Is there a way to change the JComboBox's items focus?

Question

I can change the item's focus by pressing the arrow keys on the keyboard or by moving the mouse over it. Is there a programmatic way to move the focus around the items?

Answer 1

You can simply set the selected item. Optionally, you can show the dropdown list:

comboBox.requestFocus();
comboBox.showPopup();
comboBox.setSelectedIndex(selectedIndex);
