Question

Write a JavaFX application that allows the user to display an image out of three based on a radio button choice. Make sure to use SetImage somewhere in the program

Answer 1

Solution:

Processing Events for Radio Buttons:

The application perform an action when one of the radio buttons in the group is selected.

Example:

ImageView image = new ImageView();

rb1.setUserData("Home")

rb2.setUserData("Calender");

rb3.setUserData("Contacts");

final ToggleGroup group = new ToggleGroup();

group.selectedToggleProperty().addListner(new ChangeListner<Toggle>(){

public void changed (ObservableValue<? extends Toggle> ov,

Toggle old_toggle, Toggle new_toggle) {

if (group.getSelectedToggle () != null) {

final Image image = new Image (

getClass ().getResourceAsStream(

group.getSelectedToggle ().getUserData ().toString () + ".jpg"

)

);

icon.setImage(image);

}

}

});
