Java JDialog Passing Object From Within the JDialog using a Sumbit Button from the JDialog

ive searched online for the answer for a few hours now, so far i havent found anything helpful, i have a JDialog that is supposed to send an object back to the JPanel that called it, after running the code several times i noticed that the JPanel Constructor Finishes before i can press the Save button inside the JDialog,
my problem is this,
how do i pass the object from the JDialog to the JPanel and in which part of the Jpanel Code do i write it?
Here is the JPanel Code:

So in short in the JDialog i need to get information from comboboxes and texfields and send that data to an object constructor, and on the "Save" button click i need to transfer the Object from the JDialog that i created with the constructor to the JPanel, how do i do it?

i realized i can send the JPanel to the JDialog and in the JDialog's code where i create the object, i modify the Jpanel's Hashset accordingly

Can't get custom JPanel to show up on JDialog

I have developed my own properties type data structure for setting some basic data within an application. I was just using the regular properties, but I wanted the user to be able to edit these and then have notes, display order, and whether or not they are active. Also, to be able to group the different properties.
I created a panel that displays the property with an "Edit" button for them to actually make changes.
Then another panel that loads a group and displays all of the properties for that group.
Both of those panels seem to work fine. Then when I create a JDialog that should load all of the groups into a panel each, I can't get it to display. I have toyed with lots of layouts and no luck. In addition, I will need a scrollpane so when they grow overtime.
I am not quite sure what to do at this point...if I add buttons to the panel, it scrolls just fine, so I assume something is wrong with the Panel I am trying to add.
Here is the property group class:
import java.util.LinkedHashMap;
public class SMoKEPropertyGroup {
private String name = null;
private String notes = null;
private int displayOrder = 0;
private boolean active = true;
private LinkedHashMap<String, SMoKEProperty> properties = new LinkedHashMap<>();
public SMoKEPropertyGroup(String name, String notes, int displayOrder, boolean active) {
super();
this.name = name;
this.notes = notes;
this.displayOrder = displayOrder;
this.active = active;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getNotes() {
return notes;
}
public void setNotes(String notes) {
this.notes = notes;
}
public int getDisplayOrder() {
return displayOrder;
}
public void setDisplayOrder(int displayOrder) {
this.displayOrder = displayOrder;
}
public boolean isActive() {
return active;
}
public void setActive(boolean active) {
this.active = active;
}
public LinkedHashMap<String, SMoKEProperty> getProperties() {
return properties;
}
public void addProperties(SMoKEProperty property) {
this.properties.put(property.getName(), property);
}
}
Here is the actual property class:
public class SMoKEProperty {
private String groupName = null;
private String name = null;
private String value = null;
private String notes = null;
private int displayOrder = 0;
private boolean active = true;
private String displayableName = null;
public SMoKEProperty(String groupName, String name, String value, String notes, int displayOrder, boolean active) {
super();
this.groupName = groupName;
this.name = name;
this.value = value;
this.notes = notes;
this.displayOrder = displayOrder;
this.active = active;
}
public String getGroupName() {
return groupName;
}
public void setGroupName(String groupName) {
this.groupName = groupName;
}
public String getName() {
return name;
}
public String getDisplayableName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
public String getNotes() {
return notes;
}
public void setNotes(String notes) {
this.notes = notes;
}
public int getDisplayOrder() {
return displayOrder;
}
public void setDisplayOrder(int displayOrder) {
this.displayOrder = displayOrder;
}
public boolean isActive() {
return active;
}
public void setActive(boolean active) {
this.active = active;
}
#Override
public String toString() {
return "SMoKEProperty \n" + " groupName=" + groupName + "\ndisplayableName=" + getDisplayableName() + "\nname="
+ name + "\nvalue=" + value + "\nnotes=" + notes + "\ndisplayOrder=" + displayOrder + "\nactive="
+ active + "\n\n";
}
}

Java GUI use one button to add multiple text fields to a text file?

I have to create a GUI that takes the input for multiple text fields, and when the user clicks one button, it adds all of the input to a text file. All the text fields will have to do with all the parts of an mp3 file. (artist/album, etc) Then, once the mp3 files are added to the text file, I have to create a button to edit or delete them. I'm confused as to how to make an "add" button for multiple text fields. Here is what I have so far:
public musicLib()
{
setLayout(new FlowLayout());
// Song Row
itemLabel = new JLabel("Item Code: ");
add(itemLabel);
itemCode = new JTextField(10);
add(itemCode);
descriptionLabel = new JLabel("Description: ");
add(descriptionLabel);
description = new JTextField(10);
add(description);
artistLabel = new JLabel("Artist: ");
add(artistLabel);
artist = new JTextField(10);
add(artist);
albumLabel = new JLabel("Album: ");
add(albumLabel);
album = new JTextField(10);
add(album);
// Buttons
addButton = new JButton("Add");
add(addButton);
Event e = new Event(); error"no suitable constructor found"
addButton.addActionListener(e); // error"incompatible types"
addButton.addActionListener(new ActionListener()
{
String nl = "\n",
data = "";
public void dataWriter(String data, String fileName) throws IOException {
File file = getFileStreamPath(fileName); // error"cannot find symbol"
if (!file.exists()) {
file.createNewFile();
}
FileOutputStream writer = openFileOutput(file.getName(), Context.MODE_PRIVATE); // error"cannot find symbol"
for (String string: data) // error"for- each not applicable to expression type"
{
writer.write(string.getBytes());
writer.flush();
}
writer.close();
}

Thank you guys very much for your help. I just need some help getting the one button to add multiple text field inputs to the text file. Thanks in advance!

This chunk, will be a part of the initial gui setup function:
/**
* On click listener for the add button
*/
addButton.addActionListener(new ActionListener() {
String nl = "\n",
data = "";
public void actionPerformed(ActionEvent ae){
data += "Label: " + albumLabel.getText() + nl;
data += "Artist: " + albumArtist.getText() + nl;
/*
* Repeat the same for any other text fields you have
*/
dataWriter(data, "test.txt");
}
});
And here is your file writer:
public void dataWriter(String data, String fileName) {
File file = getFileStreamPath(fileName);
if (!file.exists()) {
file.createNewFile();
}
FileOutputStream writer = openFileOutput(file.getName(), Context.MODE_PRIVATE);
for (String string: data){
writer.write(string.getBytes());
writer.flush();
}
writer.close();
}

If I correctly understand you, you want something like that;
StringBuilder sb = new StringBuilder();
sb.append("ItemLabel: "+itemLabel.getText()+"\n");
sb.append("Description: "+description.getText()+"\n");
and add what you need. When you write to file
out.write(sb.toString());

I wrote this very quick program to read and write field data using a Map of fields. The map consists of components and metadata on how to lay it out and whether its information is exportable or not.
It is far from complete, but with a little file IO, you can store and retrieve information and send it to the form as long as the incoming data matches the "schema" defined in the applications parsing logic.

Window after the "Edit" button is clicked.
Figure 2
Output after all fields' data has been exported to text; using the "Add" button.

How do I add 2 separate JPanels together to get 1 JPanel?

Bidirectional databinding on WindowBuilder seems not to work

I'm developing my first JDialog with Eclipse Juno, WindowBuilder, "Swing Automatic Databinding" (beansbinding-1.2.1.jar) on Java7 SE.
I'm curious to test auto-databinding
I got an editing dialog for the class User with the help of Eclipse Databinding GUI only.
package it.marcuzzi.databindtest;
public class User {
private String name;
private int age;
public User() {}
public String getName() {
return name;
}
public int getAge() {
return age;
}
public void setName(String name) {
this.name = name;
}
public void setAge(int age) {
this.age = age;
}
}
My dialog opens with its text fields containing correct initial values from a User instance. When I modify text-fields texts and then click the Ok button, I can see no changes to the User instance.
Here is my dialog code .....

Binding update strategies are all READ_WRITE so I can't understand why it doesn't update User instance!
Any idea ?

Actually, it is updating the User instance but your widgets aren't get notified about it. You have to fire a PropertyChangeEvent in your setters. Here's an example:
import java.beans.*;
public class Foo {
private int bar;
private PropertyChangeSupport pcs = new PropertyChangeSupport(this);
public int getBar() { return bar; }
public void setBar(int bar) {
int oldValue = this.bar;
this.bar = bar;
pcs.firePropertyChange("bar", oldValue, bar);
}
public void addPropertyChangeListener(PropertyChangeListener pcl) {
pcs.addPropertyChangeListener(pcl);
}
public void removePropertyChangeListener(PropertyChangeListener pcl) {
pcs.removePropertyChangeListener(pcl);
}
}
