JavaFX CheckBox

The Check Box is used to provide more than one choices to the user. It can be used in a scenario where the user is prompted to select more than one option or the user wants to select multiple options.

It is different from the radiobutton in the sense that, we can select more than one checkboxes in a scenerio.

Instantiate javafx.scene.control.CheckBox class to implement CheckBox.

Use the following line in the code to create a blank CheckBox.

Use the following line to attach a label with the checkbox.

We can change the CheckBox Label at any time by calling an instance method setText(“text”). We can make it selected by calling setSelected(“true”)

The following code implements CheckBox into our application.

  package application;  import javafx.application.Application;  import javafx.scene.Scene;  import javafx.scene.control.CheckBox;  import javafx.scene.control.Label;  import javafx.scene.layout.HBox;  import javafx.stage.Stage;  public class CheckBoxTest extends Application {      public static void main(String[] args) {  launch(args);  }    @Override  public void start(Stage primaryStage) throws Exception {  // TODO Auto-generated method stub  Label l = new Label(“What do you listen:     “);  CheckBox c1 = new CheckBox(“Radio one”);  CheckBox c2 = new CheckBox(“Radio Mirchi”);  CheckBox c3 = new CheckBox(“Red FM”);  CheckBox c4 = new CheckBox(“FM GOLD”);  HBox root = new HBox();  root.getChildren().addAll(l,c1,c2,c3,c4);  root.setSpacing(5);  Scene scene=new Scene(root,800,200);  primaryStage.setScene(scene);  primaryStage.setTitle(“CheckBox Example”);  primaryStage.show();  }  }
