JavaFX - Check if a checkbox is ticked

I am trying to write some code to determine whether or not my checkbox is ticked, I am aware I can write something like to change its state to checked

checkbox.setSelected(true);

But I want to write something along the lines of

if(checkbox.setSelected(true)){
   write login-username to config file
} else {
   clear the config file
}

How would I go about doing this? I've been trauling through Oracle documentation but have yet to find anything useful

thanks.

You can use .isSelected() to find out if the checkbox is ticked.

if (checkbox.isSelected()) {
   write login-username to config file
} else {
   clear the config file
}

Have you tried registering a listener to the "selected" property of the checkbox? It would look something like this:

yourCheckbox.selectedProperty().addListener(new ChangeListener<Boolean>() {

        @Override
        public void changed(ObservableValue<? extends Boolean> observable, Boolean oldValue, Boolean newValue) {
            // TODO Auto-generated method stub
            if(newValue){

                // your checkbox has been ticked. 
                // write login-username to config file

            }else{

                // your checkbox has been unticked. do stuff...
                // clear the config file
            }
        }
    });
