I'm having an array of objects of class A which contain an array of objects of class B.
I've got quite a few questions: (Coding examples would be of great help)
How can I use a JTree with parent node as Object A and children node as B's and populate it?
Assuming that the entire JFrame is divided into two panels(one containing the JTree and another JPanel which displays object's attributes corresponding to the option selected on the JTree) how can I make this happen? As of now, I'm able to hard-code the values into the JTree.
I've searched a lot for examples on the net but was able to find only basic examples.
This is what I've done so far:
public class A {
int a1=10;
int a2=20;
B bobj[]=new B[2];
A(){
bobj[0]=new B();
bobj[1]=new B();
}
}
class B {
int b=30;
}
In my Jtree code:
import javax.swing.tree.TreeModel;
public class try1 extends javax.swing.JFrame {
static A a2=new A();
/** Creates new form try1 */
public try1() {
initComponents();
}

I found this examplehere
1. Since the eg's initial format is an array of strings,they're using the hastable. Since I'm using a class of objects(A) which contains objects of B, how should I do it(I'm getting an error above).
2.I've attached the layout of my Frame. I've hardcoded the Jtree in the screenshot. What should I do so that if I click on any Jtree node, I'm able to view the details on JTextField near it?
Based on your program fragment and image, you may want to start by studying the TreeDemo example discussed in How to Use Trees. Related examples may be found here.

i'm currently working on a java desktop project , oddly enough whenever i hit the run button , the Jpanel doesn't show up. I declared this as main but still it doesn't works. Any ideas ?
Here is the code for my Jpanel form.
Thanks in advance!.

Nothing "odd" about this. Your ventana class is a JPanel, and yes, you create it and set it visible, but a JPanel by itself can not display, and to in fact have it show, it needs to be part of a visible "top-level window" such as a JFrame or JDialog. So if you want to show this JPanel in its own separate dialog window, put it into a JDialog, pack() the dialog, and then set the dialog visible. Or the quick and dirty way to do this is to put the ventana JPanel into a JOptionPane. e.g.,
JOptionPane.showMessageDialog(null, new ventana());
A JOptionPane will then create and display a modal JDialog that will display your ventana object.
Note that the ventana class name should begin with an upper-case letter, like all Java class names should.

What you have defined is a JPanel. A JPanel is not a top-level component. It can't be made visible on its own, but must be added to a JFrame.
Replace your run method body by
gui gui = new gui();
JFrame f = new JFrame();
f.add(gui);
f.pack();
f.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
f.setVisible(true);
And please, give a better name than gui to your class (something like PasswordPanel, for example), and respect the Java naming conventions: classes start with an uppercase letter.
Instead of this:
public void run() {
new gui().setVisible(true);
}
Put it in a JFrame first, JPanel can't display by itself. For example:
public void run() {
JFrame frame = new JFrame("your window");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(new gui());
frame.pack();
frame.setVisible(true);
}
By the way, class name should being with uppercase letters. So you may want to name your gui class as Gui or GUI.
I'm using a JPanel on a JFrame and I have a TitledBorder on the JPanel. I create the JPanel with the titled border in NetBeans and I can see my title and the etched frame. When I run, I only see the title but not the etched frame. Any idea why I can't see the etched frame? I've tried setting the look and feel but can't get the frame to show up and it looks odd having the title with no border.
Running Java 1.7 on Windows 7. I don't recall this happening when we were using java 1.6.
Here's sample code:

This is not an answer yet
This is what I get in 1.7:
Is it not what you want?
Edit:
Try running this:
public class NewJFrame extends JFrame {
public NewJFrame() {
JPanel p = new JPanel();
p.add(new JLabel("AAAAA"));
p.setBorder(BorderFactory.createTitledBorder("Title"));
add(p);
setLocationRelativeTo(null);
setDefaultCloseOperation(EXIT_ON_CLOSE);
pack();
setVisible(true);
}
public static void main(String args[]) {
new NewJFrame();
}
}
It's very minimal and should narrow the options. This is what I get:
I'm doing a homework assignment using HashMap with GUI. The user will enter a Country, and the Capital of that country, and press Add, this will add those two Strings to the map, and it should add the Capital to the list on the right. The search function is next. The user will be able to type the name of the country, and it will highlight that countries capital in blue on the right among the other capitals that were added. Here is what it should look like.
How can I copy the contents of my hashMap to my JList? I only need the Capitals to display so I can search them.
Any help is appreciated, thank you.
P.S. Sorry for the generated code, the variable declarations are at the bottom because of it.

Look into the documentation of JList and it's many example use cases.
You can do something like this by modifying your adding values event using setListData() method:
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt)
{
String text = countryInput.getText();
String text2 = capitalInput.getText();
hashMap.put(text,text2);
capitalList.setListData(hashMap.values().toArray());
}
I've successfully tested it:
MapPanel mp = new MapPanel();
JFrame frame = new JFrame("Countries and capitals");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(mp);
frame.pack();
frame.setVisible(true);
After adding a country, its capital is shown up in the right list. Problem solved ;-)
I am developing an application using Java, Swing. It will be mainly used in order to study oscillograms against pentagrams for medical purposes. It is wished that the user can keep notes on top of the images (presumably something like the pencil used in Window's paint).
Please, keep in mind that every time the user loads an image, the following mouse motion listener gets attached to it (in order to make the image draggable for usability reasons):
public class DragMouseListener implements MouseMotionListener {
JLabel jl;
int imageX, imageY;
public DragMouseListener(JLabel jlabel) {
this.jl = jlabel;
jl.addMouseMotionListener(this);
}
#Override
public void mouseDragged(MouseEvent e) {
updateImagePosition(e);
}
#Override
public void mouseMoved(MouseEvent e) {
}
private void updateImagePosition(MouseEvent e) {
imageX = e.getX();
imageY = e.getY();
jl.setLocation(imageX, imageY);
}
}
Until now I am unable to even come close to a way of implementing it and I cannot find any references of the issue in the Internet. Any help (even rough ideas) would be much appreciated. Thanks in advance.

I tried what you asked for DragMouseListener but found it very uncomfortable so used JInternal Frame it works fine(but you can still drag images inside JInternal Frame,as I implemented what you asked for).Insted of hand free writing,I used JEditorPane(you can add hand written thing if you want,but it will be a mess) with accessible parent JScrollPane so that you can type how much you want.
You can drag JInternal Frame easily:
Note: I have used NetBeans GUI Builder for this and suggest you too to use any GUI builder as it makes
typing work easy.
