Question

I have a JComboBox that its renderer is a JLabel with an Icon for each item in the combo list :

class ComboBoxRenderer extends JLabel implements ListCellRenderer {
    public Component getListCellRendererComponent(
                JList list,
                Object comboItemObject,
                int comboItemIndex,
                boolean isSelected,
                boolean cellHasFocus) {
        String comboItemTitle = (String)comboItemObject;
        setText( comboItemTitle );
        setIcon( new ImageIcon( getClass().getResource( "/images/myIcon.png" ) ) );

        return this;
    }
}

When i select an item from the comboBox i just want to show the selected item text in the comboBox, and not the item icon also. Is there a way i can do that ?

Answer 1

In the rendering code you can check the index. Something like:

if (index == -1)
{
    setText(...);
}
else
{
    setText(...);
    setIcon(...);
}

Also, you should not be reading the image in the rendering code since code is called frequently.
