Java – hide jcombox box arrow

Can I hide it JCombo@R_773_2419 @Arrows shown in

I tried setting:

combo.getComponent(0).setSize(new Dimension(1,1));

But it doesn't seem to work

Solution

You must create a new combo box UI for this:

combo.setUI(new BasicCombo@R_773_2419@UI() {
    protected JButton createArrowButton() {
        return new JButton() {
            public int getWidth() {
                return 0;
            }
        };
    }
});

But be careful to inherit from the basic UI to match your current appearance

For example, if you use substance, you should SubstanceCombo@R_773_2419 @UI instead of BasicCombo@R_773_2419 @UI derivation new UI Otherwise, you may lose the functions currently provided by L & F

Editor: if you want to get some kind of autocomplete function, you'd better stick to the ordinary jtextfield and use the autocompletedecorator of swingx
