How do I populate a JavaFX ChoiceBox with data from the Database?

Question

private void initialize() {
    loadPersistenceContext();

    List events = getEventsChoiceBox(getPersistenceContext());
    ObservableList

        

Answer 1

Here is another simple implementation from forums.oracle.com

Create a class for key - value

public class KeyValuePair {
   private final String key;
   private final String value;
   public KeyValuePair(String key, String value) {
   this.key = key;
   this.value = value;
   }

  public String getKey()   {    return key;    }

  public String toString() {    return value;  }
}

Then create the ChoiceBox as:

ChoiceBox choiceBox = new ChoiceBox();

Fill the elements as;

choiceBox .getItems().add(new KeyValuePair("1", "Active"));

Hint: Retrive key-value pair from you database into an ArrayList and iterate

To retrieve the value:

choiceBox.getValue().getKey();  // returns the "1"
choiceBox.getValue().toString();  // returns the "Active"
