Visual Class Jframe

Hi !
My problem is about visual class. How can I open JFrame in same window? When I click on a radio button on the JFrame, I want to open an another frame that I created. But I want that first frame must closed. Than another opens.
For example,
WaiterMenu childWindow = new WaiterMenu();
childWindow.setVisible(true);with this part of code I can pass to other frame but first one doesn't close. What can I use for this?
Thanks.

One more question.
I wrote it but I got this warning. How can I correct this problem? Where do I have to write this MainMenu.setVisible(false)
Warning :
Cannot make a static reference to the non-static method setVisible(boolean) from the type Window
Part of my code :
private JRadioButton getJRadioButton() {
          if (jRadioButton == null) {
               jRadioButton = new JRadioButton();
               jRadioButton.setBounds(new Rectangle(18, 69, 21, 21));
               jRadioButton.addActionListener(new java.awt.event.ActionListener() {
                    public void actionPerformed(java.awt.event.ActionEvent e) {
                         WaiterMenu childWindow = new WaiterMenu();
                         childWindow.setVisible(true);
          return jRadioButton;
     }

Eclipse Visual Editor - no "Visual Class"

I have installed the recent eclipse and eclipse-ve packages. Eclipse says that the Visual Editor is installed. It says the "Visual Editor" is of version 1.4.0 and that the "Visual Editor Property Sheet" is of version 1.5.0.
As far as I understand, I should now be able to create a new "Visual Class" but this menu option is not appearing. Is there something I'm missing?

Same issue here.

Turning off syn visual window (syn visual class)

When I start a particular function in a program, I get an error message asking me to turn off the program "syn visual window (syn visual class). I have T510 Thinkpad. Does anyone know how to turn this off? From a Google search, I understand it has something to do the with UltraNav and that the problem is specific to Lenovo Thinkpads.

back in the day (OS 7/8/9) you had what was called t he extension manager. when i would work in cubase i had an extension set that was stripped down - similar to what you are asking.
now things are different. OS X is very efficient.
the only thing you need to do is only run the apps you need to have open (don't have mail, internet, etc. running while recording)
there are 3rd party apps that will remove window shadows, etc. - but I don't think it is necessary.
Max out your ram, and only run the apps you need running and you should be fine.

Using same databaseClass from each of class (JFrame)

Hello,
I build a class named databaseClass, It having void/function getConnection, closeConnecion, getStatement, closeStatement...... That doing all the jobs about database connection and working fine.
My question is how to let all the classes(JFrame) are accessing ONE databaseClass with optimize preformance.
    private databaseClass dbClass;
    private Connection conn;
    dbClass = new databaseClass();
    conn = dbClass.getConnection();I wonder will the class (databaseClass) be called several time if several classes (JFrame) is opened on the same time? (each of JFrame created one of databaseClass object)
I only know to create databaseClass object on main project class and pass it through to all of JFrame, But I feel a bit stupid.
Is there an alternative way to calling SAME ONE databaseClass from every JFrame classes
Possible? and How? Thanks!!!

Eventually, I tried tidy change of my databaseClass Object
1) add private static int numConnection=0; as counting number of connection existing
2) add getInstance() return static databaseClass Object
    public static databaseClass getInstance(){
        ++numConnection;
        return new databaseClass();
    }3) add public void finalize() to do whatever when I removing databaseClass Object
    public void finalize(){
        --numConnection;
    }full source at [http://experts.kennam.com/databaseClass.java|http://experts.kennam.com/databaseClass.java]
Above are what I known to do to my goal, Any suggestion?!

Visual Editor cannot show the class extending a visual class of JFrame

Hi,
We want to create a base frame (BaseFrame) so that every form in our application extending it to share some common properties.
But i found that the class (OrderFrame extends BaseFrame) cannot be shown properly in Visual Editor (run is ok).
Is there any way to resolve it?
Code Ref:
BaseFrame.java
public class BaseFrame extends JFrame {
public BaseFrame() {
try {
jbInit();
} catch (Exception e) {
e.printStackTrace();
private void jbInit() throws Exception {
this.getContentPane().setLayout( null );
this.setSize( new Dimension(400, 300) );
this.setTitle( "Standard JFrame" );
OrderFrame.java
public class OrderFrame extends BaseFrame {
public OrderFrame() {
try {
jbInit();
} catch (Exception e) {
e.printStackTrace();
private void jbInit() throws Exception {
}

Olaf,
When using your own beans it is best to create the bean in one project, and then use it in a second project. So in your example; use Project1.jpr to create, compile, test, debug BaseFrame.java. Then, once you are satisfied with it, use Project2.jpr to create, compile, test, debug MyInternalFrame.java. Your scenario works fine when adopting this approach. However, be sure that MyInternalFrame.java includes the necessary import statement for BaseFrame, and be sure that the classpath for Project2.jpr includes the path to BaseFrame.class. If you are using the default classpath settings for each project (i.e. myclasses) then the classpath concern will be taken care of for you already.
Enjoy.

Hi,
the situation :
BaseFrame extends JInternalFrame
and
MyInternalFrame extends BaseFrame
Now I want to edit MyInternalFrame in the visual editor.
I tried that by making a bean of BaseFrame and addiing the bean to the Palette but MyInternalFrame won't show up in the editor,
anybody knows how to set this up ?

Visual Class: Set a label in main window from dialog box

Hi,
Firstly my project is a visual project and at the time being has only 2 classes, both visual. One a main window and then one a dialog.
The project is about a gym membership, and what i want it to do at the moment is to set the name text box i have in the main window by typying it in another text box in my dialog. Understand?
This is my text field method in MainWindow...
public JTextField getNameTextField() {
          if (NameTextField == null) {
               NameTextField = new JTextField();
               NameTextField.setBounds(new Rectangle(164, 28, 193, 26));
          return NameTextField;
     }And my New Member text field in the dialog, called NameDialog
private JTextField getNewMemberTextField() {
          if (NewMemberTextField == null) {
               NewMemberTextField = new JTextField();
               NewMemberTextField.setBounds(new Rectangle(36, 56, 209, 28));
          return NewMemberTextField;
     }In the dialog i have created a button called,"OK" and if i press it without entering a String then an error box appears which all works correctly. Then as you can see if i enter a String here i want this String to be entered and showed in my MainWindow class in the name text box.
But this is not working and i am having trouble here after the else...
else {
GymMembershipMainWindow mainWindow = new GymMembershipMainWindow();                                 mainWindow.getNameTextField().setText(getNewMemberTextField().getText());
NameDialog.this.setVisible(false);Sorry but do you understand what i am trying to do? Apologies if any of it is unclear.
Would appreciate any help. Thank you.

Ok well there is quite a bit, but only 2 classes. This is the first class which is the main class.

The problem i am having is in the OK method in the dialog class. At the 'else' i want the text that is inputted into the text field in the name dialog here, to appear into the text field in the main window for the name.
Understand me? Sorry. Thanks

Problem visualizing a JFrame while doing other things

I'm triing to visualize a "Waiting" Window with static labels on it saying "Wait please, this process can take some time..." while doing something like 20000 insert in a database, but the window shows only at the end of the process (when i have to open another window, so it displays for only a millisecond). How can i solve the problem? Code is like this:
public class myclass extends JFrame {
// some dichiaration
public myclass() {
try{
jbinit()
} catch ...
// do alot of calculation
private void jbinit() {
// all the stuff like setsize and labels definition
}

You're probably doing the entire work in the Swing thread and block it from doing anything else.

Impossible to find JFrame class

I'm on Linux Mandrake 8.2 and when I compile a file which contains:
import javax.swing.*;
class Test extends JFrame
I obtain the following message:
Cannot find class JFrame
However I have included in my CLASSPATH the path:
/usr/j2sdk1.4.0/jre/lib/dt.jar
And have exported the CLASSPATH but without any result, I obtain always the same message:
Cannot find class JFrame
What I can do?
Thanks,
-- Gandalf

I don't know about Linux, but on Windows JFrame is in
\j2sdk1.4.0-rc\jre\lib\rt.jar. dt.jar is the design-time jar for bean info classes and related .gif images.
Try adding that to your CLASSPATH instead.

Eclipse visual editor does not work.

If I try to create a new visual class two error messages pop up:
"IWAV0138E Remote VM terminated too soon. See .log file for trace of output."
"An internal error occurred during: "Create Remote VM for Visual Editor for Java".
IWAV0171E Could not create a socket connection to remote vm. This is often due to your firewall blocking access from your java to do local access."
Here is the full error log: http://pastebin.com/m4c700db3
I have no firewall enabled:
core@c-laptop:~$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
I've read that it could possibly happen due to incorrect /etc/hosts file. Here is mine:
core@c-laptop:~$ cat /etc/hosts
# /etc/hosts: static lookup table for host names
127.0.0.1 c-laptop localhost
#<ip-address> <hostname.domain.org> <hostname>
192.168.1.102 n810 n810
192.168.1.101 serv serv
# End of file
Any ideas?

I'm guessing 'c-laptop' is the name of your machine? My line looks different in /etc/hosts, I just added my name to the end and left the original domain:
rob ~ $ cat /etc/hosts
# /etc/hosts: static lookup table for host names
#<ip-address> <hostname.domain.org> <hostname>
127.0.0.1 localhost.localdomain localhost rob-thinkpad
# End of file

Using visual editor with a modified component...

Hi,
I'm creating an MDI application with eclipse.
I'm using Visual editor plugin;
Now I've two visual class like this:
public class CommonFrame extends JInternalFrame {
public CommonFrame(){
super();
public class specificFrame extends CommonFrame {
public specificFrame(){
super();
}Now when I open specificFrame class in eclipse, Visual editor try to load GUI interface, but it fails to do this and show me this error:
java.lang.NoSuchMethodException(gui.CommonFrame.<init>())
I grant the code works fine;
the only problem is I must modify GUI class manually or
I must change the code "extend CommonFrame" into "extend JInternalFrame", then graphically modify the class, and then re-change the code.
Is there a way to resolve the above error?
Thank you in advance.
MargNat

My class has a no-args constructor, that is:
public specificFrame(/* no args */)
According to this error message:
java.lang.NoSuchMethodException(gui.CommonFrame.<init>())gui.CommonFrame doesn't.

Missing classes from the javax.swing package?

Can anyone throw any light on what appears to be a missing class from the javax.swing package?
When CelsiusConverter.java from The Swing Tutorial (code fragment shown below) is compiled the JFrame class can't be found.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class CelsiusConverter implements ActionListener {
JFrame converterFrame;Despite the package javax.swing being imported, the compiler does not seem to be be able to find the JFrame class.
CelsiusConverter.java:14: Class JFrame not found in type declaration.
JFrame converterFrame;To attempt to solve this issue all the files in jdk1.5.0_02\lib were added to CLASSPATH.
CLASSPATH was set to C:\Program Files\Java\jdk1.5.0_02\lib\dt.jar;C:\Program Files\Java\jdk1.5.0_02\lib\htmlconverter.jar;C:\Program Files\Java\jdk1.5.0_02\lib\jconsole.jar;C:\Program Files\Java\jdk1.5.0_02\lib\tools.jar;C:\Program Files\Java\jdk1.5.0_02\lib;C:\Program Files\Java\jdk1.5.0_02\lib\ir.idl;C:\Program Files\Java\jdk1.5.0_02\lib\jawt.lib;C:\Program Files\Java\jdk1.5.0_02\lib\jvm.lib;C:\Program Files\Java\jdk1.5.0_02\lib\orb.idl;C:\Program Files\Java\jdk1.5.0_02\demo\jfc\SwingApplet\SwingApplet.jar;.;c:\CoreJavaBook

This is extremely strange... If you're sure it's not a problem in your code or with your classpath, the only other thing I can think to suggest is re-downloading / installing java

How to set focus on opened new JFrame??

Hi,
I have a problem:
I have my active JFrame that I am currently running.
When I press a JButton I have an action that it opens another JFrame,
which is minimized (maybe it doesn't have a focus enabled or something)
How to make the opening JFrame window maximized and make it be the one on the foreground (put the first JRame in background)
Thanks

Try this:
import java.awt.event.*;
import javax.swing.*;
import java.awt.*;
public class JFrames extends JFrame{
     public JFrames(){
          super();
          // exit on close
          this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          // button to create new JFrame
          JButton button = new JButton("New Frame");
          button.addActionListener(new ActionListener(){
               public void actionPerformed(ActionEvent e){
                    // create new instance and maximize it
                    JFrames frame = new JFrames();
                    frame.setExtendedState(frame2.getExtendedState()|frame2.MAXIMIZED_BOTH);
          // panel to add the button to
          JPanel panel = new JPanel();
          panel.setPreferredSize(new Dimension(300, 200));
          panel.add(button);
          this.getContentPane().add(panel);
// display the frame
this.pack();
this.setVisible(true);
     public static void main(String args[]){
          JFrames frames = new JFrames();
}

Eclipse - Visual Editor

I use the eclipse 3.0 and I have installed the visual editor through Help -> Software Updates -> Find and Install...
So I believe it�s installed correct, but I�d like to know what should I do to start it. I tried to change the perspective, there ins�t the visual editor option though.
Does anybody know how to do that?
Thx

VE is not started as a different perspective but rather, as of Eclipse 3.0.2 I have installed, it will open a new perspective as you add a new "visual class" to your project.
A problem I experienced during the initial installation is that Eclipse seems not to be able to build its configuration files all at once.
The online documentation suggests, if you cannot see "Visual Editor" amongst all of the other installed plugin, to delete the following:
/configuration/org.eclipse.osgi/manifests
/configuration/org.eclipse.osgi/.bundledata
/configuration/org.eclipse.osgi/.state
and restart the program. This will force Eclipse to rebuild its configuration files.
(Just to be more careful you could move them instead!).
Hope this will help.
Bye

Conversion from Visual Age for Java 4.0 to JDeveloper

How can I export our visual classes correctly? It's work, but I can't open them for visual designe.

If you'll create a new swing application with a frame in JDeveloper you'll see that JDeveloper uses a JBinit method.
The code you bring over from Visual Age needs to have a JBinit method also to be able to use the visual editor.
The code editor should work just fine with your code anyway.
