Populating Swing JComboBox from Enum

Question

I would like to populate a java.swing JComboBox with values from an Enum.

e.g.

public enum Mood { HAPPY, SAD, AWESOME; }

and have these three values populate a readonly JComboBox.

Thanks!

This will return the exact name of the enum value. If you want more UI friendly names, JComboBox will use overridden toString() methods. – Mr. Wrong Apr 16 '19 at 12:33

If you don't want to (or can't) change initialization with default constructor, then you can use setModel() method:

JComboBox<Mood> comboBox = new JComboBox<>();
comboBox.setModel(new DefaultComboBoxModel<>(Mood.values()));

Note [*Type Inference for Generic Instance Creation*](http://docs.oracle.com/javase/7/docs/technotes/guides/language/type-inference-generic-instance-creation.html) and [generic model](http://docs.oracle.com/javase/7/docs/api/javax/swing/DefaultComboBoxModel.html), new in Java 7. – trashgod Feb 18 '12 at 16:15

The solution proposed by @Pierre is good. Usually you use a DefaultComboBoxModel or a ComboBoxModel or bindings to the ComboBoxModel for more complex stuff.

By default a JComboBox is not editable.

This in no way answers the question. – Mr. Wrong Apr 16 '19 at 12:43

This can also be achieved using only the default constructor and without using setModel() method:

JComboBox<Mood> comboBox_mood = new JComboBox<>();
