HI - TECH.....AWT GUI Problem
Hi everyone,
Im making an AWT gui (WOW!) for an application that I wrote and works (bigger WOW !) so for me this is
my "Ultimate Computer Program". Sadly, im stuck.
Hope someone can help here. Heres my problemo..
The first screen that has a textField and some buttons.
When I enter a ticket number in the text field and press the OK button, the String entered is used
as a parameter for an RMI method call.
This RMI call returns a Ticket object. This has loads of attributes I want to display
by calling the tickets accessor methods.
My Question is how can I do this using AWT?
You see, I may have just got the ticket object returned to me, but i dont know how to clear the screen
and print its attributes.
In essence what I have no clue to do are the following main things.....
*Clearing the screen in my little applet thingy so im no longer showing the intitial
screen in which the user enters the ticket number.
*Then Displaying various strings and numbers contained in the Ticket object t which i get by using my accessor methods......
For example say ive just had returned to me the Ticket object t,
And I want to print the string returned by the accessor t.getCustomer()
How would I do this?
Any Help here is greatly appreciated!
thanks
Well, if you have the text field and button in a panel and that panel is in the frame, you can remove the panel from the frame and put a new panel in it's place. And the new panel can be a class you could make that has several fields and takes your ticket object and displays the data in it.

To the original poster, cross-posting can frustrate anyone who tries to help you only to find out later that the same answer was given hours ago in a cross-posted thread. No one likes wasting their time, especially a volunteer. The polite thing to do would be to not do this, but if you feel that you absolutely must, to at least provide links in both cross-posts to each other.

Hi Joseph
We are using Forte 3.0 M2 on Solaris 5.8 The problem is with the push
buttons, After we grid the controls and they look intact in the NT
environment, but when we open the same window in SOlaris the controls are
far apart.Do you have any idea about this?

Hello vashundara,
please say which Version of Forte and which kind/version your UNIX OS is.
There are some problems on AIX V4.3.x (Motif 2.x) and older releasese of
Forte (up to Forte 3.M.x) and so on and it is necessary to look what it is.
Maybe it is possible for you to say which widgets are the problem.
Thanks forward

Hi
We are facing a strange problem when we try to port our application from NT
to UNIX. The problem is that the GUI doesnt come properly. As per my
knowledge gridding all the controls on the GUI shouldnot create this
problem, but inspite of this we are facing it. Did anyone comeacross this
situation?
Thanks in advance

Mutlithreading with GUI problem
hey guys,
I was working on some Socket programming assignment and encountered an intersting problem.
i am using Swing for GUI and Threads to communicate with clients.
My server GUi has a JButton("Start Server") to trigger the Server. or we can say.. it starts accepting connection( SocketObj = ServerSocketObj.accept() )
problem:
as soon as i press the only Button(i.e. StartServer Button) on my Server GUI. whole GUI freezes!
but Server is working... all updates on GUI are missing.. cant repaint components, etc. neither WindowClosing event , setDefaultCloseOperation()) is working.
i did some research.. found that swing components are not thread safe,
also found some close answers,, along the lines of.. Event Dispatch Thread, SwingUtilities.invokeLater(Runnable), SwingWorker class , but neither work or maybe i did not implement them properly..
Attachment contains my code for:
Server.java : Server class conatins main()
ServerGUI.java : gui for server.. called from Server Class
ClientHandler.java : Thread for handling clients.. also called from Serve class
Cleint.java : simple client to connect to server at localhost
Any sort of help would be highly obliged.
thanks in advance.

Hi everyone,
I have been trying to get this GUI built from the ground up and I have encountered a problem with the GridBag(exception error that the fields being added can not be done. Also, my method main seems to be off track, I have a working program which the display fields have been modified to display object and everything else is the same except that I can not get the GUI to run.
The following is the code and any suggestions as to what I can do to get this going will be appreciated. Thank you.

/*Beginning of the class type Inventory*/Hi Bryan,
I took your advice and decided to take a different approach to the problem I am having, I decided to stay somewhat with the basics with little knowledge I have about coding. I am new to this and I am trying to learn through the fire but it's getting hot so if you don't mind, can you tell me what I need to do to fix the error messages I am getting.
1. "else" without "if',
2. can't load my icon-a JPG
3. exception in thread amin
process complete.
4.Text area for displaying an iteration of the input
the code is not as long as the other one! any help will be appreciated. Also I am attaching the code to the GUI that does work but I can not seem to get the actionListener aspect to work. Thanks again.
//this one works and it serves as a model for what I am //trying to do in the fields. as well as designate a text area //where a each entry per iteration of input is displayed

Okay, Im trying to create a simple input/output menu. I'm trying to get the GUI portion wrapped up but it's kicking my but. The display is suppose to have one side with a text=Enter Weekly Hour, a text entry field and a enter button. The other side will be the display. I have built these and put them in there round about locations but I have two problems.
1. The text "enter weekly hour", text entry field and the enter button are suppose to be one on top of each other.
2. When I resize the screen down or up it cuts off or rearranges the area's different than the way they are suppose to be.
I know I have to bind the heights of the components by placing them into another BorderLayout-managed container. Which I thought I have done. Obviously I am missing something really simple.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class Ch14NestedPanels1 extends JFrame {
// Data Members

frame.setVisible(true);
// Constructors

public Ch14NestedPanels1() {
Container contentPane;
JPanel inputPanel;
JPanel listPanel;
JButton enterButton;
//set the frame properties
setSize (FRAME_WIDTH, FRAME_HEIGHT);
setTitle ("Program Ch14NestedPanels1");
setLocation (FRAME_X_ORIGIN, FRAME_Y_ORIGIN);
contentPane = getContentPane( );
contentPane.setLayout(new BorderLayout(5,5));
//Creates panel for entry items inputEntry,text, and enterButton
inputPanel = new JPanel();
inputPanel.setBorder(BorderFactory.createLoweredBevelBorder());
contentPane.add(inputPanel, BorderLayout.WEST);
//Creates text entry field
inputEntry = new JTextField(10);
inputPanel.add(inputEntry,BorderLayout.CENTER);
//Creates text label
text = new JLabel("Enter weekly hour");
inputPanel.add(text,BorderLayout.NORTH);
//Creates enter button
enterButton = new JButton("Enter");
inputPanel.add(enterButton,BorderLayout.SOUTH);
//Creates panel for list display
listPanel = new JPanel();
listPanel.setBorder(BorderFactory.createLoweredBevelBorder());
listPanel.add(list = new JLabel("This is where the list goes"));
contentPane.add(listPanel,BorderLayout.EAST);
setDefaultCloseOperation( EXIT_ON_CLOSE );Your basic code is like this:
inputPanel = new JPanel();
inputEntry = new JTextField(10);
inputPanel.add(inputEntry,BorderLayout.CENTER);
text = new JLabel("Enter weekly hour");
inputPanel.add(text,BorderLayout.NORTH);
enterButton = new JButton("Enter");
inputPanel.add(enterButton,BorderLayout.SOUTH);
By default when you create a JPanel it uses a FlowLayout. So when you add a component to the panel the components a layed out Left-to-Right.
Using BorderLayout.CENTER, NORTH, SOUTH is ignored by the FlowLayout manager.
You should be using:
JPanel inputPanel = new JPanel( new BorderLayout() );
Now when yo add component to your panel you can use the BorderLayout constraints. -
A GUI problem when using sockets
I have a problem with Client.java. it creates a socket to connect to a serversocket. I do this through the method "runClient()" .
the problem is that if I call runClient from an actionlistener add to a button. here the graphics of the window will disappear and you will be stuck for reading input (input.readObject())
On the other hand , if you call runClient automatically from the class constructor "Client()" the program will work normally.
can anybody give me a hint what's going on?
Why does the program blocks in the first case for input?why not the second?

}The problem is that you can NOT access a method between classes unless the method is static.
THIS IS WRONG!
public class Jack{
private pale;
private void GoUpHill()
{pale = full;}
public class Jill{
public init()
Jack.GoUpHill();
}It is wrong because "private void GoUpHill()" is not declared as static.
THIS IS CORRECT!
public class Jack{
private pale;
private void GoUpHill()
{pale = full;}
public class Jill{
public init()
Jack.GoUpHill();
}Note that "private static void GoUpHill()" is declared as static. That will work, but it will give an error because "pale" is not declared static. Obviously, you're going to need to make all your objects static... or, you could do this:
public class Jack{
private pale;
private void GoUpHill()
{pale = full;}
public class Jill{
public init()
Jack jr = new Jack();
jr.GoUpHill();
}A new instance of the Jack class is made so you can use GoUpHill() at will. You don't need any static methods or objects if you use that method... but it might not always do what you want it do. -
GUI problem with textfields, reading in text from a textpad
Alright well, here is my problem. I am having trouble with aliging the textfields to how I want it but I can't get it to come out how I want it. First, I am trying to figure out how to have the some text appear right above a textfield. Example:
File Name
I can't get it appear that way, the text appears side to side with the textfield. And the other problem is how can I made the size of textfield to how I want it. I was reading that you have to assign a specfic number in the text field.
This is the code I have so far:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class IP_Header extends JApplet
private JTextField lookUp, showInfo;
private JButton analyze;
private JLabel msg;
public void init()
JPanel p1 = new JPanel();
p1.setLayout(new GridLayout(3,2));
p1.add(new JLabel("File Name"));
p1.add(lookUp = new JTextField());
p1.add(analyze = new JButton("Analyze"));
p1.add(showInfo = new JTextField());
msg = new JLabel(" ");
Container cp = getContentPane();
cp.setLayout(new BorderLayout());
cp.add(p1, BorderLayout.NORTH);
With this what I am tryin to do is as follows:
File Name
* "TextField" * *
**************** * This is a textfield where I am just going to
* have some text appear in it
* "Button" * *
Thank you for your help. I hope you can help me. I haven't done java for a quite a while. Thanks againThanks for help ... really helpful and understanding. I am trying to read a file from the computer which has some numbers in it and I want those numbers to be shown on the textfields individually. The numbers are in a notepad file and they are .... 4, 5, 200, 780, 1, 0, 0, 12, 6, 0, 129, 24, 21, 44, 133, 62, 159, 7. I got the program to compile and everything by adding the code that I believe should work . But whenever I put the file name in and press the button analyze ... it gives me a error saying "Exception: access denied (java.io.FilePermission c:\TCP read) .. can't quite get it ...here the code:

Rational Numbers GUI; Problem Displaying Answer
I have to make a GUI that adds, subtracts, divides, and multiplies rational numbers. You input them as fractions. I think most of it is right, it does compile, but I don't know how to get my answer to display. I tried simple stuff like just adding it into the setText part at the end, but is there something that I'm missing like convert it to a string or something, I don't really know, I'm still very new to all this.

I am new to GUIs and have been working on a project for quite some time now. My problem is that I have a program working perfectly fine when I compile and run it on JGrasp (it's a demo version using just jOptionPanes). I am amking the GUIs in Netbeans. But when I run some of the GUI java files that I make in Netbeans on JGrasp, it gives me package errors. Can someone tell me what I need to "package" or import onto jGrasp in order to get it to work. I really don't know much about packages too much either.
Here's an error sample:
Add.java:141: package org.jdesktop.layout does not exist
org.jdesktop.layout.GroupLayout InputPanelLayout = new org.jdesktop.layout.GroupLayout(InputPanel);
This is from JGrasp, I don't get any errors compiling it in Netbeans...it's really odd.>
Add.java:141: package org.jdesktop.layout does not
exist
org.jdesktop.layout.GroupLayout
InputPanelLayout = new
org.jdesktop.layout.GroupLayout(InputPanel);
This is from JGrasp, I don't get any errors compiling
it in Netbeans...it's really odd.Well, the problem is that in your JGrasp the package org.jdesktop.layout was not found.
check your packages.

SQL Developer and Java GUI problems
I am having a problem with all the java apps i use, including Oracle SQL Developer. When i load up SQL developer, the top of the "Connections" text is chopped off as well as all the table names in the list when I make a connection. Also the java buttons are rather large. Almost as if they have a carriage return in the text of the button.
Its seems the gui configuration for java has been corrupted, but i cannot find where to modify those settings. I cant find anything on the internet on this. I have checked my video card settings and modified them to see if that is the issue, but it doesnt fix the problem.
Since other java apps do the same thing, I know its a java issue, but Ive uninstalled all the JRE's and JDKs i have and reinstalled them, and I still have the problem.
Im on an Windows XP box and running the JDK and JRE 1.5.0_09 versions. Any help would be appreciated. its very annoying to not be able to read some of the text in the java apps including sql developer due to the tops being cut off.
I have an ATI RADEON 7000 on an DELL optiplex gx620.
any help would be appreciatedThe first thing to try, if you haven't already, is to update your video driver.

Hi
I have installed solaris 10 x86 in my pc having lg monitor standard monitor 2.54 celeron processor , installation was smooth with no problem , after booting iam not able to get gui it is out of range frenquency error in the monitor ,but iam able to work in cli
will any body to how resolve it
With rgds
TarunThe trick is to edit your xorg.conf file to only
include the frequencies your monitor can support.
Simply comment out the odd ones you know don't seem
right. To be on the safe side I would set it to
800x600 60hz just to get it up and then adjust as
needed.This is exactly my problem also. However, being a newbie to Unix, I am at a loss for where Xorg.conf resides. I also don't seem to have Xsun at the location in the previous message.
Any ideas? Thanks, Tony -
Hi All,
we are using SAP logon 640. In screen painter we are not getting GUI. we are getting the screen in Alphanumeric mode, But not in Graphical mode. How to resolve this problem.
Thanks in Advance.
Regards,
chandra.
Message was edited by: K Chandra Sekhara ReddyHi k chandra,
1. I supppose, the alphanumeric
screen painter comes up.
2. When it comes up,
UTILITIES------>SETTINGS
3. a new window will come
TICK the chekbox for
'Graphical Layout Editor'
4. Then try, it will work.
5. <b>If still it does not work,
then another problem could be
SAP GUI Installation.
6. When installting sap gui,
we have to select the component for
Screen Painter GUI.</b>
(Probabably it was not selected when
installing on your machine)
7. Then it will come.

Hi all,
Well basically I have 3 classes; one is called the loader which has the main function and all it does is call the second class which is the GUI class. This class buils up the GUI. The Third class however is a class which has an infinite loop inside until a button on the GUI is clicked. HOWEVER... due to the infinite loop, the GUI stays inactive until the loop ends which basically is like having a crashed GUI and thus the button can never be clicked!!
What do you suggest? Shall the loader load the third class and the third class loads up the GUI? Or is that not practical?
Thanks allHi again,
I still have a similar problem.
basically whats happening is...
From the GUI I launch a class with an infinite loop !!
Part of the Loop is to await a connection and when connected, a new Class is again launched, it processes and closes itself, and returns back to the infinite loop !!
I would like to know how I can Detach from the infinite loop to keep the GUI working...
thanks all -
Hi I am working with jdev10g (120x19dbg)
I have created one query region.this shows simple as well as advanced search.
in advanced search i have 15 criteria, i have mapped them properly and search is also happening.
My problem is related to UI part. In advanced search all 15 criterai comes in one column (which takes away full page from top to botyom) and also prompts are wrapped.
At the same time simple search GUI works perfectly.
I don't why this is happening...
pls help
NaveenAre you getting alignment issue with 4 columns also? Did you try to resize the window and test? Also test with 2-3 different browsers.
