Z-value on imageicon/jlabel
Hi wonder how to put a z-value on a imageicon or jlabel? (which to be on top, and second..etc)
Thanks in advance!
Swing related questions should be posted in the Swing forum.
Use a [url http://java.sun.com/docs/books/tutorial/uiswing/layout/visual.html]Card Layout or a [url http://java.sun.com/docs/books/tutorial/uiswing/components/layeredpane.html]LayeredPane.

Hi. I have created a jLabel that get's it's Icon updated via a value derived from a MYSQL query. The Icon1 value is a URL. My question is, if I do the MYSQL query and the URL doesn't change from the existing value, does the jLabel still go out and pull the image over? Or does it recognize that the URL is still the same and doesn't make an attempt at pulling the image over? Basically, I am asking this because I'm trying to determine the load on my webserver. Thank you for your help!
image1.setIcon(icon1);Hi Daryl. Here is what I'm doing:
protected static ImageIcon createImageIcon(String URL,
String description) {
//java.net.URL imgURL = LabelDemo.class.getResource(URL);
java.net.URL imgURL = null;
try {
imgURL = new java.net.URL(URL);
} catch (Exception e) {
//Logger.getLogger(LabelDemo.class.getName()).log(Level.SEVERE, null, ex);
if (imgURL != null) {
return new ImageIcon(imgURL, description);
} else {
System.err.println("Couldn't find file: " + URL);
return null;
ImageIcon icon1 = createImageIcon("https://www.website.com/images/" + dateVal + "/thumbs/" + image2Val + "",
image1.setIcon(icon1); -
Displaying JList holding JLabel with icons of different height screwed up
I started to create a unix 'make' wrapper, which filters for the binaries being created and display their names and potentially some icon for those in a JList.
But sometimes the display of the icons is screwed up. It's cut to the size of a pure text (JLabel) line in the JList.
Below you can find test program.
You need to put two different sized picture files binary1.jpg and binary2.jpg in the run directory of the java build (i use eclipse)
and create some test input file like this:
> cat input
binary1
binary2
binary3
binary4
binary5
binary6
binary7
binary8
binary9
Set TEST_DIR environment variable to the build run directory.
Finally start the java class like this:
> bash -c 'while read line; do echo $line; sleep 1; done' < input| (cd $TEST_DIR; java -classpath $TEST_DIR myTest.MyTest)
Then you should see the issue.
( Don't mind about the JAVA code in general - i know, that there are quite some other issues to fix :-) )
- many thanks!
best regards,
Frank

Hello,
Can I have JList with an ImageIcon beside it?e.g
"imageicon" "sometext"
code snippet would be helpful.
ThanksHello,
little improvement-update, custom ListCellRenderer now checks whether object is a String only or a JLabel with an ImageImage. You can use it for both versions of JLists.
import javax.swing.*;
import java.awt.*;
public class ImageTextList extends JFrame
private static String[]text = new String[10];
private static JLabel[]labels = new JLabel[text.length];
private static ImageIcon[] icons = new ImageIcon[labels.length];
static
for(int i=0; i<text.length; i++)
text[i] = "Images " + (i+1);
icons[i] = new ImageIcon( "../testproject/img/" + (i+1) + ".jpg");
labels[i] = new JLabel(text, icons[i], JLabel.CENTER);
public static void main(String[] args)
new ImageTextList();
public ImageTextList()
super("Image+Text in a JList");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//test with labels and text
JList list = new JList(labels);
list.setCellRenderer(new MyCellRenderer());
getContentPane().add(new JScrollPane(list));
pack();
setLocationRelativeTo(null);
setVisible(true);
class MyCellRenderer extends JLabel implements ListCellRenderer
private JLabel label = null;
// This is the only method defined by ListCellRenderer.
// We just reconfigure the JLabel each time we're called.
public Component getListCellRendererComponent(
JList list,
Object value,
// value to display
int index, // cell index
boolean isSelected, // is the cell selected
boolean cellHasFocus) // the list and the cell have the focus
String s = value.toString();
ImageIcon icon = null;
//checks whether the source is a label or another object(String only)

Touble getting cell values from jTable
Hi everybody, I need some hepl to understand this problem.
I have jtable and I�m trying to get the values from the cells (first in the jOption panel then to jLabel and to jTextFields).
All cell values are shown perfectly in the JOptionPanel.
But I can�t get any values to the jLabel from the first column(0) no matter what row I press from the firts column.
It gives me this error
Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException: java.lang.Integer
at taulukko3.FTaulukko3.jTable1_mouseClicked(FTaulukko3.java:163)Here is my code where I think the problem is:

try{
int valittusarake = jTable1.getSelectedColumn();
String tulos= "";

I got it workin by making this change to my code:

Object tulos1 = jTable1.getValueAt(jTable1.getSelectedRow(),jTable1.getSelectedColumn());

Cannot display JLabel text in JTable
Hi, This is a simple but frustrating little problem
I am having trouble displaying the label text in a column of a JTable.
I have hacked up a copy of TableDialogEditDemo.java from the tutorials
on using JTables. This uses a renderer and editor models to deal with a
column of colors.
I have changed it to use JLabels instead. What want is for the label
text to appear and when the user selects the cell be allowed to launch
a dialog box (such as the demo program does with colorchooser).
The dialog launching funcionalty works fine but the label text does not display.
I end up with the column of JLabels as blank, even though the values
are properly set. It seems like the TableCellRenderer doesn't display the
controls text.
I've spent the better part of two work days trying to get this one to work.
Compiling and just running the code (without any interaction with the table)
shows the problem. The second column of items will be blank instead of
cells with text.
Help!
Thanks!

Just didn't realize I needed to set the text of the component but with your

Actually I needed to use:
setText(t_label.getText());
Using toString got me: "java.swing......" (the components text representation)

JComboBox : colors in the selected value field
I have a JComboBox with a custom ListCellRenderer. However the JComboBox seems to change the colors of the Component that my ListCellRenderer creates when the Component is in the Selected value field. Some code is below...
import javax.swing.*;
import java.awt.*;
import java.util.*;
public class ComboBoxTest {
public static final void main(String[] args) {
JComboBox cbox;
Vector elements;
elements = new Vector();
elements.add("One");
elements.add("Two");
elements.add("Three");
cbox = new JComboBox(elements);
cbox.setRenderer(new MyRenderer());
cbox.setEditable(false);
JFrame frame = new JFrame();
JPanel content = (JPanel) frame.getContentPane();
content.add(cbox);
frame.pack();
frame.setVisible(true);
class MyRenderer implements ListCellRenderer {
public Component getListCellRendererComponent(
JList list,
Object value,
int index,
boolean isSelected,
boolean cellHasFocus)
String strValue;
JLabel label;
strValue = (String) value;
label = new JLabel("<" + strValue + ">");
label.setOpaque(true);
if( isSelected ) {
label.setForeground(Color.black);
label.setBackground(Color.green);
} else {
label.setForeground(Color.white);
label.setBackground(Color.black);
return label;
}This code simply creates a JComboBox with 3 String values, "One", "Two", and "Three". The renderer creates a JLabel with the String value enclosed in triangle brackets. The renderer also sets the colors of the JLabel to white on black if unselected and black on green if selected.
When I run this program, the list portion of the JComboBox looks correct, but the entry in the edit field is wrong. It has the enclosing triangle brackets around the selected String, but the colors are still the default black on gray.
What do I need to do to get the colors in the edit field to display correctly?
- JamesA JComboBox is similar to a JSpinner in the sense that it has an associated editor that has an associated textfield....check out the link shown below

hello all,
i am a relative beginner to java and am having a small bit of difficulty in a small venture, and was wondering if someone could help.
I am in the middle of creating a top-down tile-based turn-based engine. I am currently at very early stages.
- i have a class called "tile". This only contains code for two ints (TerrainType and MovementCost).
- I make a grid of references, and then apply a whatever.tile to each reference, using an array, which defines the map.
- The trouble is at the nestedloop, where i cannot apply an "ImageIcon" to class.tile.
How should i change my code? By the way, this is my 2nd version of this - The first version, used jLabels instead of class.tile, and it worked fine. However i couldnt figure out how to apply attributes to it.
*****CODE******
ImageIcon block = new ImageIcon("block.gif");
ImageIcon grass = new ImageIcon("grass.gif");
tile t0 = new tile();
tile t1 = new tile();
tile t2 = new tile();
tile t3 = new tile();
ArrayList tt = new ArrayList();
tt.add("0");
tt.add("0");
tt.add("0");
tt.add("1");
tt.add("x");
int max_rows = 2;
int max_cols = 2;
int x = 0;
tile[][] grid = new tile[max_rows][max_cols];
grid[0][0] = t0;
grid[0][1] = t1;
grid[1][0] = t2;
grid[1][1] = t3;
for (int r = 0; r < max_rows; r++) {
for (int c = 0; c < max_cols; c++) {
if (tt.get(0).equals("0")){
grid[r][c].setIcon(grass); <<<<error
tt.remove(0);}
else if (tt.get(0).equals("1")){
grid[r][c].setIcon(block); <<<<error
tt.remove(0);}
**********class code*****
package mapalpha;
public class tile {
int TerrainType;
int MovementCost;
public tile() {
}To add an 'attribute' to a JLabel: since JLabel extends from JComponent you can use the 'putClientProperty' and the 'getClientProperty' methods to store/retrieve attribute-type information in the component. See the method detail section for each method in the JComponent api.
On your current design: you can put anything you want in your custom Tile class - ImageIcon, JLabel, JPanel, an image...
class Tile
int terrainType, movementCost;
BufferedImage image;
ImageIcon icon;
JLabel label;
public Tile(args for instantiation if you like...)
protected void setIcon(ImageIcon icon)
this.icon = icon;
// other activity if you like
}If you want an image/graphics component you could have Tile extend JPanel or JLabel. Then you could override the 'paintComponent' method in JPanel and draw your image/graphics. If extending JLabel simply call 'setIcon' which will be a JLabel method - not the same as in the pseudo code above (which is a 'set' method for the Tile class). -
Complete beginners help.using ImageIcon and cant assign images
how do assign the ImageIcon for the front and back to this class.i have two gif files in the same directory. to test the card class i want to press the flip button to display the front and then the back. i am making simple card game but am very new to this and am stumbling at the basics.any help much appreciated. here is my attempt at the code.

ImageIcon i = new ImageIcon("path/filename.ext");
note: the path can be relative (i.e. "images/pict1.gif")
or explicit ("c:/project1/images/pict1.gif").
Hope this is what you're looking for. -
Hi, I'm trying to draw a ComboBox with animated gifs in the selection list.
And the problem is that the gifs are painted but always with the same image. Here it is part of the source code of the ListCellRenderer class.
In the paint(Graphics g) function I have:
"g.drawImage(((ImageIcon)icon).getImage(),rect.x,rect.y,this);"
and if I use the following we've the same result
"icon.paintIcon(this,g,rect.x,rect.y);"
It is also rewritten the function: "imageUpdate" and it makes the gif to be repainted every 100 ms (that's ok) but always paints the same image so it doesn't animate.
Any ideas?The solution:
public Component getListCellRendererComponent(JList list, Object value,
int index, boolean isSelected, boolean cellHasFocus) {
JLabel tmpLabel = new JLabel();
if (value instanceof ImageIcon) {

Adding pictures into an Array?
The following is a BlackJack Program my group and I made. So far, it seems to work and would likely net us a 100% when we hand it in. However, we wish to go that extra mile and add pictures, cards in particular, something that should obviously be in any card game! I've been fiddling around with ImageIcon and Image but I don't have a clue how to implement these or how to get them working correctly. Also, it would be best if the pictures could be loaded into an array, which would allow the program to function basically the same way with little editing.

Instead of having a JLabel with "Ace", "Eight", etc appear, how would one make pictures appear? How does one do this with an array?
Edited by: Funkdmonkey on Jan 1, 2008 7:45 PMI guess an array or perhaps better a hashmap where the image is the value and the card (a great place for an enum!) is the key would work nicely. Oh, and you can find a great public domain set of card images here:
http://www.eludication.org/playingcards.html
Finally, your code appears to be suffering from the God-class anti-pattern. You would do well to refactor that beast.

TreeCellRendere updating icons
I have a TreeCellRederer which changes the icons of JTREE when openen/closing items (linked to start/stop applications)
When an item (application) is open and i switch to another item, the icon does not change (correct because app is still running). When i select an item and close the application, the icon is changed correctly (from closed to open and vise versa).
When an item (app3) is open and i switch to another application (app2) and then close the app2, my cursus jumps to item 0 (top level) and the icon of the app2 is closed. Then i close app3 (without selecting it first). Now it is goes wrong, the icon is not changed. This is because the line is not rendered.
I can force closing of the item by jumping to the last item in the list and then to the first item in the list "removeFromActiveApplicationList(String application)" method, but this is a bit of overkill.
The problem is that the item-row is not rendered when application is closed without the item be-ing active. Any idea how to solve this?
I will include all coding but icon-iconimages.

When you say "the JLabel changes" I'm guessing you mean that the JLabel variable named "imageLabel" was the thing that changed? That won't change the GUI's reference to the original JLabel object.
Which is what you have to change. You have a reference to that object in the form of the "imageLabel" variable; to change the object you call one of its methods, like maybe setIcon() or something... whatever your ImageManager class is doing to create the label in the first place. -
Change colors in the png - keep transparency
I load a png-file as ImageIcon into a JLabel as setIcon(). A color of the png (generally color white) is defined for transparency, that in the JLabel is represented correctly as transparency.
I want to convert now another dark color in ImageIcon like new Color (0,0,0) into a bright-grey-color like new Color (244,244,244), after the transformation transparency effect should kept by color white.
How can that be done, please?BufferedImage is the easiest interface to the pixels yes. You can always load your images as BufferedImage instances and pass those to your ImageIcon objects; if you ever want the image back you simply cast the return value of ImageIcon.getImage() to BufferedImage.

The problem is that when a resize that needs a setLocation() to go with it, the frame flash/flicker a lot. I already tried to set "sun.awt.noerasebackground" to "true" but it didn't help me. Is there another way to solve the flickering problem?
I notice on normal frames, there is an outline drawn as the mouse moves around, then the windows resize/setLocation at mouse release events. How can I do this (if the flash/flicker problem can't be solved)?
Thank you very much for your time!!
Cheers!Thanks for the reply! But I don't have a problem with moving the undecorated JDialog. It's the resize operations that I try to do. If the resize operations need to resize and setLocation (i.e NW, SW, NE, W, N resize) then my JDialog will flash... I doubt that you need to read it... If you are familiar with this kind of things then once you compile and run it, you will probably know the fix right away...
