java swing radio buttons with vertical text
Question
Trying to get radio buttons that look like this in java with swing:
* * *
O A O
F U N
F T
O
...where the * is the radio button
The letters can either be right side up or on their side, I don't really care. I just want the buttons at the top and the letters below each button in a narrow column.
Tried rotating with graphics in the paint() method but it messes up when I mouse over it, redrawing the buttons without rotation. Seems what I need is something like BoxLayout but that will also rotate by 90 deg. Or maybe another layer between the JPanel and the buttons.
public class OffAutoOn extends JPanel {
public OffAutoOn ()
{
JRadioButton b1 = new JRadioButton ("OFF");
JRadioButton b2 = new JRadioButton ("AUTO");
JRadioButton b3 = new JRadioButton ("ON");
ButtonGroup bg = new ButtonGroup ();
bg.add (b1);
bg.add (b2);
bg.add (b3);
setLayout (new BoxLayout (this, BoxLayout.Y_AXIS));
add (b1);
add (b2);
add (b3);
}
@Override
public void paint (Graphics g)
{
Graphics2D g2d = (Graphics2D) g;
AffineTransform at = g2d.getTransform ();
try {
int w = getWidth ();
int h = getHeight ();
g2d.rotate (Math.PI / 2, w / 2, h / 2);
super.paint (g);
} finally {
g2d.setTransform (at);
}
}
}

You can use HTML to create vertical text for the button and then you can change the default position of the text relative to the icon.
For example:
String text = "<html>A<br>u<br>t<br>o</html";
JRadioButton button = new JRadioButton( text );
button.setHorizontalTextPosition(JRadioButton.CENTER);
button.setVerticalTextPosition(JRadioButton.BOTTOM);
