Can you toggle between look and feel, want to make different "themes"

[ryuzog]

Can you?

Or is there some other way to change "themes".


if not, can anyone help with a lamer "theme"?

In my GUI I have a method called: theme3()

that basically uses a loop to change my button backgrounds.

public static void theme3(){
		for (int a = 0; a < 9; a++){
			for (int b = 0; b < 9; b++){
				Grid[a][b].setBackground(Color.ORANGE);
			}
		}
	}

final JRadioButtonMenuItem three = new JRadioButtonMenuItem("Theme: Third");
	    three.setSelected(true);
	    three.addActionListener(new ActionListener(){
	    	public void actionPerformed(ActionEvent e){
	    		theme3();
	    	}
	    });

the radio button is in "MenuBar" that extends JMenuBar that is a inner class in my GUI.

whether I type theme3(); or GUI.theme3(); there isn't any error, the thing is, clicking the button doesn't do anything either.

Try calling repaint() on each element after you change its background.

[ryuzog]

no point, tried it anyway.

when you use setText or setBackground, the button automatically changes, there should be no reason to repaint.

hear stuff about invalidate and validate, but those aren't working either

Hmm, setBackground() works for me...

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

    public class themeChange extends JFrame
      {
      JButton button;
      Color[] themes = {Color.black,
                        Color.blue, 
                        Color.cyan,
                        Color.darkGray, 
                        Color.gray, 
                        Color.green, 
                        Color.lightGray, 
                        Color.magenta, 
                        Color.orange, 
                        Color.pink, 
                        Color.red, 
                        Color.white, 
                        Color.yellow};
       public themeChange()
         {
         
         button = new JButton("Change Theme");
         button.addActionListener(
                               new ActionListener(){
                                 int i = 0;
                                  public void actionPerformed(ActionEvent e){
                                    button.setBackground(themes[i]);
                                    i++;
                                    i=i%13;
                                    }
                                 });
         
         add(button);
         }
         
       public static void main(String args[])
         {
         themeChange frame = new themeChange();
         frame.setSize(500, 500);
         frame.setVisible(true);
         }
      }

Maybe it is because theme3() is static

[ryuzog]

yeah!

some of the little things in programming are so frustrating...

sometimes I end up finding the answer by sheer luck...
I had to make it an inner class though, so the code seems too long to me =/ But I guess that's inevitable since they're so.."related" =/

What about setting Look and Feel, does that have some sort of system stuff that makes it complicated? For example multiple look and feel's at the same time aren't supported. etc...
