I have a class PanelLogiciel ( a cardLayout to show interface for connexion or interface for the market) and the Class PanelAcces(interface for connection):
I would like to use an ActionListener on a JButton from PanelAcces,if you use the JButton,PanelLogiciel will change from PanelAcces to another JPanel with the CardLayout. Hope you can help and sorry if it's a stupid question but can't find ...

When I started my project about a Dictionary from Chinese to English, I got some problems.First,
I used the addCaretListener method to realize that when I changed the cursor in wordLine,changed the context in JList and show the result.But here a problem comes,If I changed the cursor, the JList were clear,and not show anything.
Another problem is I want to invoke the http video API to realize the video play. As I add the video button and add the audio method to realize ,I failed.
I'll appreciate if you can solve them.
This is part of my code:

So you first of call should be the tutorals
How to use Lists
Selecting items in a list
Adding items to and removing items from a list
Which will give you the basic information you need to proceeded.
Based on your available code, you should not be adding a JLabel to the ListModel, you should never add components to data models, as more often than not, Swing components have there own concept of how they will render them.
In your case, you're actually lucky, as the default ListCellRenderer is based on a JLabel and will render Icon's automatically, for example
import javax.swing.DefaultListModel;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JList;
import javax.swing.JScrollPane;
import javax.swing.SwingUtilities;
import javax.swing.event.ListSelectionEvent;
import javax.swing.event.ListSelectionListener;
public class Test {
public static void main(String[] args) {
new Test();
}
public Test() {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
DefaultListModel model = new DefaultListModel();
model.addElement(new ImageIcon("mt01.jpg"));
model.addElement(new ImageIcon("mt02.jpg"));
model.addElement(new ImageIcon("mt03.jpg"));
JList list = new JList(model);
list.setVisibleRowCount(3);
list.addListSelectionListener(new ListSelectionListener() {
#Override
public void valueChanged(ListSelectionEvent e) {
if (!e.getValueIsAdjusting()) {
System.out.println(list.getSelectedIndex());
}
}
});
JFrame frame = new JFrame("Test");
frame.add(new JScrollPane(list));

I have a problem when i add a jpanel to existing jpanel!
i want jlist at center loction and jbuttom in south location!
i can see the jlist, but the jbuttom won't show on!
I'm using Eclipse 3.0 version.

setLayout(new BorderLayout());
setSize(450 ,400);
String animals_list[] = new String[AquaPanel.swims.size()];
LinkedList<Swimmable> ir = new LinkedList<Swimmable>(AquaPanel.swims);
for(int i=0;i<ir.size();i++)
{
animals_list[i]=(i+1+". "+ir.get(i).toString());
}
list = new JList<String>(animals_list );
list.setFont(new Font("Tahoma",Font.BOLD,15));
list.setSize(450, 300);

Change = new JButton("Change Color");
Change.addActionListener(this);
add(Change,BorderLayout.CENTER);
repaint();
}
#Override
public void actionPerformed(ActionEvent e) {
}
}
please help!
You have a subtle bug. In the constructor of JPanelDecorator you have :
public JPanelDecorator()
{
//....
add(list,BorderLayout.CENTER);
//...
add(Change,BorderLayout.CENTER); // center again...
//...
}
But what you need is this:
public JPanelDecorator()
{
//....
add(list,BorderLayout.CENTER);
//...
add(Change,BorderLayout.SOUTH); // south
//...
}
I'm new to jung and i need help on how to learn. I searched a lot of places, but i haven't found a step by step guide. Im trying to create a gui that will add vertexes only if they selected the right menu, and entered a proper name.

I have created an application in Java Swing. I offer the option to change the look and feel of the application from a menu, but after adding a new tab in JTabbedPane, it is not getting updated with the new look and feel.
I have already used this code:
Window windows[] = Frame.getWindows();
for(Window window : windows) {
SwingUtilities.updateComponentTreeUI(window);
}
Leveraging #Andrew's example and this old thing, it seems to work for me.
