I was wondering if you could help me!!
Thank you so much

It looks like you're trying to read your icons from the local disk--that's a no-no for (unsigned) applets.
Change your applet to fetch the icons from the same host from which the applet comes.

How do you make an array of image icons and then call them?

How do you make an array of image icons and then call them, i have searched all over the internet for making an array of icons, but i have
found nothing. Below is my attempt at making an array of icons, but i cant seem to make it work. Basically, i want the image to match the value of the roll of the dice (rollVal)
Any help would be greatly appreciated, some code or link to tuturial, ect.
/** DiceRoller.java
* Roll, print, Gui
import javax.swing.*;
public class DiceRoller extends JFrame
     private ImageIcon[] image ;
     public String[] images = { "empty", "dice1.jpg",

     if (image!=null){
          j1.setIcon(image[rollVal]);
     System.out.println("Roll = "+die.roll());

Heavyweight object of an Icon and JLabel

Hi there,
I would like to know how can I create a heavyweight object that has a JLabel and an Icon and then add it to a JFrame. this heavyweight object would be something like this
public class TestObject extends JPanel
..public TestObject( String LabelName )
....theLabel = new JLabel( LabelName );
....add( theIcon ); // I cant add the Icon here, because it's not a Component
....add( theLabel );
..private JLabel theLabel;
..private Icon theIcon = new ImageIcon( "littleIcon.gif" );
Thanks,
Andre

Using the following class I could draw a JLabel that has an ImageIcon, but it doesn't matter what the value of the horizontalAlignment ( LEFT, CENTER, RIGHT, LEADING or TRAILING ) the icon was always at the left side and the string at the right. Is there a way to put the Icon on the top and the String at the button of the Label?
public class TestObject extends JPanel
public TestObjectent( String LabelName )
theIcon = new ImageIcon( "littleIcon.gif" );
theLabel = new JLabel( LabelName theIcon, SwingConstants.TRAILING );
add( theLabel );
private Icon theIcon;
private JLabel theLabel;
Thanks,
Andre

Gnome applet Icons Missing

I installed a fresh arch linux on another pc. I installed gnome and gnome-extras. There is one problem:
The icons on the "system tray" are missing. The applets are there but the icons are not shown:
I already rebuilt the hicolor and gnome icons (and re-logged) with no result. Am I missing something?

Ok here is something weird I found out.
I am using xorg without xorg.conf. Since I have a Voodoo3 card I installed the xf86-video-tdfx driver. After a xorg restart the icons are working but the mouse flickers when I move it and there are graphic bugs when restoring windows.
So I removed the tdfx driver and reverted to the vesa driver. The mouse does not flicker anymore but the applet icons are gone.

Admin Applet icons not visible

Hi Guys,
I have installed UCM on server with apache as web server and java 1.5.
UCM installed successfully..but what i found is admin applet icons are visible if i open my content server from local system but when i use server system IP and try to open UCM from remote desktop admin applet icon are not visible.
Is this java version error. How can i resolve it?
Thanks & Regards,
Sunil

Hi Sunil,
I might sound like I'm repeating but you said you have Java 1.5 on your desktop which is fine cause you can see it from there but.. do you have 1.5 for the <u>browser you're using in the remote desktop</u>? Because this is surely a browser JRE issue.
Go to the browser properties and look for the JRE your browser is using:
i.e IE explorer: Internet Options->Advanced Tab-> scroll down until you find the Java option and make sure JRE 1.5 (or later) is being used.
Let us know

JLabel Icon and Text

Hi,
I am creating a JLabel and setting an ICon with setIcon method. The label has a square border and a text. The Icon covers the the label with "X" form corner to corner on the square border. I can't see the text after setting the Icon. I tried to set the text after Icon, still it is hidden.
So what should I do to display the Icon and Text at the same time and want the text to be visible.
thanks,
NT

public static void main(String[] args)
JFrame jf = new JFrame();
jf.setSize(500, 250);
JPanel jp = new JPanel();
jp.setSize(250, 250);
jp.setLayout(null);
ImageIcon im = new ImageIcon("4.gif");
JLabel jl = new JLabel();
jl.setOpaque(true);
jl.setBounds(0, 0, 150, 16);
jl.setBorder(new LineBorder(Color.BLACK));
jl.setText("NAME");
jl.setIcon(im);
jp.add(jl);
jf.add(jp);
jf.setVisible(true);
this sets the icon and the text, but the icon is first and then the text. I want the icon on top of Text.
thanks,
NT

Asking about icon and mouselistener

i think i post this thread before but it was gone. so i post it again.
anybody knows how to insert icon in JFrame? so far, it can only implemented in JPanel. and somebody help me how to make icon larger than before and show some tooltip when mouse select it? in my mind, we just add listener when mouse over image, then setTooltips. is it right?

i think i post this thread before but it was gone. so i post it again. Quit cluttering the forum with multiple postings and learn how to use the forum properly.
You can find you postings by:
a) displaying your "Watch List" which can be found on the left of the forum when you are logged in
b) searching the forum for any posting that contains your userid
Also, Swing related questions should be posted in the Swing forum, but there is no need to create a third posting because you already got an answer in your first posting so all you need to do is find it.

Lost SMS Icon and get error message Uncaught exception Index 20 = 20

Dear All
I have lost my SMS Icon and looking at previous forums have carried out the following techniques which do not work
1. I have gone to Messages - Options - SmS & Email Inboxes - Seperate but this does not solve anything
Within this step i have switched off phone taken out battery etc...
2. I have gone to Applications - menu - "show all" but my SMS icon cannot be found
Just to note even when i go to Messages - View Folder - SMS Inbox .....i get the error message again
Uncaught exception Index 20 > = 20
Anyone able to help ? Would be greatly appreciated.
Thanks

You may have already figured out your fix - but yesterday I went thru the same thing with my son's phone. Overnight he lost his SMS & MMS Icon and was receiving Uncaught Exception Index 28 >= 28. I called Verizon Tech Support and was told there was a corrupt file in the calendar.
We backed up the phone using the Desktop Manager - performed a security wipe and restored his phone.
His phone is back up and running as it should be. Hope this helps.

Next time you accidentally use 3 fingers it will zoom again. Unless you need the feature you're better to turn it off

I have installed Adobe Premiere Pro cc on my laptop, but I cant find a way to start the program. No Icon, and it is not showing up in the start meny. It is showing up in add/remove programs, but nt anywhere else.

If you are using a Mac, simply hit Command-Spacebar to bring up Spotlight Search. Begin typing the name of the application and when you see what you are looking for, press enter. You should get a hit by the second or third letter you type. Great way to launch apps on computers that you are not familiar with.
Windows 7 and 8 should have something similar. I think you simply press the Windows key and begin typing. Press enter when you see a match.
Both Mac and Windows search tools can be customized to search for applications, files, emails and so forth. For Windows, look for Taskbar and Start Menu Properties. For Mac, go to Preferences Spotlight. Turn off items you know you won't need to speed up searches.

Photoshop CC icons and text are too small: how to adjust so they're readable? [was: Joanne]

I have just downloaded Creative Cloud on a new computer. The new photoshop icons and text are too small for me to see or work with. I cannot seem to adjust this so its "useable"

Hey Bob,
Ive put feature requests for this in before and I know many others have as well. Is there any way to see if Adobe is actually working on this? I dont really consider this a feature request, it should be standard with the software. A feature request would be something like creative cloud libraries, not the ability to make font sizes and icons bigger.
