Gui Help ( toolbar )
Greetings,
Ive came across problems while doing a tutorial work piece.
i've to design a toobar ( yup a JToolBar ) with 5 buttons inside it, that will do certain functions for a JSlider.( set them at certain values )
Its simple enough to go and write 5 buttons into my code, but thats not wot ive to do.
The idea is that you will
develop one button that is customisable at design time to have one of 5 different
appearances. Developing 5 separate buttons is NOT an acceptable solution.
Is this even possible? ( pls note the 5 different appearances are Symbals )
Problem: Placing 5 buttons inside a JToolBar, and positing it under my created JSlider
// bob smith
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class Testing extends JFrame
int min = 40;
int max = 180;
int value = min;
JSlider slider = new JSlider(min,max,value);
MyUI ui = new MyUI(slider);
int tw,sw,startGap;
public Testing(){
setSize(250,100);
setLocation(400,200);
setDefaultCloseOperation(EXIT_ON_CLOSE);
slider.setUI(ui);
slider.addMouseListener(new MouseAdapter(){
public void mousePressed(MouseEvent me)
slider.setValue(min+(max-min)*(me.getX()-startGap)/tw);
slider.setMajorTickSpacing(20);
slider.setMinorTickSpacing(10);
slider.setPaintTicks(true);
slider.setPaintLabels(true);
getContentPane().add(slider);
setVisible(true);
tw = ui.getTrackWidth();
sw = slider.getWidth();
startGap = (sw-tw)/2;
public static void main(String args[]){new Testing();}
class MyUI extends javax.swing.plaf.basic.BasicSliderUI
public MyUI(JSlider js)
super(js);
public int getTrackWidth()
return (int)((Rectangle)trackRect).getWidth();
}Any help or guidance AT all, would be amazing :)
Thanks!

Portal w/SAP GUI; Help -- Application Help causes all windows be destroyed
Hello All -
I have a user who has portal windows (IE) open in the portal, multiple sessions. When he has a SAP GUI transaction in the application content area and selects the SAP GUI 'Help' --> 'Application Help' link, all the session windows are closed, and the primary goes to SAP help.
This destroys what the user was working on.
My computer does not do this, even when that user is logged in on my computer.
Any ideas?Hi,
Your requirements are not 100% clear. In your message you say you are looking for SNC between SAP GUI and SAP ABAP, but the help page you posted a link for is not related to this, but explains how to use SNC for CPIC.
If you are looking to use SNC for authenticating users of SAP GUI to SAP ABAP, then you have a number of options. If your SAP ABAP server is on Windows then SAP have a library which can be obtained for no cost to give you basic SSO using Active Directory authentication (aka Kerberos). If your SAP application server is on Unix or Linux, then you can look on SAP EcoHub for third party SAP certified products which provide this functionality. SAP have also just launched a new product which has some functionality for SAP GUI SSO, but this is not free.
Please let me know if you have any more questions or need clarification.
Thanks,

I am in need of serious GUI help... can someone save me please?? :(! ! !
Hello people..
I need to write a program to let users to design a GUI as they want. They can add a swing or awt component to a panel by choosing options from menu or toolbar. Obviously they can see what they have at runtime.
1.) I don't know how to display these components at runtime.
2.) how do i automatically add code, corresponding to the components being added to the panel, to a text file?
3.) and how do i save the text file and graphical design of the GUI together, which will allow users to return to the unfinished GUI, hence redisplaying the graphical design and text file of the code simultaneously?
4.) how can i delete a component, thus removing the corresponding code??
help would be very very very much appreciated..
thanx in advance... :)This is somehow a very very very complicated task !
Visit www.visaj.com,and here you will find a tool for building a GUI ,may be you get some idea. -
Both side chatting with simple GUI ,,helps pls?
guys I'm Java application programmer i don't have well knowledge in network programing ,,my question ,,,from where should i start to design a simple GUI client*s* server chat program ,i mean some thing like simple yahoo messenger the program should include also adding contact and make that contact appears ON if he login or OFF if he sign out like red color for ON-line contact and and white color for off-line contact ...........
another thing that chat system should include shared folder all the contact can enter it and upload file or download file ...
please guys i run to you to help me i have 2 weeks only to do that thing please don't let me down i need your help ....TIPS,code,any thing full code :) ,,any thing will be really appreciated .
guys for more information the program includes only the chat of course its both sides chat between the clients and these is no conference room
or audio or video nothing ,,just text only nothing else except the folder shearing service and the colors of the contacts for login or not .
guys once more help me give me codes or any thing useful i count on you guys.
thx a lot in advance

Dude , u r right ,,,but still its simple GUI issueI'm not sure why you are getting this impression. It's not a simple "GUI issue." Yes, you can simply create the GUI for this, but will it be functional? No. Furthermore, if it was so simple, why are you posting asking for help?
For an instant message chat program, in addition to GUI programming, you need to know how client / server systems work and you need to implement one. A server should be running on one system and the client(s) will connect to it. The server usually maintains the buddy list and passes the messages to/from different clients. This presents several problems that you will need to solve:
1. How will you develop a protocol between the client / server for communication?
2. How will you authenticate users?
3. How will you maintain the buddy list on the server (data structure, database, file)?
4. How will you pass messages from one client to another (simple string message, serialized data object, etc.)?
5. etc.
Now, I'm not saying this is "impossible" so please don't take it that way. I'm simply trying to help you realize that there are a lot of factors to consider when developing this type of application.

and for the "FTP?" ,,,its folder shearing as i said earlier every one of your friends can access it not FTP .....Talking about "folder sharing" is a whole other issue. What I meant by saying "FTP?" is, how do you plan on implementing "folder sharing" remotely? One option is FTP. How would you do it?

I'm working on a big GUI, using NetBeans since it simplified the initial container design... but now I need to link all the components to actions and events... which I'm not very experienced with.
I made a dummy GUI that does similar, but far fewer functions like my real project. Can someone help me design the actions/events for this little dummy gui, and explain how they work, so I can use that as a guide...?
The dummy project has two java files. A Scan class (Scan.java) will be used to parse a 'patient' text file, and create a String with info from that file (Scan.patient), as well as store the original pathname (Scan.path).
http://deviantone.com/javagui/Scan.java
You can create a Scan object by giving the constructor a File or String (file path) argument. You can then call the patient or path vars. The dummy 3 line patient file:
http://deviantone.com/javagui/dummy.txt
Now the hard part, the GUI from NetBeans... the syntax is a little bloated since it's machine generated, but shouldn't be too hard to figure out.
http://deviantone.com/javagui/dummyGui.java
The GUI is meant to parse whatever text file opened (for the purposes of this dummy gui, only dummy.txt will ever be browsed to, since the program can handle only 3 lines) into C:\output.txt (which you can create and leave blank beforehand).
What I need:
(1) The Open button (JButton openButton) needs to call a file chooser, where a user can browse to our dummy text file. dummyGui.java should then make a Scan object using this file.
(2) Once opened, the file path should appear in the JLabel pathLabel (you can use another gui component instead of a JLabel if you want, I just didn't know what would be the appropriate one for this sort of operation)
(3) You can select Yes/No or input some text into the combo box (JComboBox statusCombo) as well as input stuff into a text field, let's say a date (JTextField dateField). This information will also be written into output.txt
(4) Once you hit the Write button, Scan.patient, and the contents of statusCombo and dateField should be written into output.txt (it doesn't matter what line contains what, for simplicity maybe make statusCombo first, then dateField, then Scan.patient which is 2 lines)... I just need to see how to make a button do such an operation using another Object (Scan) as well as user input...
So far, I have looked through the API and File Chooser examples, and I've added the following to my code:
- instance variable to the dummyGui.java: File file; for the file that file chooser will get.
- also added openButton.addActionListener(this); to the initComponents() method.
- and another method:
public void actionPerformed(ActionEvent e) {
if(e.getSource() == openButton){
JFileChooser chooser = new JFileChooser();
int returnVal = chooser.showOpenDialog(dummyGui.this);
if(returnVal == JFileChooser.APPROVE_OPTION) {
file = chooser.getSelectedFile();
}But when I run the GUI, and hit Open, the button gets pressed in and then the window freezes while no file browser shows ... =/Don't use an IDE to generate your code, you don't learn anything.
Read the [url http://java.sun.com/docs/books/tutorial/uiswing/TOC.html]Swing tutorial. It gives sample programs on using the various Swing components. -
Unix Ate My OSX GUI Help Please
Hi All,
I have the darndest problem . I have a G4 AGP Powermac running OSX10.4.11. Processors are dual giga designs 1.8 ghz. One day I shut my Mac down as usual. The next day I start up and I get a gray apple screen with the rosette. The screen changes to blue,After a minute or so I get a black screen and welcome to darwin! There is a login and password which appear. I can login and it accepts my password, I receive my name with a dollar sign after it. I do not want to be there. I want to be in the non unix world of the uninformed typical GUI user. How do I get out of the shell and into my nice safe GUI interface of Tiger? I know of no issues that put me there. I have done some research into Unix and have used the most basic of commands. Help, info, exit, list. I admit I am totally lost.
So, any help would be greatly appreciated as all of my important stuff, pics music movies,etc. is on this computer. I have another internal hard drive in the G4 which is my backup, but am unable to access it at this time. It has no operating system on it.
Any help would be appreciated.

BillI doubt this is just as simple as that. Ordinarily the OS wouldn't boot to single user mode unless a) you held down a specific combination of keys at boot, or b) there's some problem affecting the normal boot problem.
I suspect the latter.
You should look carefully at the messages on screen. There should be something there that gives you a hint as to what's wrong (most likely a problem with the boot volume). It should also give hints on how to fix the problem using fsck. -

Can someone help me find a link, book, tutorial or anything along those lines that can help me understand building a GUI in Java? Thanks, Jeremy
When I was about to create my first GUI I used an IDE with "visual" capabilities. You design the GUI by using drag-and-drop and filling in tables, and then the IDE generates the code automatically for you. I found this helpful because Swing is so complex and in this way you get your options presented to you and you can study the generated code.

Hey guys I'm looking at working on java games further on down the track so I've just started working with java and some TCP clients and servers, I've come here to find some very useful information and now switched to Eclipse rather then Jcreator because I read somewhere it has a plugin for a GUi.
I'm working on a TCP client gui and at the moment this is my client's java code which works with the current server I have, As I said before I'm only just starting on java and this has been giving me a head ache for a couple of days now and I'm hoping someone can help me. The problem is with the line NetworkClient nc = new NetworkClient(args[0]); any answer as to whats wrong and a example of how to fix it would be great. Cheers in advance.
NetworkClient Code
import java.io.OutputStream;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.BufferedReader;
import java.io.PrintStream;
import java.net.Socket;
import java.util.Scanner;
import java.io.File;
public class NetworkClient {
private final int PORT = 2008;
private Socket sock;
private BufferedReader reader;
private Scanner console;
private PrintStream writer;
public static void main (String[]args)throws Exception {
new NetworkClient();
public NetworkClient()throws Exception {
sock = new Socket("localhost",PORT);
InputStream in = sock.getInputStream();
OutputStream out = sock.getOutputStream();
reader = new BufferedReader(new InputStreamReader(in));
writer = new PrintStream(out);
console = new Scanner(System.in);
System.out.println("Enter a line of text");
while(console.hasNext()) {
String line = console.nextLine();
writer.println(line);
if(line.matches("QUIT")) {
writer.close();
System.exit(0);
String response = reader.readLine();
System.out.println("Response from server was: " + response);
if(line.matches("LIST")) {
int number = new Integer(response);
for (int n = 0; n <number;n++) {
response = reader.readLine();
System.out.println("Response from server was: " + response);
System.out.println("Enter a line of text");
public String doEcho(String line)throws Exception {
writer.println("Response from server was: " + line);
String response = reader.readLine();
return response;
UserInterface Code
import java.util.Scanner;
public class UserInterface {
private Scanner console;
private NetworkClient netClient;
public static void main(String[] args) throws Exception {
if (args.length != 1) {
System.err.println("Usage: Client address");
System.exit(1);
NetworkClient nc = new NetworkClient(args[0]);
new UserInterface(nc);
public UserInterface(NetworkClient client) throws Exception {
netClient = client;
console = new Scanner(System.in);
System.out.println("Enter a line of text");
while (console.hasNext()) {
String line = console.nextLine();
System.out.println("Request was: " + line);
String response = netClient.doEcho(line);
System.out.println("Response from server was: " + response);
System.out.println("Enter a line of text");
GUI Code
import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.JTextArea;
import java.awt.BorderLayout;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
public class GraphicalUserInterface extends JFrame
implements ActionListener {
private final int HEIGHT = 10;
private final int WIDTH = 40;
private NetworkClient netClient;
JTextField textField = new JTextField(WIDTH);
JTextArea textArea = new JTextArea(HEIGHT, WIDTH);
public static void main(String[] args) throws Exception {
if (args.length != 1) {
System.err.println("Usage: Client address");
System.exit(1);
NetworkClient nc = new NetworkClient(args[0]);
new GraphicalUserInterface(nc);
public GraphicalUserInterface(NetworkClient client) throws Exception {
netClient = client;
setLayout(new BorderLayout());
add(textField, BorderLayout.NORTH);
add(textArea, BorderLayout.CENTER);
textField.addActionListener(this);
pack();
setVisible(true);
public void actionPerformed(ActionEvent evt) {
String text = textField.getText();
if (textArea.getLineCount() > HEIGHT) {
textArea.setText("");
try {
textArea.append(netClient.doEcho(text) + '\n');
} catch(Exception e) {
// ignore
textField.setText("");

No not yet but I'm wanting to hand this in before the exam which is quite close, But you must realize that this is your urgency, not ours. None of the volunteers here like to be pressured, and so something marked ** urgent ** is actually often marked for flames and has the exact opposite effect: many here will simply refuse to answer anything labeled this way. Just something to remember next time.
and to put it quite blunty our teacher anit great and really doesn't give examples or anything in fact we asked him something simple and he just said "oh I forgot" with that we ended up working it out ourselves.Oh, don't go there. We've heard this all the time, and regardless if it's true or not, your education is ultimately your responsibility. No one will accept your passing blame to someone else, period. Accept your own responsibility and get to work, show your effort, and possibly someone here will put in the effort to help you.
My client works with the server I have thats for sure they problem is getting the GUI and the UserInterface to work with my client now these two were given to us by the teacher so I've been trying to work it our for sometime as I'm not good at java at all and just want to get a example and get it finished so I may continue on with my exams.What specific question do you have? Broad questions and claims of misunderstanding often get ignored. Specific questions are often answered. Requests for code are often flamed.
The error resides in NetworkClient nc = new NetworkClient(args[0]); in both the UserInterface and in the GUI but I believe the problem is public NetworkClient()throws Exception with a little help of a friend so the error is the Constructor for my NetworkClient class, You appear to be calling a constructor that simply doesn't exist. I don't see a constructor in the NetworkClient class that accepts and array of Strings as a parameter. If there isn't one in another version of this class that wasn't posted, then you have one of two choices: either use a correct constructor (my bet) or create a new constructor for the class. Why are you trying to pass this parameter in the first place? Especially in the GUI program?
Sorry if you believe its not urgent but it is to me.We believe that it's urgent to you, but you must believe that this means little to us. Sorry, but that's how it is.
Good luck. -

Hi! I posted the same question just the other day so I am glad to help.
To make it exit the window the command is System.exit(0) so it could look like this.
public void actionPerformed(ActionEvent evt) {
System.exit(0);
p.s. Maybe the scrollbar problem is with the size of the frame? Im not sure I was just looking through for Duke Dollar questions to answer an found u. If you need help DDs do work by the way.(lotsa people just make a nu account tho)

InDesign CS4 Help--Toolbar not showing, can't type or do anything.
So I downloaded the trial version of Indesign CS4 on my computer, and when I opened it there was no toolbar, and I basically cannot type anything on it etc. . .
I looked through some older posts on the forums and people suggested uninstalling it and then reinstalling. My only fear is that since this is a trial version I thought that after uninstalling the program it wouldn't let me reinstall the program since I already had my free trial.
Does anyone have any other suggest on how to fix this or know if uninstalling it will still let me use the trial version when I reinstall it.
Thank you very much!kirklande wrote:
This may sound stupid, but I couldn't find the TAB key?
The Tab key is on the upper left side if the keyboard. That's the key you use for indenting a line in Word, or aligning columns in a free-typed table, or switching fields in a spreadsheet or your browser.
Unfortunatley, that isn't likely to be the issue given the rest of your description. It sounds like you have a failed installation, and I wish I could tell you that you can try again, but I honestly don't know. For previous versions that was not possible without reformattinig the hard drive.
There were some issues of this type that popped up on some older hardware that didn't support certain instructions. Those probelms were fixed, I think, with the 6.0.2 or 6.0.3 patch. You could try downloading the update and see if it will run.
What OS are you using? Do you have a way, such as System Restore on Windows, to go back to before you installed the trial? If so that would be a possibility for trying to reinstall. make sure you disable any anti-virus or other security software before do a new installation, and though I haven't seen any problems personally installing CS4 with other stuff running, you might want to diable anything else that isn't strictly required for you system to operate. Lots of things, like the add-on browser toolbars adn instant messengers were know to interfere with CS3 installations, but I don't use that stuff on my systems so I have no experience one way or the other withthem in CS4.

Hi,
I have a requirement like if i execute the print program for smartforms printer window will appear.in printer window if i choose print preview in next layout preview window print icon and menu is coming.
I want to disable the print icon and print menu.
And If print option choosen by user from printr window.I have to update some records to database. Is it possible?
Thanks
Regards,
NandhaUsing these strucutres 'SSFCTRLOP' 'SSFCRESOP' 'SSFCRESCL' 'SSFCOMPOP' you can do modifications to ur print icon, etc.., try to implement them.
Regarding when u click the print window you can update the records also. generally when u print the smartform or download it in pdf form the 'nast' table is updated to know whether the file has been printed or not. like that you can do the same for updating various records.
Reward points if its helps.

Powershell Toolbar GUI "Docking" toolbar
Hi Guys,
I have created a powershell script, that is a Toolbar with quick links to programs and to run admin tasks for the network (IE remote assistance, MSTSC, remotely log off etc). I have worked out how to make the Toolbar on top of all other windows. But I was
wondering if it was possible to make this toolbar 'Dock" to the top of screen? So when the toolbar is open and a window is maximized the top of the window is not cut off.
I dont know if this possible in powershell or not
Thank youIt probably is, but I am not sure just yet on how to accomplish it (will need to research). In the meantime, you could set the TopMost property of the control to 'True' and this will ensure that it always remains in front of all other windows if you have
other things being displayed.
