This code shows focus gained before the button is clicked

I want the GUI to show "focus gained" when the user clicks on the button and
"focus lost" when clicking anywhere else. But it always shows "focus gained".
Main Code:
import java.awt.*;
import java.awt.event.FocusEvent;
import java.awt.event.FocusListener;
import javax.swing.*;
public class focuslistener extends JFrame {
private Container c;
private JButton jb1;
private Font f;
private JTextArea ta1;
focuslistener() {
inticompo();
}
public void inticompo() {
c = this.getContentPane();
c.setBackground(Color.yellow);
c.setLayout(null);
f = new Font("Arial", Font.ITALIC + Font.BOLD, 18);
jb1 = new JButton("Clicked");
jb1.setBounds(50, 10, 250, 80);
jb1.setForeground(Color.red);
jb1.setBackground(Color.blue);
jb1.setFont(f);
c.add(jb1);
ta1 = new JTextArea();
ta1.setFont(f);
ta1.setBounds(10, 110, 400, 300);
ta1.setForeground(Color.black);
ta1.setBackground(Color.red);
c.add(ta1);
jb1.addFocusListener(new FocusListener() {
#Override
public void focusGained(FocusEvent fe) {
ta1.setText("focus Gained");
}
#Override
public void focusLost(FocusEvent fe) {
ta1.setText("focus Lost");
}
});
}
public static void main(String[] args) {
focuslistener a = new focuslistener();
a.setVisible(true);
a.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
a.setBounds(50, 100, 500, 500);
a.setTitle("hello");
}
}

JPanel won't show up in JFrame

Why does my JPanel not show in JFrame after button is clicked.
There's my code:
import java.awt.EventQueue;
import javax.swing.JFrame;
import javax.swing.JList;
import javax.swing.DefaultListModel;
import javax.swing.AbstractListModel;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
import javax.swing.JButton;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.JPanel;
public class Main {
private JFrame frame;
private JTable table;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Main window = new Main();
window.frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the application.
*/
public Main() {
initialize();
}
/**
* Initialize the contents of the frame.
*/
private void initialize() {
frame = new JFrame();
frame.setResizable(false);
frame.setBounds(100, 100, 450, 300);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(null);
table = new JTable();
table.setModel(new DefaultTableModel(
new Object[][] {
{"1", "Marcin Zelek", "537573656"},
{"2", "Krzysztof Tomala", "324159103"},
{"3", "Zbigniew S", "324159104"},
},
new String[] {
"#", "Name", "Phone number"
}
));
table.getColumnModel().getColumn(1).setPreferredWidth(214);
table.getColumnModel().getColumn(2).setPreferredWidth(246);
table.setBounds(12, 103, 426, 185);
frame.getContentPane().add(table);
JButton btnDodajNowy = new JButton("Dodaj nowy");
btnDodajNowy.addMouseListener(new MouseAdapter() {
#Override
public void mouseReleased(MouseEvent arg0) {
JPanel panel = new JPanel(null);// Creating the JPanel
panel.setBounds(0, 243, 286, 150);
panel.setVisible(true);
JButton button = new JButton("New button");
button.setBounds(12, 12, 117, 25);
panel.add(button);
frame.getContentPane().add(panel);
}
});
btnDodajNowy.setBounds(12, 30, 117, 25);
frame.getContentPane().add(btnDodajNowy);
JButton btnUsuZaznaczone = new JButton("Usuń zaznaczone");
btnUsuZaznaczone.addMouseListener(new MouseAdapter() {
#Override
public void mouseReleased(MouseEvent arg0) {
DefaultTableModel model = (DefaultTableModel) table.getModel();
int[] selection = table.getSelectedRows();
for (int i = 0; i < selection.length; i++)
{
model.removeRow(selection[i]-i);
}
}
});
btnUsuZaznaczone.setBounds(141, 30, 204, 25);
frame.getContentPane().add(btnUsuZaznaczone);
}
}
Thanks.

You should use actionListener instead:
btnDodajNowy.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
JPanel panel = new JPanel();// Creating the JPanel
panel.setBounds(0, 243, 286, 150);
JButton button = new JButton("New button");
button.setBounds(12, 12, 117, 25);
panel.add(button);
frame.getContentPane().add(panel);
frame.repaint();
}
});
and also:
You don't need to pass null as a parameter to the JPanel constructor
You might want to add a frame.repaint()
You don't need to set the JPanel to visible via setVisible().

If you looking to present the panel in same jframe where you added the button you probably should use CardLayout here is the link http://docs.oracle.com/javase/tutorial/uiswing/layout/card.html

It is being added, however, it is hiding below the JTable. The quickest fix is this:
public void mouseReleased(MouseEvent arg0) {
//...
panel.setBounds(0, 300, 286, 150); // 300 is on the y axis
//...
// then render the frame again:
frame.revalidate();
frame.repaint();
}
However, I suggest to rewrite it a little:
this.generalPanel = new JPanel();
frame.getContentPane().add(generalPanel);
...
generalPanel.add(table);
This way you'll get a good Layout for the topmost container.

how can i use a Jbutton in a class to trigger a panelSlider effect which is in a button actionPerformed in another class

how can i use a Jbutton in a class to trigger a panelSlider effect which is in a button actionPerformed in another class
Find the code here
public class programDisplay extends javax.swing.JPanel { /** * Creates new form programDisplay */
public programDisplay() {
initComponents();
}

here is an example for sliding effect of panel. you can take it as a reference and implement your requirement.
import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
import javax.swing.Timer;
public class SlidingPanel {
JPanel panel;
public void makeUI() {
panel = new JPanel();
panel.setBackground(Color.RED);
panel.setBounds(0, 0, 400, 400);
JButton button = new JButton("Click");
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
((JButton) e.getSource()).setEnabled(false);
new Timer(1, new ActionListener() {
public void actionPerformed(ActionEvent e) {
panel.setLocation(panel.getX() - 1, 0);
if (panel.getX() + panel.getWidth() == 0) {
((Timer) e.getSource()).stop();
System.out.println("Timer stopped");
}
}
}).start();
}
});
panel.add(button);
JFrame frame = new JFrame("Sliding Panel");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(400, 400);
frame.setLocationRelativeTo(null);
frame.setLayout(null);
frame.add(panel);
frame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
new SlidingPanel().makeUI();
}
});
}
}
UPDATE :
in HomePane.java
rightPane rPane = new rightPane();
JPanel lPane = new leftPane(rPane);
in leftPane.java
private rightPane rPane;
public leftPane(final rightPane rPane)
{
pane = new JPanel();
this.rPane = rPane;
staffLogin = new JButton("STAFF LOGIN");
adminLogin = new JButton("ADMIN LOGIN");
guestLogin = new JButton("GUEST LOGIN");
staffLogin.addActionListener(new ActionListener(){
#Override
public void actionPerformed(ActionEvent e)
{
rPane.trigerEvent();
}
});
this.setLayout(null);
this.add(staffLogin);
this.add(adminLogin);
this.add(guestLogin);
staffLogin.setFont(new Font("Serif", Font.BOLD, 20));
adminLogin.setFont(new Font("Serif", Font.BOLD, 20));
guestLogin.setFont(new Font("Serif", Font.BOLD, 20));
staffLogin.setBounds(20, 10, 200, 50);
adminLogin.setBounds(20, 75, 200, 50);
guestLogin.setBounds(20, 140, 200, 50);
this.setBorder(BorderFactory.createLineBorder(Color.BLUE));
pane.setBorder(BorderFactory.createLineBorder(Color.red));
}

My image disappear when i run jar file

well here are the classes i made..
package testdnevnik;
import javax.swing.JFrame;
public class Diary {
StartWindow startWindow = new StartWindow();

int n = 0;
public Diary() {
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

when i run the program from the NetBeans everything is ok,running perfectly,but when i click "Clean and Build Project" in NetBeans and run from the jar file in the folder,the background is white but the components added to the panel are fine,just the image for the background disappearing,why??

Why wont the submit button work on the GUI

I have created an ActionListener and the button but the button doesn't work.
The action listener is supposed to be integrated with the submit button, please help?
Code:
import javax.swing.*;
import javax.swing.event.DocumentListener;import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class Executer {
private JLabel lblCommand;
private JTextField txtEnter;
private JButton btNext, btPrevious, btSubmit;
private JPanel panel;
public static void main(String[] args) {
new Executer();
}
public Executer() {
JFrame frame = new JFrame("Script Executer");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(500,300);
frame.setVisible(true);
myPanel();
Text();
Fields();
Buttons();
frame.add(panel);
frame.setVisible(true);
}
public void myPanel() {
panel = new JPanel();
panel.setLayout(null);
}
public void Text() {
lblCommand = new JLabel("Enter Here");
lblCommand.setBounds(145, 100, 150, 20);
Font styleOne = new Font("Arial", Font.BOLD, 13);
lblCommand.setFont(styleOne);
panel.add(lblCommand);
}
public void Fields() {
txtEnter = new JTextField();
txtEnter.setBounds(230, 100, 120, 20);
panel.add(txtEnter);
}
public void Buttons() {
btNext = new JButton ("Next");
btNext.setBounds(300,215,100,20);
panel.add(btNext);
btPrevious = new JButton ("Previous");
btPrevious.setBounds(190,215,100,20);
panel.add(btPrevious);
btSubmit = new JButton("Submit");
btSubmit.setBounds(80,215,100,20);
panel.add(btSubmit);
btSubmit.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
String userEntered = txtEnter.getText();
if(userEntered.equalsIgnoreCase("yes"))
{
//run your script
}
}
});
}
}

Your code appears fine.
Enter a print statement and you can see it is working.
btSubmit.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
// here the click happend so you can check your Textfield
String userEntered = txtEnter.getText();
System.out.println("User enterd: " + userEntered);
if(userEntered.equalsIgnoreCase("yes"))
{
System.out.println("Entered Yes");
}
}
});
