Swing/AWT/SWT :: Not Able To See Network Activity In JFrame

Jun 1, 2014

I am trying to develop an application which will be showing a TimeSeries graph(related library JFreeChart) displaying network activity related to a particular network interface embedded in a JFrame.I have created a JPopUpMenu which is having containing a list of JMenuItems showing network interfaces as their String values.Menu is popping up correctly

Further I am selecting a JMenuItem related to a particular network interface to show network activity in TimeSeries graph.On selecting a JMenuItem I can see that graph is moving on constantly but not able to see any network activity.

Pasted the code below :

package com.ankit.analyser;
import java.awt.BorderLayout;
import java.awt.Component;
import java.awt.EventQueue;
import java.awt.FlowLayout;
import java.awt.Window;
import javax.swing.JFrame;

[Code] .....

Further I can see that packetArrived method of PacketListener is not being overridden by class PacketHandler as I am not able to see data packets on console and static list in main class is also empty.

Swing/AWT/SWT :: Program That Record And Rerun Network Traffic

Sep 21, 2014

I have a program that records and reruns network traffic. It was developed in C and runs in my case under Windows 7 Professional but will run almost anywhere. I have observed a lack of stability.

First I have a JAVA stand alone GUI program that runs the program as follows:

g11_bttn_start_script_capture.addSelectionListener(new SelectionAdapter() {
@Override
public void widgetSelected(SelectionEvent e) {

URI uri = null;
URL url = null;
String tempstr = "";
tempstr = "-s " + g11_txt_PATH_portnumber.getText() + " " + g11_txt_scriptname.getText() + ".both";

[Code] ....

Basically it launches the executable t3drive, hangs arounf so it gets a chance to start, and then connect to it via the embedded browser.

It frequently works, sometimes launches in the browser but then freezes, and sometimes fails to start at all.

t3drive works 100% of the time if I run it under cygwin and I can reliably connect to it using any browser.

Why this might not be stable? Just looking for a direction of what to try next.

Eclipse Android - How To Go From 2nd Activity To 3rd Using Buttons

Feb 8, 2015

I didn't see anything specific to Android. I am a very basic beginner when it comes to JAVA and Android programming.

The app is a very simple comic strip viewer that views 3 panels of a comic strip one at a time. My problem is going from a second activity to another. I can go from the main activity to the second fine but when I press the next button to go from the second activity to the third nothing happens. I have tried a few different things but end up with either nothing happening or the app crashes.

Here is my MainActivity Code:

package net.androidbootcamp.comicapp;
import android.support.v7.app.ActionBarActivity;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

[Code]...

Here is the code for the second panel:

package net.androidbootcamp.comicapp;
import android.app.Activity;
import android.os.Bundle;
public class Panel2 extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {

[Code]...

Here is the code for Panel 3:

package net.androidbootcamp.comicapp;
import android.app.Activity;
import android.os.Bundle;
public class Panel3 extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {

[Code]...

And here is the manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="[URL].."
package="net.androidbootcamp.comicapp"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk

[Code]...

I am sure it is something very simple but I am not sure what it could be.

groupedFeeds ArrayList (id=831963150464)
array Object[12] (id=831963153088)
[0] GroupedFeed (id=831963152968)
category "Women's Golf" (id=831962986192)
feeds ArrayList (id=831963152992)
[1] GroupedFeed (id=831963153592)

[Code]...

I have here my Main method where I have to pass data to each of my sports(activities). I tried to create a for loop and then pass result to my sport(activity) but I'm doing something wrong and can not get that work. Here is my code:

//and then pass it to gfResult. }
public boolean onChildClick(ExpandableListView parent,
android.view.View v, int groupPosition, int childPosition,
long id) {
switch (groupPosition)

Green Bottles Activity - Printing Lyrics Of Song

Feb 23, 2014

I need to write up a code that will print the lyrics of the Green Bottles song. So it will ask the user to input a number and it will use that number to print the lyrics and then count down from that number. For example, user enters the number 5, the program will run and display:

"5 green bottles, hanging on the wall

5 green bottles hanging on the wall

and if one green bottles should fall

there will be 4 green bottles hanging on the wall

4 green bottles, hanging on the wall...." and so on.

So far I have managed to write a code that will display the number that is entered but I cant figure out how to subtract the number by 1 to continue it. My code so far:

import java.util.Scanner;
public class SomeJavaCode
{
public static void main(String[] args)
{
System.out.println("How many bottles to start with?");

[Code] ....

How to code it so that it substracts the number and repeats the rhyme till 0.

Swing/AWT/SWT :: Add A Rectangle To JFrame?

Apr 13, 2014

Is there a way to simply slap a rectangle into a JPanel (make it appear) with out creating an inner Class or helper Method, all within "Main"? And if not, why?

Making a JFrame is easy.

Adding a JPanel is a snap.

import javax.swing.JFrame;
import javax.swing.JPanel;
public class TheJFrame {
public static void main(String[] args) {

Swing/AWT/SWT :: Combining Two JFrames Into One JFrame?

Mar 20, 2014

All I need to do is show in just one JFrame the two combined JFrames. One JFrame namely leftPanel will appear to the left or west and the other namely rightPanel to the right or east using BorderLayout. I already did creating them first as JPanels or as internal classes and subsetted them in one JFrame but that didn't work because it looked messy. And now I've created them as two separate JFrames, compiled separately, and tried to subset them as one in the JFrame. I didn't add any functionality to this program because all I intend to do is to show those two JFrames together in one JFrame. Here's the code:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class dirtyIceCream extends JFrame {
leftPanel westPanel;
rightPanel eastPanel;
public dirtyIceCream()

[code].....

What am I missing or did I code anything wrong here? Or should I use NetBeans IDE for anything as complicated as this?

Swing/AWT/SWT :: Setting Size Of JFrame

May 26, 2014

I am rather new to Swing, and I am building a game right now in which I need to display a pop-up window as a reminder for what commands exist within the game. I created a class extending JFrame for this and added all the information I need. However, for some reason, no matter how many different ways I try to set the size of this window (setSize(w, h), pack(), using a different layout, adding the compnents to a JPanel first and setting the preffered size of that, then adding the JPanel to the JFrame), it doesn't work. Instead of a window of my requested size, I get a tiny, maybe 100 x 100 pixel window that needs to be resized in order for its contents to be visible.

import java.awt.FlowLayout;
import java.awt.Font;
import java.awt.GridLayout;
import java.awt.Toolkit;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

Swing/AWT/SWT :: Put A Web Page In JFrame Application

Apr 16, 2014

I need to put a Web Page in my JFrame application , I got a lot codes on the internet and could implement without problems , but the problem is that this code has an ugly page as hell, with colored all wrong and with a very poor quality , one of code I used was this :

* import javax.swing . ;

{ public class SwingWebPage
    public static void main ( String args [ ] ) throws Exception {
        JEditorPane website = new JEditorPane ( " http://www.google.com/ " ) ;
        website.setEditable ( false) ;

[code]...

If you test , you'll see that the page is displayed in the JFrame is horrible.

Swing/AWT/SWT :: Buttons Not Showing On JFrame

Aug 30, 2014

This is right from a book I'm reading but it doesn't work. The problem is to write an application that lets you determine the integer value returned by the InputEvent method getModifiers() when you click your left, right, or middle mouse button on a JFrame.

This is the code copied directly from the book. What is missing:

import java.awt.event.InputEvent;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.JFrame;
public class JLeftOrRight {

Swing/AWT/SWT :: Adding ContentPane To JFrame

Apr 18, 2014

The program loads, but nothing shows. I did some research and saw that I needed to set the JFrame to visible at the bottom of the frame section. I made the change, but it still does not show anything. Do I need to add everything that I added to the content pane to the frame? From my understanding you add elements to the panel, the panel to the contentPane, then the pane to the frame...

How do I find the dimensions of this JFrame in its extended state though? I tried this.getSize().Height , this getSize().getHeight() and this.getHeight()? None of them work because they just return a value of 0. And what is the difference in all these statements in terms of what they do?
