Original JOptionPane Color

[jiffi]

hi

I changed my JOptionPane dialog boxes to colors, but i can't figure out how to change them back to the original colors. Also, if someones has a list of all the possible colors that can be used, that would very much be apreciated. thanks

  Object color = " ";
            Object background = " ";
            UIManager um = new UIManager();
            color = JOptionPane.showInputDialog(null, "Choose a Color for your text", "Menu",
                JOptionPane.QUESTION_MESSAGE, null, new Object[] { "green" ,"red",
                    "orange", "blue", "black", "yellow", "white" }, "");
            if ( color == "green")
            {
                 um.put("OptionPane.messageForeground", Color.green);
            }
            if ( color =="red" )
            {
                um.put("OptionPane.messageForeground", Color.red);
            }
            if ( color == "blue")
            {
                um.put("OptionPane.messageForeground", Color.blue);
            }
            if ( color == "orange")
            {
                um.put("OptionPane.messageForeground", Color.orange);
            }
            if ( color == "yellow")
            {
                um.put("OptionPane.messageForeground", Color.yellow);
            }
            if ( color == "white" )
            {
                um.put("OptionPane.messageForeground", Color.white);
            }
            if ( color == "black")
            {
                um.put("OptionPane.messageForeground", Color.black);
            }

            background = JOptionPane.showInputDialog(null, "Choose a Color for your Background", "Menu",
                JOptionPane.QUESTION_MESSAGE, null, new Object[] { "green" ,"red",
                    "orange", "blue", "black", "yellow", "white" }, "");
            if ( background == "green")
            {
                 um.put("Panel.background", Color.green);
            }
            if ( background == "red" )
            {
                um.put("Panel.background", Color.red);
            }
            if ( background == "blue")
            {
                um.put("Panel.background", Color.blue);
            }
            if ( background == "orange")
            {
                um.put("Panel.background", Color.orange);
            }
            if ( background == "yellow")
            {
                um.put("Panel.background", Color.yellow);
            }
            if ( background == "white" )
            {
                um.put("Panel.background", Color.white);
            }
            if ( background == "black")
            {
                um.put("Panel.background", Color.black);
            }

            if ( color == "orange")

Don't try to compare Strings for equality like that; use the equals( ... ) method instead (read th API documentation for the String class). b.t.w. get the color from the object before you change it so you can restore the original color afterwards.

thanks for your links, though the first one gives me an error 404…

@Jos So basically, you want me to use if (color.equals("orange")) instead?

i'm not sure i follow- i only know basic java, if you could please elaborate, thanks

Yep, the equals method compares two Strings for equality of their content. Read the following pseudo code:

1) Color originalColor= yourObject.getColor();
2) change the color of yourObject at will ...
3) restore the original color: yourObject.setColor(originalColor);

So in my case, yourObject would be replaced by either OptionPane.messageForeground OR Panel.background??

yourObject is any object for which you want to change its color and later restore its original color.

I'm still really confused as to what i need to type for the code. (for what i tried, i get an error message: cannot find symbol - method getColor() )

I just gave you a bit of pseudo code, nothing to be copied/pasted without giving it a bit of thought ...
