My problem is that I have a class that when the user types out the text displayed dispose() is called, which works the first time but if you don't close the program and open it again, dispose() is called, but doesn't do anything which breaks the program.
public class TypeMenu extends JDialog {
protected final JPanel contentPanel = new JPanel();
protected static JTextField inputTxtField;
protected static JTextField textField;
protected static JTextField introTxtField;
/**

*/
public static void main(String[] args) {
try {
Easy dialog = new Easy();
dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
dialog.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* Create the dialog.
* #param introTxtField2
* #param textField2
* #param inputTxtField2
*/
public TypeMenu(JTextField inputTxtField2, JTextField introTxtField2, JTextField textField2) {
setBounds(100, 100, 450, 300);
getContentPane().setLayout(new BorderLayout());
contentPanel.setBorder(new EmptyBorder(5, 5, 5, 5));
getContentPane().add(contentPanel, BorderLayout.CENTER);
contentPanel.setLayout(null);
contentPanel.add(getInputTxtField());

}

inputTxtField = new JTextField();
inputTxtField.setHorizontalAlignment(SwingConstants.CENTER);
inputTxtField.addKeyListener(new KeyAdapter() {
#Override

textField.setText(strField.substring(1));
System.out.println(length);
System.out.println(strField);
if (length - 1 <= 0) {
dispose();
}
} else {
inputTxtField.setText(" ");
}
}
});
inputTxtField.setBounds(56, 177, 314, 40);

your text field is static so he will have only one instance across the application.
so in the method getIntroTxtField() you have if statement that says :
if (introTxtField == null)
in the first time this condition is true but when you create the new instance this condition is false because the instance of the static field is all ready created in the first and you are adding the key listener inside the condition
so the action listener will be added only in the first creation.
if you need to keep the static because you need in other class you need to remove the == null
protected JTextField getInputTxtField() {
inputTxtField = null;
{
inputTxtField = new JTextField();
inputTxtField.setHorizontalAlignment(SwingConstants.CENTER);
inputTxtField.addKeyListener(new KeyAdapter() {
#Override
public void keyReleased(KeyEvent arg0) {
String strField = textField.getText();
char key = arg0.getKeyChar();
int length = strField.length();
if (Character.toLowerCase(strField.charAt(0)) == Character.toLowerCase(key)) {
inputTxtField.setText(" ");
textField.setText(strField.substring(1));
System.out.println(length);
System.out.println(strField);
if (length - 1 <= 0) {
dispose();
}
} else {
inputTxtField.setText(" ");
}
}
});
inputTxtField.setBounds(56, 177, 314, 40);
inputTxtField.setColumns(10);
}
return inputTxtField;
}
or remove the static from you field declaration static is used in
shared instace only when you are using only one instace across the
application like sessionFactory or any thing that need to be created
only one time.
you code is a lot to read but i think your problem is that you are calling the dispose() of the wrong object. may you are calling it always for the first object and you are creating a new one, and the dispose of this new dialog will never be call,Check you code may be you are creating many object and the dispose() is not called at all. make sure that you have full control of your objects instance to know if you are diposing the wanted dialog.
Hi guys im trying to set a string value on my main frame with a value generated in an other frame, but i dont quite know how to do it this is my code so far.
This is my mainframe opens the query frame where i input the data
public class InfoCd extends JFrame {
private JPanel contentPane;

} catch (Exception e) {

}
}
});
}
Connection conn=null;

Statement statement = conn.createStatement();

table.setModel(DbUtils.resultSetToTableModel(rs));
//insert delete update
} catch (Exception e2) {

i have two jframes in my app, Addnmember.java and Frame1.java
Frame1 is the main Jframe,
i want when someone presses the Add button, the Addmember will be shown, i have done this with this code, and every thing is fine:
AddB.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
frame.dispose();
AddMember addmem = new AddMember();
addmem.setVisible(true);
}
});
But in the new Jframe, i want to come back again when Done Bt is selected, i have done this whit this code:
btnNewButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
//dispose();
Frame1 addmem = new Frame1();
addmem.setVisible(true);

thanks.
As to why your second Frame1 shows no data, I'm not 100% sure, but perhaps it has something to do with your failure to close your database connection. Regardless, it seems wasteful and even potentially dangerous to want to gather the database data twice when you've already obtained it once, and to create your Frame1 GUI twice when you've already created it once.
You should re-design your GUI. The main JFrame GUI should remain visible, and the Frame1 window should be a modal JDialog. As a modal dialog, it will prevent users from being able to interact with the parent JFrame until the dialog is no longer visible.
Note that to get started requires only a few changes:
in Frame1.java
AddB.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
// frame.dispose();
AddMember addmem = new AddMember(Frame1.this); // !!
addmem.setVisible(true);
}
});
in AddMember.java
class AddMember extends JDialog {
public AddMember(JFrame frame) {
super(frame, "", ModalityType.APPLICATION_MODAL);
setTitle("\u0627\u0641\u0632\u0648\u062F\u0646 \u0639\u0636\u0648 \u062C\u062F\u06CC\u062F");
// !! setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
btnNewButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
// dispose();
dispose(); // !!
// !! Frame1 addmem = new Frame1();
// addmem.setVisible(true);
}
});
Also, you'll want to avoid null layouts and setBounds(...) as this will lead to very rigid, hard to debug and improve programs.
I'm creating the app using Eclipse Kepler...I've created 3 database in Eclipse- database, entity and UI. In database, it contains ContactDAO,UserDAO and DBManager(for database connection) . In Entity, it contains Contact and User. In UI, it contains ContactAdd, COntactDetails , ContactList, LoginFrame and MenuFrame JFrames. Now, I'm stuck at ContactList frame... it contains ComboBox and I've tried to run it but I can't get the names... this is the code:

Then, I have also created the ContactDetails frame that contains the contact details, edit save and close buttons, and Delete label set as Image. The project says when the edit button is clicked, the save button will be visible... I don't know how to do that...Here's my code :
public class ContactDetails extends JFrame {
private JPanel contentPane;
private JTextField txtName;
private JTextField txtMobile;
private JTextField txtHome;
private JTextField txtEmail;
private JButton btnEdit;
private JButton btnSave;
private ContactList parentFrame;
private Contact contact;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
ContactDetails frame = new ContactDetails(null,null);
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the frame.
*/
public ContactDetails(ContactList f,Contact c) {
this.parentFrame = f;
this.contact=c;
setTitle("Contact Details");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 450, 300);
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
setContentPane(contentPane);
contentPane.setLayout(null);
JLabel lblImage = new JLabel("");
lblImage.setIcon(new ImageIcon(ContactDetails.class.getResource("/images/kitty.png")));
lblImage.setBounds(34, 28, 79, 70);
contentPane.add(lblImage);
JLabel lblName = new JLabel("Name:");
lblName.setBounds(119, 48, 46, 14);
contentPane.add(lblName);
txtName = new JTextField(contact.getName());
txtName.setBounds(162, 45, 169, 20);
contentPane.add(txtName);
txtName.setColumns(10);
JLabel lblMobile = new JLabel("Mobile:");
lblMobile.setBounds(119, 93, 46, 14);
contentPane.add(lblMobile);
txtMobile = new JTextField();
txtMobile.setBounds(162, 90, 169, 20);
contentPane.add(txtMobile);
txtMobile.setColumns(10);
JLabel lblHome = new JLabel("Home:");
lblHome.setBounds(119, 141, 46, 14);
contentPane.add(lblHome);
txtHome = new JTextField();
txtHome.setBounds(162, 138, 169, 20);
contentPane.add(txtHome);
txtHome.setColumns(10);
JLabel lblEmail = new JLabel("Email:");
lblEmail.setBounds(119, 186, 46, 14);
contentPane.add(lblEmail);
txtEmail = new JTextField();
txtEmail.setBounds(162, 183, 169, 20);
contentPane.add(txtEmail);
txtEmail.setColumns(10);
JButton btnSave = new JButton("Save");
btnSave.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
contactAdded();
}
});
btnSave.setBounds(184, 227, 74, 23);
contentPane.add(btnSave);
JButton btnEdit = new JButton("Edit");
btnEdit.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
editContact();
}
});
btnEdit.setBounds(110, 227, 74, 23);
contentPane.add(btnEdit);
JButton btnClose = new JButton("Close");
btnClose.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
goBack();
}
});
btnClose.setBounds(257, 227, 74, 23);
contentPane.add(btnClose);
JLabel lblDelete = new JLabel("");
lblDelete.addMouseListener(new MouseAdapter() {
#Override
public void mouseClicked(MouseEvent arg0) {
removeContact();
}
});
lblDelete.setIcon(new ImageIcon(ContactDetails.class.getResource("/images/trush.png")));
lblDelete.setBounds(365, 28, 46, 54);
contentPane.add(lblDelete);
}
private void contactAdded() {
// TODO Auto-generated method stub
String name=txtName.getText();
String mobile=txtMobile.getText();
String home=txtHome.getText();
String email=txtEmail.getText();
Contact contact = new Contact(name, mobile, home, email);
if(ContactDAO.create(contact)){
JOptionPane.showMessageDialog(contentPane, "Contact successfull saved!");
}
else {
JOptionPane.showMessageDialog(contentPane, "Contact not save!");
}
}
private void goBack() {
// TODO Auto-generated method stub
parentFrame.setVisible(true);
this.dispose();
}
private void removeContact() {
// TODO Auto-generated method stub
String name=txtName.getText();
String mobile=txtMobile.getText();
String home=txtHome.getText();
String email=txtEmail.getText();
Contact contact = new Contact(name, mobile, home, email);
if(ContactDAO.delete(contact)){
JOptionPane.showMessageDialog(contentPane, "Contact deleted");
}
else {
JOptionPane.showMessageDialog(contentPane, "Contact delete unsuccessful");
}
}
private void editContact() {
// TODO Auto-generated method stub
String name=txtName.getText();
String mobile=txtMobile.getText();
String home=txtHome.getText();
String email=txtEmail.getText();
Contact contact = new Contact(name, mobile, home, email);
if (ContactDAO.update(contact)){
JOptionPane.showMessageDialog(contentPane, "Contact successfully updated");
}
else {
JOptionPane.showMessageDialog(contentPane, "Contact update unsuccessful");
}
}
}
Also, the Save button is tricky for me... It seems that after clicking the Save button, a message should pop up for confirmation that should include (OK) button. When the (ok)button is clicked, Save button will be disabled and Edit button will be enabled again. All Text fields will be disabled. The (Delete Icon button) also needs a prompt box that includes (Yes, no and cancel) buttons. If confirm, contact will be deleted and user will be brought back to the contacts list frame... How should I do it?
Tell me if I have to create another JFrame or DAO...
You need somthing like this for your save button and same for remove button:
int showConfirmDialog = JOptionPane.showConfirmDialog(new JFrame(), "Approve?","Title",JOptionPane.YES_NO_OPTION);
if(showConfirmDialog == JOptionPane.YES_OPTION){
btnSave.setEnabled(false);
btnEdit.setEnabled(true);
txtName.setEnabled(false);
//other fields
} else {
//If no or cancel actions
}
Read tutorial for dialogs.
Watch showConfirmDialog(...)
I know this is ill advised but I am using absolute layout and trying to go from panel to panel and was curious how to do this.
public class Mainscreen extends JFrame {
private JPanel Home;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Mainscreen frame = new Mainscreen();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
public Mainscreen() {
final Dataentrylog DEL = new Dataentrylog();
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setResizable(false);
setBounds(100, 100, 618, 373);
Home = new JPanel();
Home.setBackground(new Color(255, 250, 250));
Home.setBorder(new LineBorder(Color.DARK_GRAY, 1, true));
setContentPane(Home);
Home.setLayout(null);
JButton btnNewButton = new JButton("Data Entry login");
btnNewButton.setFont(new Font("Tahoma", Font.PLAIN, 14));
btnNewButton.setForeground(new Color(0, 0, 0));
btnNewButton.setBackground(UIManager.getColor("Menu.selectionBackground"));
btnNewButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
Home.setVisible(false);
setContentPane(DEL);
setLayout(null);
}
});
btnNewButton.setBounds(44, 214, 204, 61);
Home.add(btnNewButton);
}
}
Calling this JPanel which works
import java.awt.EventQueue;
public class Dataentrylog extends JPanel {
public Dataentrylog() {
setBounds(100, 100, 618, 373);
setBackground(new Color(255, 250, 250));
setBorder(new LineBorder(Color.DARK_GRAY, 1, true));
setLayout(null);
DEadmin DEA = new Deadmin();
final JButton btnSignIn = new JButton("Sign in");
btnSignIn.setFont(new Font("Tahoma", Font.PLAIN, 14));
btnSignIn.setBackground(UIManager.getColor("EditorPane.selectionBackground"));
btnSignIn.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
}
});
btnSignIn.setBounds(226, 282, 153, 52);
add(btnSignIn);
}
}
While this works if I try an call another JPanel from Dataentry log the JFrame is blank. What can I do to call another JPanel? Any help would be great. Also, I know that layoutmanagers are the norm but for what I had to do I wasn't able to find anything that worked so I choose to use null despite my best judgement. THANKS!
Intialization of Dataentrylog should be like this
final Dataentrylog DEL = new Dataentrylog(this);
we have to pass the parent jframe.
public class Dataentrylog extends JPanel {
public Dataentrylog(final JFrame parent ) {
setBounds(100, 100, 618, 373);
setBackground(new Color(255, 250, 250));
setBorder(new LineBorder(Color.DARK_GRAY, 1, true));
final JButton btnSignIn = new JButton("Sign in");
btnSignIn.setFont(new Font("Tahoma", Font.PLAIN, 14));
btnSignIn.setBackground(UIManager.getColor("EditorPane.selectionBackground"));
btnSignIn.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
setVisible(false);
JPanel panel = new JPanel();
panel.add(new JButton("Solved"));
parent.setContentPane(panel);
}
});
btnSignIn.setBounds(226, 282, 153, 52);
add(btnSignIn);
}
}
