Swing/AWT/SWT :: Jinternalframe Active Frame Different With Java 7?
Jun 24, 2014
I am in the progress of updating my code and re-testing after switching from Java 6 to Java 7. When I open multiple JInternalFrames in my application under java 6 I am used to closing the top most internal frame and having the frame immediately under it become the next active frame. When I run the same code under Java 7 I see a different behaviour in as much as when I close the last frame I opened, the next one to become active is the first one.
To illustrate this another way, lets say I open 5 internal frames, 1,2,3,4 & 5
In java 6 when I close frame 5, frame 4 becomes the active frame.
In java 7 when I close frame 5, frame 1 becomes the active frame.

I got a JFrame with its JDesktopPane, and opens a JInternalFrame at the beginning of the execution of the application. That's all fine.
And then, the first JInternalFrame opens another JInternalFrame in its maximum size, and that's when a simple JLabel that I got o the second internal it disapears. Why?

I'm having issues with providing focus to keyboard buttons when a JInternalFrame with keyboard buttons is called in my program. So for example when the program is started the attachment called signinscn.png is called.
This screen is a JDesktopPane which calls JPanel for its components.
From here a JInternalFrame containing the buttons ESC and F1 to F4 as seen in the attachment called signinscn.png is called.
I would like the buttons in my JInternalFrame to have focus such that when a user engages the equivalent keyboard button i.e. ESC or F1 to F4 WITHOUT clicking on the JInternalFrame the respective button's action listener kicks in. At the moment only after the user clicks on the JInternalFrame do the equivalent keyboard buttons respond.
Here's the constructor of my JInternalFrame and you can see how I handle the ESC keyboard button in the constructor of the JInternalFrame (but as I mentioned only after the user has engaged the JInternalFrame):
//!<
public AdminHomeJIFrame() {
super(null, false, // Resizable
false, // Closable
false, // Maximizable
false); // Iconifiable
BasicInternalFrameTitlePane titlePane =
(BasicInternalFrameTitlePane)((BasicInternalFrameUI)this.getUI()).getNorthPane();
[Code] ....

I am trying to make a 2d graphical animation using the java swing classes in order to make a frame. I had a basic version working when all of the code was under the main method, but when I moved some into another method it broke it. With y understanding of java my code should work as I create a variable of the method containing the code and then assign the size and exit button. However this causes many problems such as my BeaconFrame method informing me that it is unused when I have used it. Here is my code:
import javax.swing.*;
import java.awt.*;
public class BelishaBeacon {
public void BeaconFrame() {
JFrame frame = new JFrame();
JPanel panel1 = new JPanel();
[code]....

This program asks the user for their starting balance, number of deposits, and number of withdrawals for a month
Now, if the number of withdrawals goes over 4, it has to include a service charge of 1.00 for every withdrawal that was more than 4 (This works fine so far)
The problem I am having is this:
The subclass part of this program is supposed to determine whether an account is below 25. If it is, it should make the account inactive, until the account is 25 or more. The subclass will have a method that will override the super's setWithdrawal mehtod to make sure that no withdrawals will be made until that balance is 25 or more.
Then the setDeposit method in the subclass will also override the super's setDeposit method and make sure that the account is not inactive before any deposits are made. If the account was determined to be inactive at that time and the deposits that were added make it jump to 25 or more, than the account should be changed to active and then be allowed to call the super's method to set the deposit.
So...the issue I am having is the subclass trying to determine whether the balance is under 25 before it calls the super's version of that method where it will allow the user to take money out and when making deposits where it will determine if the account was inactive first before make it active while the deposits raise to 25 or above.
Here is my super class:
// This is an abstract class that will be used for its child class BankAccount
public abstract class BankAccount {
private double balance; // To hold the account balance for the month
private int numDeposit; // To hold the number of deposits for the month
protected int numWithdrawal; // To hold the number of withdrawals for the month
private double annualIR; // To hold the annual interest rate for the month
protected double monthlyServCharge; // To hold any service charge for the month
private double monthlyInterest;

I simply want to paint an image on my frame, just once each time the paint() method is called, but how to call the paint method in any good way. This is how it looks:
import java.awt.AWTException;
import java.awt.Dimension;
import java.awt.Graphics2D;
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
[Code] ....
I have a frame in another class, and from my assumption I need to somehow tell my paint method to paint on that specific frame right?

I am trying to call another swing frame from my current frame. And after calling second frame i dispose the current frame.
But while second frame coming on the screen, current frame gets dispose and second frame takes some seconds to appear on screen.
So its creating a bad flickering effect on screen and its not suitable for my application.
I want that first frame will call sencond frame and it will not look like second frame is called. I just want to cancel flickering effect.
Here is my source code.
1st Frame:
public class Welcome extends JFrame {
JFrame f;
JTextArea nameField,nameField1;
JLabel lable;

I have been doing a project of ERP solution using JAVA AWT FRAMES and MYSQL(for database purpose). Here there is an ADMIN portion, who has the authority to make PAYROLLS of individual employees. There is a Frame where individual employee details will be shown(like basic salary, HRA, no.of leaves, other allowances...etc) in text boxes.
Now what i want is to make a PDF file of that payroll, so that I can make a hardcopy of it. The idea is just like anyother online form fill-up, where at the end you submit and save (or export) as a PDF (or text file) document. But I mention that it is a stanalone project, not an online one (i think it doesn't matter though).
So the basic idea is how to make a PDF file by extracting the text field or choice contents from a frame in JAVA AWT.

I'm having trouble with this program. In my textbook it says "Write an application that displays a frame containing two panels. Each panel should contain two images (use four unique images - your choice). Fix the size of the first panel so that both of its images remain side by side. Allow the other panel to change size as needed. Experiment with the size of the window to see the images change orientation. Make sure you understand why the application behaves as it does". I successfully imported the images, but I can't find out anywhere how to allow the second panel to change size with the window.
import java.awt.*;
import javax.swing.*;
public class TwoPanels
{
public static void main(String[] args)
{
JFrame frame = new JFrame ("Embedded Images");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
ImageIcon iconOne = new ImageIcon ("glove.jpg");
ImageIcon iconTwo = new ImageIcon ("cleats.jpg");
ImageIcon iconThr = new ImageIcon ("bat.jpg");
ImageIcon iconFou = new ImageIcon ("baseball.jpg");

I have a Single Frame Application and I simply want to prompt the user with a dialog confirming they really want to close before they actually close the program, specifically when they click the X in the upper right. I THOUGHT it was like any other java application, with the slight added complexity of having to target the program-created-JFrame with: ".getApplication().getMainFrame()".
MyApp.getApplication().getMainFrame().setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
With that code, DO_NOTHING_ON_CLOSE is set on the JFrame, yet the program closes anyways. Which I don't understand.So I did some reading and found this: URL....That lead me to the configureWindow override, where I successfully tried this:
root.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
// write your code here
System.out.println("Window Closing");
}
});
But as far as I can tell that will only let me react to the window closing, not to the command to close it, where I could then kill the command in the dialog if they so "no I'm not ready to quit yet", if that makes sense. So, how to give a prompt before closing?I am using netbeans IDE to create this app - not sure if that is relevant, since maybe it is an oddity with the IDE and not Single Frame Applications.

I am writing a ComputerBaseTest application with Netbeans. I have each question on a panel and I want the questions(panels) to be switched, viewing the previous and the next question on a single frame, but I do not know how.
I only understand frame switching if each questn is to be on a frame but each score on each question (frame) do not sum up to give the overall score at the end of the test. Using multi-frame shows a sign of bad programming.

I am building a GUI application which consists of two panels "panel" and "panel1". "panel1" have a button "addTimer" when clicked it should add the "panel" to the frame if i gain click the button it should again add the "panel" without overlapping the previous "panel" rather it should be created below the previous "panel". If i click on the button "addTimer" n times it should add the panel n times. Along with this the frame size has to dynamically change depending on the number of panels produced. Below is the code i tried my level best to satisfy the above conditions.
package superTimerV2;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class SuperTimer extends JFrame {

In the method mouseClicked(MouseEvent me) the co-ords of the click are obtained.
* if they are within the confines of the rectangle rect, console output System.out.println("inside box") is displayed
* in either case the click co-ords are displayed in the console

I want to calculate the height of a dialog that contain only a table depending on how many rows that table it has so I'm using the cross multiplication rule.For example i check initially that my table is well fitting into the dialog(Without space at the bottom) for some value and after that i use the cross multiplication rule because data are dynamic.But unfortunately this rule does not solve the problem.What's the best rule for fitting a dynamic table inside a dialog or a frame? Here is my code.
public class FlowLayoutChangingGap {
public static void main(String[] args) {
// just for testing perpose but data are getting from database and it's dynamic
Object[][] data = {
{ "Kathy", "Smith", "Snowboarding", new Integer(5) },
{ "John", "Doe", "Rowing", new Integer(3) },

Is it possible to create a JInternalFrame class with additional public functions that can be called from the desktop? Here is some snippets of the code. This is the Internal Frame with the public functions added after the constructor.
public class Search_Ifr extends javax.swing.JInternalFrame {
/**
* Creates new form Search_Ifr

public Search_Ifr() {
initComponents();

The line " ifrSearch.setTabPaneIndex("tabCust");" is throwing a compile error that the method is not found.
