Swing/AWT/SWT :: Frame And Panels
Nov 30, 2014
I wrote the following code to get a frame,button in south and a red color circle,which i got.In the "actionPerformed" method i wrote "setContentPane(mp2)" thinking it would put another panel on the frame with a blue circle but when i pushed the button,the button got stuck and the circled did not change.
import java.io.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class Fra implements ActionListener
{
MyPanel2 mp2;
JFrame frame;
JButton button;
public static void main(String[] args)
[Code] .....

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 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 cannot get my panels to appear in my GUI when I run my program. There is probably a really simple fix for this but it is taking me hours. This program is a working progress and I have just included two classes out of five. That should be adequate to diag my problem.
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class OrderCalc extends JFrame
{
private final int WINDOW_WIDTH = 200;
private final int WINDOW_HEIGHT = 200;
[Code]...

The question is when I hit the maximize button on the JFrame my panel instantly goes to the top left corner of the JFrame. Is it possible to center the panel inside the JFrame, when the maximize button is pushed? I am familiar with push and grow that MigLayout uses but this isn't exactly what I need. I don't want several textFields to span the screen. Instead I would rather have the panel centered.
This is just a sample project to test out the MigLayout API

Is it good practice to create a inner class for layered panels with lots of components? In my opinion this makes the code easier to read and a lot less clustered.

one of the java swing challenge I am facing. Problem statement: there are two JPanels panel 1 and panel 2 placed on a JFrame one below the other as panel 2 below panel 1. Now, I need to put a JButton in any one of the panels such that this JButton displays half in panel 1 and half in panel 2.

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;
[Code] .....

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 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 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();

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 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 {
private static final long serialVersionUID = 1L;

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'm getting the co-ords of the mouse clicks but no message when the click is inside the box
import java.awt.*;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
/*
Experiment 04 was successful. So now (Experiment 05) I must try and see if I can identify mouse clicks that occur within the rectangle.

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) },

I created a instance of a class AddItemView, inside StartUpMenuController. I then passed it into the class, the main method is below showing that as well. However when I do this:
else if(e.getSource()==menu.addBtn)
{
new addItem();
}
I get an error, little red line on the bottom of the text. I am testing the frame at the moment to make sure it is what I want before I move on to the Controller side of it. I just want to display it and go from there.
package mainMenu.Home.DataBase;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import addItemBtn.Home.DataBase.AddItemView;
public class StartUpMenuController
{
StartUpMenu menu;
AddItemView addItem;
[code]...
Not sure if this is the issue but the class I am making a new instance of is in a different package. I imported the package though.
