How do you set an image into the background of a JPanel or JFrame?
How do you set an image into the background of a JPanel or JFrame?
Something like this, Ive thrown in an ImageIcon on a
button too for good measure.
import java.awt.*;
import javax.swing.*;
public class JFrameImage extends JFrame {
public JFrameImage() {
Container c = getContentPane();
JPanel panel = new JPanel(){
public void paintComponent(Graphics g) {
ImageIcon img = new
= new ImageIcon("background.jpg");
g.drawImage(img.getImage(), 0, 0, null);
super.paintComponent(g);
panel.setOpaque(false);
ImageIcon icon = new ImageIcon("onButton.jpg");
JButton button = new JButton(icon);
panel.add(button);
c.add(panel);
public static void main(String[] args) {
JFrameImage frame = new JFrameImage();
frame.setSize(200,200);
frame.setVisible(true);
Going totally fancy pants
ImageIcon bigImage = new ImageIcon(bgImage.getImage().getScaledInstance(getWidth(), getHeight(),Image.SCALE_REPLICATE));
g.drawImage(bigImage.getImage(), 0, 0, this); Will scale the image to the size of the panel
whereas
for (int y = 0; y < getHeight(); y = y + image.getHeight(null))
for (int x = 0; x< getWidth(); x = x + image.getWidth(null))
g.drawImage(image, x, y, this); Will give a tiled effect
Try tiling with an animated gif and bring your processor to a standstill. -

How to make a JPanel selectable
When extending a JPanel and overriding the paintComponent() method the custom JPanel can not be selected so that it gets for example KeyEvents.
But if I make the new Class extend a JButton it gets of course selected and able to receive for example KeyEvents.
My question is therefore; what does the JButton implement that a JPanel doesn’t so that a JButton gets selectable? Or in other words; how to make a JPanel selectable?
Aleksander.Try this extended code. Only the first panel added can get the Focus.

How to place a JPanel at the center of another JPanel?
Can anyone tell me how to place a JPanel inside another JPanel? The first JPanel consists of three JPanels each consisting of a label&textfield and are placed using BoxLayout. The second JPanel is a big blank screen. So, i would like to put the first JPanel at the center of second JPanel(horizontally & vertically). The problem is that i don't have any other component. So,if i try to use FlowLayout, i am able to put it at the center(horizontally, not vertically) only on the top edge. I tried to use BoxLayout. But, i couldn't(as i don't have any other elements). I tried to create some blank elements. But, they are messing up the elements of my JPanel. Any cluesssssssss??????????

Title: How to give transparency effect to JFrame?
Hai,
we are developing stand alone application using java swing. In our application we need to show an image in JFrame. We draw an image in JPanel using JPanel's paintComponent method. Then we place this JPanel into JFrame. The image is having transparent effect. But we are not able to give transparency effect to JFrame so we couldn't see desktop we are seeing only JFrame's background. *{color:#0000ff}How to give transparency effect to JFrame?*
*{color}*
Thanks for your help.It's not a commited part of the standard API yet, but as of 1.6_10 you can add transparency effects to a window through the use of
com.sun.awt.AWTUtilitiesI think this was the original article on the release. If you google, you will find many creative ideas that people have come up with using this particular feature. -
Beginners Questions about Multiple JPanels in JFrame and event handling
I am a newbie with SWING, and even a newerbie in Event Handling. So here goes.
I am writing a maze program. I am placing a maze JPanel (MazePanel) at the center of a JFrame, and a JPanel of buttons (ButtonPanel) on the SOUTH pane. I want the buttons to be able to re-randomize the maze, solve the maze, and also ouput statistics (for percolation theory purposes). I have the backbone all done already, I am just creating the GUI now. I am just figuring out EventHandlers and such through the tutorials, but I have a question. I am adding an ActionListener to the buttons which are on the ButtonPanel which are on JFrame (SOUTH) Panel. But who do I make the ActionListener--Basically the one doing the work when the button is pressed. Do I make the JFrame the ActionListener or the MazePanel the ActionListener. I need something which has access to the maze data (the backbone), and which can call the Maze.randomize() function. I'm trying to make a good design and not just slop too.
Also I was wondering if I do this
JButton.addActionListener(MazePanel), and lets say public MazePanel implments ActionListenerdoesn't adding this whole big object to another object (namely the button actionlistener) seem really inefficient? And how does something that is nested in a JPanel on JFrame x get information from something nested in another JPanel on a JFrame x.
Basically how is the Buttons going to talk to the maze when the maze is so far away?I'm not an expert, but here's what I'd do....
You already have your business logic (the Maze classes), you said. I'm assuming you have some kind of public interface to this business logic. I would create a new class like "MazeGui" that extends JFrame, and then create the GUI using this class. Add buttons and panels as needed to get it to look the way you want. Then for each button that does a specific thing, add an anonymous ActionListener class to it and put whatever code you need inside the ActionListener that accesses the business logic classes and does what it needs to.
This is the idea, though my code is totally unchecked and won't compile:
import deadseasquirrels.mazestuff.*;
public class MazeGui extends JFrame {
JPanel buttonPanel = new JPanel();
JPanel mazePanel = new JPanel();
JButton randomizeB = new JButton();
JButton solveB = new JButton();
JButton statsB = new JButton();
// create instanc(es) of your Maze business logic class(es)
myMaze = new MazeClass();
// add the components to the MazeGui content pane
Component cp = getContentPane();
cp.add(); // this doesn't do anything, but in your code you'd add
// all of your components to the MazeGui's contentpane
randomizeB.addActionListener(new ActionListener {
void actionPerformed() {
Maze newMaze = myMaze.getRandomMazeLayout();
mazePanel.setContents(newMaze); // this is not a real method!
// it's just to give you the idea
// of how to manipulate the JPanel
// representing your Maze diagram,
// you will probably be changing a
// subcomponent of the JPanel
solveB.addActionListener(new ActionListener {
void actionPerformed() {
Solution mySolution = myMaze.getSolution();
mazePanel.setContents(mySolution); // again, this is not a real
// method but it shows you how
// the ActionListener can
// access your GUI
// repeat with any other buttons you need
public static void main(String[] args) {
MazeGui mg = new MazeGui();
mg.setVisible(true);
// etc...

How to place an image in JFrame
hello
i want to know how to place a image on JFrame
i am not using any layout..
pls help..Hi...
To do this, u can look to tweak the paintComponent() method . All u have to do is create a JPanel subclass and override the paintComponent method to draw the image. then set it as the frame's content pane. that is because you work only on the content pane in swing. that should help.
Source for ImagePanel :
<code>
package com.rsramanujam.help;
import javax.swing.*;
import java.awt.*;
import java.awt.image.*;
public class ImagePanel extends JPanel
Image backImage = null;
public ImagePanel(Image backImage)
try
this.backImage = backImage;
catch(Exception e)
System.out.println("Could not get Image");
public void paintComponent(Graphics g)
Graphics innerG = g.create();
if(backImage == null)
innerG.setColor(new Color(0xffccccff));
innerG.fill3DRect(0,0,getSize().width,getSize().height,true);
else
innerG.drawImage(backImage,0,0,getSize().width,getSize().height,this);
public void setBackImage(String path)
ImageIcon ic = new ImageIcon(path);
this.backImage = ic.getImage();
repaint();
</code>
U can see a working example at http://www.geocities.com/ramanujam_off/java.
There , download the app called RamHelp. It comes with a GUI that uses panels with Background Images.
