Changing JFrame Color

Hello ........
I Have an Application(JFrame) With several panels in its content pane at different times. I changes the background colors of all the panels say (blue). But there is an outline in gray around the frame (I suppose)
I have also used frame.setbackground(Color.blue);
But that doesnt change that color.
What can I do cause its kind of visible and doesnt look so nice when everything else is in another color.
Thanks
Shirantha.

Hi,
I found why there is no method to set the border in frame.
All other components in inherit from JComponent so they also get the
setBorder inherited.
But JFrame does not. JFrame is extended by Frame which is extended by Window. Window does not have a border or title bar and buttons.
So if I could do something so JFrame will not have a border, it might work.
But I still have no idea on this

You don't get a white frame when you run this program?import java.awt.*;
import javax.swing.*;
public class junk
     public static void main(String[] args) throws Exception
          JFrame f = new JFrame("Hello");
          f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          f.setSize(500,500);
          f.getContentPane().setBackground(Color.white);
          f.setVisible(true);

Changing background color in JTable, only changes one row at a time...

I'm trying to change the color of rows when the 5th column meets certain criteria. I think I'm very close, but I've hit a wall.
What's happening is the row will change color as intended when the text in the 5th column is "KEY WORD", but when I type "KEY WORD" in a different column it will set the first row back to the regular colors. I can easily see why it's doing this, everytime something is changed it rerenders every cell, and the listener only checks the cell that was just changed if it met the "KEY WORD" condition, so it sets every cell (including the previous row that still meets the condition) to the normal colors. I can't come up with a good approach to changing the color for ALL rows that meet the condition. Any help would be appreciated.
In this part of the CellRenderer:
        if (isSelected)
            color = Color.red;
        else
            color = Color.blue;
        if (hasFocus)
            color = Color.yellow;
        //row that meets special conditions
        if(row == specRow && col == specCol)
            color = color.white; I was thinking an approach would be to set them to their current color except for the one that meets special conditions, but the two problems with that are I can't figure out how to getColor() from the table, and I'm not sure how I would initially set the colors.
Here's the rest of the relevant code:
    public void tableChanged(TableModelEvent e)
        int firstRow = e.getFirstRow();
        int lastRow = e.getLastRow();
        int colIndex = e.getColumn();
        if(colIndex == 4)
            String value = (String)centerTable.getValueAt(firstRow, colIndex);
            // check for our special selection criteria
            if(value.equals("KEY WORD"))
                for(int j = 0; j < centerTable.getColumnCount(); j++)
                    CellRenderer renderer =
                        (CellRenderer)centerTable.getCellRenderer(firstRow, j);
                    renderer.setSpecialSelection(firstRow, j);
import javax.swing.table.*;
import javax.swing.*;
import java.awt.Component;
import java.awt.Color;
public class CellRenderer extends DefaultTableCellRenderer
    int specRow, specCol;
    public CellRenderer()
        specRow = -1;
        specCol = -1;
    public Component getTableCellRendererComponent(JTable table,
                                                   Object value,
                                                   boolean isSelected,
                                                   boolean hasFocus,
                                                   int row, int col)
        setHorizontalAlignment(JLabel.CENTER);
        Color color = Color.green;
        if (isSelected)
            color = Color.red;
        else
            color = Color.blue;
        if (hasFocus)
            color = Color.yellow;
        if(row == specRow && col == specCol)
            color = color.white;
        //setForeground(color);
        setBackground(color);
        setText((String)value);
        return this;
    public void setSpecialSelection(int row, int col)
        specRow = row;
        specCol = col;
}If I'm still stuck and more of my code is needed, I'll put together a smaller program that will isolate the problem tomorrow.

That worked perfectly for what I was trying to do, but I've run into another problem. I'd like to change the row height when the conditions are met. What I discovered is that this creates an infinite loop since the resizing triggers the renderer, which resizes the row again, etc,. What would be the proper way to do this?
Here's the modified code from the program given in the link. All I did was declare the table for the class, and modify the if so I could add the "table.setRowHeight(row, 30);" line.

How to change button colors in a loop?

I am working on a task that should imitate an elevator. I have two vertical
rows of round buttons "Up" and "Down" When a circle is selected randomly by
the program, the circle becomes yellow and the elevator moves to that
button.
Here is what I did:
1. created a class Circle where I save buttons' parameters
2. saved Circle objects in an array
3. drew the buttons depending on their parameters
4. generated a random number, matched it with an array index and assigned
the object color to yellow.
Everything is fine except that I can't figure out how to change colors of my
buttons in a loop.

hi,
am sorry, i couldn't make out what exactly the problem, but as ur subject line says...
may be the code give below will help you to change button colors in a loop..
          for(int i = 0; i < button.length; i++){
               int color1 = (int)(250*Math.random());
               int color2 = (int)(250*Math.random());
               int color3 = (int)(250*Math.random());
               Color c = new Color(color1,color2,color3);
               button[i] = new JButton("button name");
               button.addActionListener(this);
               //to check the r, g, b combination.
               //System.out.println(c);
               button[i].setBackground(c);
               button[i].setForeground(Color.white);
//adding into the panel
               panel.add(button[i]);
hope this would help you.

How to change the color of a title bar

Hello !
I try to change the color from my title bars, but I fail.
I tried to change the activeCaption value to an other colour, but that didn�t work. Currently I use a own LAF and set it with UIManager.setLookAndFeel("dpg.beans.GuiWindowsLookAndFeel");
import javax.swing.UIDefaults;
import com.sun.java.swing.plaf.windows.WindowsLookAndFeel;
public class GuiWindowsLookAndFeel extends WindowsLookAndFeel {
protected void initSystemColorDefaults(UIDefaults table) {
    String[] colors = {
       "activeCaption", "#B0171F"
     loadSystemColors(table, colors, false);
}I also used the complete stringarray from WindowsLookAndFeel and only changed that one color. Still no changes.
Any ideas ?

Trying to change the color of a single cell

hi, I am trying to change the color of a single cell when mouse moves over it, but couldn't do it. i even tried my own renderer, but it doesn't work. can anybody help ?

Here is what I am trying to do. I am displaying some data in a java JTable retrieved from a table in database. What is needed is when user moves his mouse over any cell in the third column, the cursor should change to hand cursor and possibly the background color should also change, to indicate the user that this cell is clickable. I have to show some other report when user clicks any cell in column three. The code follows as

Is their anyway to change the color of the progress bar and the string which shows the progress of the bar.

Can it is possible to change the color of JButton???

dear
when i click the JButton the GRAY color is shown because
i use the setContentAreaFilled(true); it is necessary for me
but i want to change this color how can i do
i also used the setBackGround and setForeground
but when click the GRAY is not changed how can i do this

I find this program handy:
import java.awt.*;
import java.util.*;
import javax.swing.*;
public class Listing {
    public static void main(String[] args) throws Exception {
        UIDefaults defs = UIManager.getLookAndFeelDefaults();

        for(Iterator i = defs.entrySet().iterator(); i.hasNext(); ) {
            Map.Entry entry = (Map.Entry) i.next();
            Object key = entry.getKey();
            Object value = entry.getValue();
            if (value instanceof Color)
                list.add(key);
        Collections.sort(list);
        JPanel panel = new JPanel(new GridLayout(0,1));
        for(int i=0; i<list.size(); ++i) {
            Object key = list.get(i);
            String text = key.toString();
            Color color = defs.getColor(key);
            JLabel label = new JLabel(text, new ColorIcon(color), JLabel.LEFT);
            panel.add(label);

        f.setLocationRelativeTo(null);
        f.setVisible(true);

        this.color = color;
    public int getIconWidth() {
        return ICON_WIDTH;
    public int getIconHeight() {
        return ICON_HEIGHT;
    public void paintIcon(Component c, Graphics g, int x, int y) {
        if (color != null) {
            Color old = g.getColor();
            g.setColor(color);
            g.fillRect(x, y, ICON_WIDTH, ICON_HEIGHT);
            g.setColor(old);
}I think you are referring to "Button.select". To change it for all buttons, call:
UIManager.put("Button.select", Color.YELLOW); //etc...

Change the color of text in the title bar

Hi,
I have a JFrame. I want to be able to change the color of the text in the title bar. Do any of you know how to do this ?
Please let me know.
Thanks
Sangeetha

If you are using Windows, you do it through the Control Panel tool for customizing your desktop display. If you are using some other system, I don't know. You can't do it from your Java program.

How to remove and change the color of Java cup and border

This is just an Image. You would need to create your own image and call setIconImage(Image) on your JFrame.

Can't change the color of a JButton when selected

I'm unable to change the color of a JButton with the following code:
UIManager.put("Button.select", Color.cyan);
SwingUtilities.updateComponentTreeUI(this);
This works just fine with 1.2.2 but when I use 1.3.1 the JButton turns gray instead of cyan. What changed between these versions?

Hello,
I tested the following code and it works on JDK1.3.1:
import java.awt.*;
import javax.swing.*;
public class RedButton {
public static void main(String args[]) {
JFrame frame = new JFrame("Red");
frame.setDefaultCloseOperation(
JFrame.EXIT_ON_CLOSE);
Container c = frame.getContentPane();
JButton defaultColor =
new JButton("Default Colors");
c.add(defaultColor, BorderLayout.NORTH);
UIManager.put("Button.background",
Color.RED);
JButton red =
new JButton("Red");
c.add(red, BorderLayout.SOUTH);
frame.setSize(200, 100);
frame.show();
You also can use one of the following properties, instead of background:
Button.background
Button.border
Button.darkShadow
Button.focusInputMap
Buton.font
Button.foreground
Button.highlight
Button.light
Button.margin
Button.shadow
Button.textIconGap
Button.textShiftOffset
So, as you can see, there is no select Option.
