Change JToggleButton selected color

[Chris]

I would like to change the color of a selected JToggleButton (in a
ButtonGroup) to red from grey. About the only solution I can find online
is to put this in my main program:

UIManager.put("ToggleButton.select", Color.red);

However this doesn't change anything for me. Strangely if I change my
JToggleButton class to JButton this line indeed does work:

UIManager.put("Button.select", Color.red);

By the way, all my buttons are actually from a derived class called
SymbolButton that extends JToggleButton. I'm running 1.4.2 on Linux.

Thanks,
Chris

Hi Chris,

Try this, it will get you started anyhow, from some code I have here....Ike

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.border.*;

public class JTASToggleButton extends JToggleButton {
public boolean pressed;
/** Creates a new instance of JTASToggleButton */
public JTASToggleButton() {
super();
addMouseListener(new MouseAdapter(){
//the following functions not needed since this is an adapter
class:
public void mousePressed(MouseEvent Me){
pressed=!pressed;
if(pressed)
setForeground(Color.MAGENTA);
else
setForeground(Color.BLACK);
}
});
}


}

Thanks Ike. I tried adding a MouseListener to my JToggleButton class but
found that:
1. setForeground doesn't do anything, but setBackground does
2. setBackground changes the color of the non-selected buttons, not the
selected button

So I'm still looking for something to change just the color of the
selected button and nothing else.

Thanks,
Chris

class myToggleBtn extends JToggleButton {
  String s;

  public myToggleBtn(String str, Boolean sel) {
    super(str, sel);
    s = str;
  }

  public void paintComponent(Graphics g) {
    super.paintComponent(g);
    if (this.isSelected()) {
	    int w = getWidth();
	    int h = getHeight();
	    g.setColor(Color.green); // selected color
	    g.fillRect(0, 0, w, h);
	    g.setColor(Color.darkGray); // selected foreground color
	    g.drawString(s, (w - g.getFontMetrics().stringWidth(s))/2 + 1, (h + g.getFontMetrics().getAscent())/2 - 1);
	}
  }
}
