IMAGEICON help
anybody know how to set image icon as a background to put inside a panel..ANybody could give help
do not know but maybe this might help yuo can overide the panels paintComponent( Graphics g) method allowing to draw an image every time the componenet is painted. It could serve as a background image? Done like so. Remember to keep the super.paintComponent(g) its important.
public void paintComponent (Graphics g)
super.paintComponent(g);
g.drawImage(img,0,0,this);

Hi,
I have a JTree that uses a cell renderer, and the cell renderer reads an Image.gif .
However, when I run the appletm I get a this:
java.security.AccessControlException: access denied (java.io.FilePermission menu_tee_minus.gif read)
Please help!
SangitaSangita --
It sounds like the image file is just being opened
as a regular file -- maybe something in your
directory?
Applets are not normally allowed to open files or
run programs on the local machine (to prevent damage
to the local machine by a malicious applet).
One thing you can do is put the image file in the same
directory as the applet class file (or a subdirectory
of that directory) and use a URL to refer to it.
There's an example here:
java.sun.com/docs/books/tutorial/uiswing/components/applet.html#images
And more info here:
java.sun.com/docs/books/tutorial/uiswing/misc/icon.html
especially the section on "Specifying the Image Source"
and the bit about jar files just above.
With the image file in the same directory as your
applet class file, you might do something like:
URL baseURL = getCodeBase();
ImageIcon img = new ImageIcon(getURL(baseURL, "Image.gif"));
Another thing you can do is supply the image and the
applet together in a jar file -- then both get read
from the server in the same operation. Use the same code as above in the applet, but in the applet tag in
the web page, include an "archive" option that points
to the jar file. E.g.
<applet code="YourApplet.class"
archive="YourAppletBundle.jar">
plus whatever other options you need. The archive
can be a URL or a path instead of just a file name.
There's more on the applet tag at:
www.w3.org/TR/REC-html40/struct/objects.html
They say the applet tag is obsolete, and we should use
"object" instead ;-).

Imageicon help need, please!!!!
Hi,
I want to make a simple java Slide show program. I have 24 images and I was wondering how (EASILY or Automatically) to make an imageIcon object for each one, insteastead of declaring individual objects one by one. Here is how I know it, but I don't like it.
ImageIcon slide0 = new ImageIcon("images/slide0.jpg");
Image image0 = slide0.getImage();
ImageIcon slide1 = new ImageIcon("images/slide1.jpg");
Image image1 = slide1.getImage();
ImageIcon slide2 = new ImageIcon("images/slide2.jpg");
Image image2 = slide2.getImage();
ImageIcon slide24 = new ImageIcon("images/slide24.jpg");
Image image24 = slide24.getImage();So, how do i do this (maybe an array of ImageIcon), but how do I deal with the file names?
Thank for any helpful input.
Peace.I see one of two ways to do this fairly easily. If the File names are all different then you could have an array of Strings that represents the file name. If they all have a common path, then perhaps you could use a String constant that represents the path and just concatenate the two in your loop.
Your current situation however lends itself well to simply having a String constant for your path and for your partial file name (without the extension) and then just add the numeric part to the file name and the extension by String concatenation within the loop. You should be able to figure this out, I'll bet. Good luck. -

Hi all, I am currently writing a program which should allow me to add, delete, search and edit database records. What i would like to do is to click one of the six buttons on the toolbar and it to lauch a form within an internal frame. I have had a go but a cannot make the frame viewable.

What went wrong? (swing-mdi-screen resolution)
Hello,
I have completed my java application which I relied heavily on swing components and awt lay out managers. It is an MDI and I had developed it using border/flow/grid layout managers under a 1024*768 resolution.
Today I ran it on a different machine that has 800*600 resolution and I was very sorry to see that the JFrame components such as buttons, textboxes don't fit in one window.(You just cant see some of the components) Did I do something wrong that caused this problem? Otherwise is this expected behaviour? However the main window's size fits the screen size. So the components should have displayed smaller to fit in the screen, but that is not the case now. What to do now?
I appreciate your help&feedback on this.
metinThanks KPSeal,
Here is the method that builds one of the JInternalFrame's. It may be abit confusing since it is complex. Unfortunately I won't have time to fix it since I have to return the project today. Better not to tell about the resolution issue to my professor ;) This method is a small fraction of my thesis. Looks just fine with 1024*768. Very very bad with 800*600

Any help would be greatly appreciated.There are many different ways to layout your window, but here's a couple thoughts.
Use a BorderLayout for the main content pane. Add your large icon label to the NORTH of the content pane. Then create 2 subpanels - one for the CENTER where the two text labels will go, then one for the SOUTH for the buttons.
For the center subpanel, I would probably use a vertical BoxLayout or maybe a Gridlayout in order to get the two text labels on two separate 'lines'.
For the button panel, it looks like you desire 2 rows of buttons, so you will need 2 subpanels within the main button panel. I would use BoxLayout for each of the subpanels. Because you used a GridLayout, all of your buttons are sized to be the same size as the largest of the buttons, which causes it to be too wide. BoxLayout will let each button go to its preferred size, which should make it smaller and more likely to fit. You will need to use the Box.createHorizontalGlue and Box.createHorizontalStrut methods to space your buttons.
You could also throw away all the nested panels, and just use a single panel with a GridBagLayout. GridBagLayout is very powerful, but often confusing and frustrating for first time users, so I'd recommended sticking with the nested panel approach you started with, just use some different layout managers. -
Need help importing animated gif by ImageIcon in Japplet
Hello. Im new to Java, but I want to import this animated gif with Java in a Japplet using ImageIcon, but it does not work and I would really appreciate if anyone could help me with this.
import java.applet.*;
import java.awt.*;
import java.net.*;
public class Bilder extends Japplet{
public ImageIcon(java.net."http://pixelninja.se/kappawin.gif");
Image[] bild = new Image[1];
int nr=0;
public void init(){
setBackground(Color.black);
bild[0] = getImage(getCodeBase(),"4a.gif");
public void paint(Graphics g){
g.drawImage(bild[0],50,50,212,282,this);
}You cant do animated gifs this way.
Also you should remember that you cannot load images in to an applet if it is hosted somewere else than the host that hosts the applet.
Esiast way to display an image icon with a animated gif will be creating a Image Label and adding it to the applet.
Ex:-
public class MyImageApplet extends JApplet{
public void init(){
getConentPane().setLayout(new BorderLayout());
URL imageURL = getClass().getResource("/myImage.gif");
// Above image file should be in the code base or in the archive file of the applet
getConentPane().add(new JLabel(new ImageIcon(imageURL)));
} -
First, I'm using 1.4 on Windows NT. Periodically the
ImageIcons on my toolbar buttons disappear. Most of
the time everything is fine, but sometimes the images
just disappear. If I drag another window over my toolbar,
the images get redrawn most of the time, but its not
a guarantee. From what I have seen on this Forum, other
folks have also encountered this problem, but I have
yet to hear of a solution other than to ignore it. If anyone
has any kind of solution, I would appreciate hearing from
you.As a workaround you can set the following property when you run your java program:
-Dsun.java2d.noddraw=true
This is a known bug (4664818).
Hope that helps... -
Help please with a Static Initializer for ImageIcons inside Jar Files
At the moment I'm playing around displaying XML using A JTree
I am subclassing DefaultMutableTreeNode, and want it to have some default Icons set up....
Sort of like this:
public class XNode extends DefaultMutableTreeNode
public static final ImageIcon icon;
public static ImageIcon getIcon()
return XNode.icon;
}The only thing is that for the life of me after trying various things and searching these forums and google:
I can't work out how to write the static Initializer for the ImageIcon.
The ImageIcon will need to be created using a URL, cos it will be inside my jar file.....
the usual...
URL url = this.getClass().getResource("/images/Exit16.gif");
ImageIcon Icon = new ImageIcon( url );but I wanted these Icons to be class members..............
Could someone help?
}DrClap " I don't understand why you put Class.forName in there either"
A: Because I don't really know what I'm doing.
I will try that suggestion.
At present I have this:
static ImageIcon loadIcon;
static
try
loadIcon = new ImageIcon( Class.forName("cis.editor.xml.nodes.AlNode").getResource("/images/Exit16.gif"));
catch( ClassNotFoundException cnfe )
System.out.println("ClassNotFound: " + cnfe.getMessage() );
public static final ImageIcon defaultIcon = loadIcon;
static
try
loadIcon = new ImageIcon( Class.forName("cis.editor.xml.nodes.AlNode").getResource("/images/tree_folder_major.gif"));
catch( ClassNotFoundException cnfe )
System.out.println("ClassNotFound: " + cnfe.getMessage() );
public static final ImageIcon commentIcon = loadIcon;
//.......... ANd so OnWhy? Because do far it was the only way I could get it to compile.
And It works..
However it's a real abortion.. codewise.
I need to load about 16 Icons that the various subclasses can 'use'
DefaultTreeCellRenderer - must do somethng similar because it has a bunch of Icons to "Pick from",
Only How is that done 'properly' ? -
ImageIcons... JPanels.... JLabels... help?
Hello all.
I am a noobie at this stuff (just to let y'all kno) and I'm having a hard time drawing/painting an ImageIcon on a JPanel. I'm not really sure, but I think it has something to do with the fact that the Graphics class is abstract (so obviously I can't make an instance of it) and therefore I can't pass a graphics object in a parameter without getting a NullPointerException or compiler error saying "g" has not been initialised.
here's part of the code:
ImageIcon image = new ImageIcon("C:\\marble.JPEG", "a marble");
JLabel background = new JLabel(image);
container.add(background, BorderLayout.CENTER);
Any help would be greatly appreciated. :-)the method you need is
setIcon()
here's the earlier code, modified for the image to show after clicking the button
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class Testing extends JFrame
public Testing()
setSize(600,400);//needs a size, otherwise frame will be very small (label is empty)
setLocation(300,100);
setDefaultCloseOperation(EXIT_ON_CLOSE);
JPanel p = new JPanel();
final JLabel lbl = new JLabel();
p.add(lbl);
getContentPane().add(p,BorderLayout.CENTER);
JButton btn = new JButton("Show Image");
getContentPane().add(btn,BorderLayout.SOUTH);
btn.addActionListener(new ActionListener(){
