
	VBox root=new VBox();
	root.setSpacing(10);
	root.getChildren().addAll(button1,button2,button3,button4);
	Scene scene=new Scene(root,400,300);
	primaryStage.setScene(scene);
	primaryStage.setTitle("Radio Button Example");
	primaryStage.show();
}
}
