I'm new to Java GUI. I'm not good to thread programming. I just wondering if there is any easy way to create and display a JFrame from another JFrame method. I give you my code. The SettingsForm calls the Test which is a JFrame via the close() method. All imports have been included.
class SettingsForm extends JFrame{
JButton submit,defaultOption;//koumpia kataxwrhshs-akurwshs
JLabel host, port, dbName, user, pass;//koina JLabel.Etiketes host, port, dbName, user kai password
JTextField hostT, portT, dbNameT, userT, passT;//koina JTextField.perioxh egrafhs twn host, port, dbName, user kai password
ImageIcon img;
public SettingsForm()//arxikh dhmiourgia tou frame
{
super("Data Base Information");
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
this.img = new ImageIcon("logo.png");
}//constractor
public void createForm(int rows,int columns,int vgap,int hgap)//orizei sto panel tou frame topothethsh sumfwna me to GridLayout
{
JPanel panel=new JPanel();
GridLayout g=new GridLayout(rows,columns,vgap,hgap);
panel.setLayout(g);
this.setContentPane(panel);
this.addElements();
this.setIconImage(this.img.getImage());
this.pack();
submit.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
if (hostT.getText().length()!=0 && portT.getText().length()!=0 && dbNameT.getText().length()!=0 && userT.getText().length()!=0 && passT.getText().length()!=0)
{
try {
CreateSettings s = new CreateSettings("Endocrino\\settings.txt");
s.write(hostT.getText(), portT.getText(), dbNameT.getText(), userT.getText(), passT.getText());
close();
} catch (FileNotFoundException e1) {
e1.printStackTrace();
} catch (Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
else{
JOptionPane.showMessageDialog(null,"All items must be filled","Warning",JOptionPane.ERROR_MESSAGE);
}
}
});
defaultOption.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{ hostT.setText("localhost");
portT.setText("3306");
dbNameT.setText("endocrino");
userT.setText("endo");
passT.setText("1234");
}
});
}//createForm
public void addButtons()//prosthetei to koumpi kataxwrhshs sto panel
{
Container c=this.getContentPane();
this.submit=new JButton("OK");
this.defaultOption=new JButton("Set Default");
c.add(submit);
c.add(defaultOption);
}//addButtons
public void addHost()//prosthetei to label kai text field gia egrafh tou host apo ton xrhsth

{

c.add(port);
c.add(portT);
}//addPort
public void addDBName()//prosthetei to label kai text field gia egrafh tou Data Base Name apo ton xrhsth
{
Container c=this.getContentPane();
this.dbName=new JLabel("Data Base Name");
this.dbNameT=new JTextField();
c.add(dbName);
c.add(dbNameT);
}//addDBName
public void addUser()//prosthetei to label kai text field gia egrafh tou user apo ton xrhsth
{
Container c=this.getContentPane();
this.user=new JLabel("User");
this.userT=new JTextField();
c.add(user);
c.add(userT);
}//addUser
public void addPassword()//prosthetei to label kai text field gia egrafh tou password apo ton xrhsth

public void close(){
this.dispose();
Test t=new Test();
t.createForm(6,1,3,3);
t.showForm();
t.dosCommands();
}//close
}//SettingsForm
And the Test class
class Test extends JFrame{
JLabel firstMsg, progressMsg, enFolderMsg, dbMsg, shortcutMsg, finishedMsg;//koina JLabel.Etiketes host, port, dbName, user kai password
ImageIcon img;
public Test()//arxikh dhmiourgia tou frame
{

this.setDefaultCloseOperation(EXIT_ON_CLOSE);
this.img = new ImageIcon("logo.png");
Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
this.setLocation(dim.width/2-this.getSize().width/2, dim.height/2-this.getSize().height/2);
}//constractor
public void createForm(int rows,int columns,int vgap,int hgap)//orizei sto panel tou frame topothethsh sumfwna me to GridLayout
{

this.setContentPane(panel);
this.addElements();
this.setIconImage(this.img.getImage());
this.pack();
}//createForm
public void addProgressMsg()//prosthetei to minima "Plese wait.."

public void addDBMsg()//prosthetei to label gia tin dimiourgia tis basis
{

public void addElements(){

this.addEnFolderMsg();
this.addDBMsg();
this.addShortcutMsg();
this.addFinishedMsg();
}//addElements
public void close(){
this.dispose();
System.exit(0);
}
public void dosCommands() throws InterruptedException{
revalidateItems();repaintItems();
this.enFolderMsg.setText("Creating Endocrino Folder...");

}//Test
My problem is that the Test frame window is opened but it's JLabels not displaying...
