WindowsLookAndFeel problem
I'm running into a problem when I set the WindowsLookAndFeel as the default "skin".
Basically, I get dots under text for menus, tooltext, etc. This isn't something crucial obviously, it just looks dumb. To get an idea what I mean, visit:
http://www.tecnogize.com/guiprob.gif
(image of a tooltip with the problem)
See the dots under the o's and t for example in the yellow tooltip? That's what I'm talking about, and this is in the menus and other components as well.
Any of you ever ran into this? Know a way to fix it?
Thanks, Jens
I thought UIDefaults was used to store those kind of properties. Access to the UIDefaults is provided by the UIManager class. Use UIDefaults.put( Object, Object ) to set the font.
question: how do I know which property is the one I seek?
answer: Well, dump your UIDefaults instance into a file, search that file to see if it contains a key like "TextArea.font", if yes, use it to setup your font. If not, well, shit happens :) Note that you only have to dump the file once. After just recompile your code with the found property name defined a a constant or even hard coded.
I know this is a very empiric solution, but the property names do not seemed to be documented. They might even differs from one LookAndFeel to one another.

WindowsLookAndFeel on Linux : BIG and complete PROBLEM
Hello,
I have implemented a GUI application with the windows look and feel. I work under Linux with the jdk 1.3 and eclipse.
To run my application with the windows lf, I add the following lines in my code :
System.setProperty("os.name","Not Windows");
try {
UIManager.setLookAndFeel(new WindowsLookAndFeel());
} catch (Exception e) {
e.printStackTrace();
SwingUtilities.updateComponentTreeUI(getRootPane());
In Eclipse, it works well, but an execution from the line command in a Xterm generate the following exception :
java.lang.NumberFormatException: multiple points
at java.lang.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:1073)
at java.lang.Float.valueOf(Float.java:186)
at com.sun.java.swing.plaf.windows.WindowsLookAndFeel.initialize(WindowsLookAndFeel.java:108)
It seems that the problem is caused by the following line :
System.getProperty("os.name","Not Window");
the system property os.name is parsed as a float.
what can I do to run my application with the windows lf and under linux ?
any help will be helpful

ialize(WindowsLookAndFeel.java:108)Make sure that Eclipse is using the JDK matching the JRE you use to run the program (Windows/Preferences/Java/installed JREs or somesuch)
It seems that the problem is caused by the following
line :
System.getProperty("os.name","Not Window");
the system property os.name is parsed as a float.Using an official System property is shooting yourself in the foot. You can't tell what else on in the Java runtime has a depency on it. You can set your own property
for this (System.setProperty("MyFalseOpsSys","Not Windows")). I wonder what use you have for it since you force the Windows L&F anyway?

any help will be helpful Maybe find a JRE which supports it natively. Or, if you are very lucky, extract the relevant classes and resources from the JAR of a Windows JRE (in Sun's rt.jar, com/sun/java/swing/plaf/windows/) and put them into some independent JAR you add to your Linux classpath. For better luck, use the very same version for both JRE. Pray that there are no native methods involved. -
WindowsLookAndFeel on Linux : BIG PROBLEM
Hello,
I have implemented a GUI application with the windows look and feel. I work under Linux with the jdk 1.3 and eclipse.
To run my application with the windows lf, I add the following lines in my code :
System.setProperty("os.name","Not Windows");
try {
UIManager.setLookAndFeel(new WindowsLookAndFeel());
} catch (Exception e) {
e.printStackTrace();
SwingUtilities.updateComponentTreeUI(getRootPane());Availability of specific L&F is platform dependent. On a given Platform, you usually have the choice between the local one or the standard Java one (aka "Metal").
Forcing innocent Linux users to use a Windows L&F would not do much good to the popularity of your software anyway :-) "Look" isn't everything, the "Feel" part is important too (default keys, some window behavior), and your app you remain consistent with the rest of the Linux desktop. -

}Now the problem I'm having is changing that class to a JFrame, it seems simple but I keep having problems like when it runs from another JFrame nothing pops up. I can do it like this:
FinalTest ft = new FinalTest();
ft.setVisible(false);
JPanel example = ft.contentPanehowever I will probably be marked down on this for bad code. I'm not asking for the work to be done for me, but I'm really stuck on this and just need some pointers so I can carry on with the project. Thanks,

I'd actually consider your GUI being a JPanel instead of a JFrame quite good design - makes it easy to put the stuff into an applet when necessary...
Anyway, you should set setVisible() to true to make it appear, not to false. Otherwise, I don't seem to understand your problem.That is actually my problem. I am trying to convert this JFrame to a JPanel -
Problem with writing and reading using serialization
I am having a problem with writing and reading an object that has another object in it. The purpose of the class is to write a order that has multiple items in it. And there will be several orders. This is for an IB project, where one of the requirements is to utilize a hierarchical composite data structure. That is, it is "one that contains more than one element and at least one of the elements is a composite data structure. Examples are, an array or linked list of records, a record that has one field that is another record, or an array". The code is shown below:

Problem with setMnemonic after upgrading to 1.4.2
Hi,
setMnemonic doesnt seem to work properly for JButtons after upgrading from 1.3.1 to 1.4.1. Hot Key works but underlining doesnt show.
In our app, we have our own controls which are basically derived from Swing controls. In this case JButton.
I have tried using both setMnemonic API (char as well as int) but no luck. Look and feel we use is Windows look and feel (W2K). Font is Dialog. One thing I have noticed is that if I donot set the look and feel in my app. It seems to work fine. (Metalic).
Anybody has any clue on how to fix this issue ?
Thanks in advance
SohanHi,
Here is a code sample for the above problem.

public class TestFrame {

When I use b extends Entorno1 and I insert as JPanel of JTabbedPane, not show it.
this.Tabbed1.addTab("Primera Pesta�a", b);
But this yes show it:
this.Tabbed1.addTab("Primera Pesta�a", a);
Why ? ..
Thanks !Your constructor is actually a method and not a constructor.
Therefore calling new Entorno1() returns you a blank panel.
change this
public void Entorno1(){
...to this.
public Entorno1(){that should do it..

JMenu dismissal action in WindowsLookAndFeel changed for 1.4.1_02 ?
Hi all,
It seems to me that the way menus are 'dismissed' in WindowsLookAndFeel has changed in the 1.4.1_02 release. The example program included in this post, when run on 1.3.1_06 (in WindowsLookAndFeel mode) keeps the menu visible until the selected action completes (same as for metal/default L & F modes). However, when run on a 1.4.1_02 system, while the default and metal L & F actions are unchanged, when using WindowsLookAndFeel the menu disappears immediately after the menu item is selected, and leaves an 'empty' rectangle behind! Seems to me that this action change is a bug, but I am hoping that someone might be able to explain what is going on. I could perhaps live with this if the background under the dismissed menu was repainted as part of the dismissal action - but I am unable to make this happen! Again, any insight from others would be most welcome! I am sure this worked with 1.4.1_01, but cannot test this at present.

Thanks in advance.First, I don't see where you are tying to set the combo box on the first two columns. I only see it for the 3 and 4.
Also why are you putting combo boxes in columns that are not editable:

//Note that the data/cell address is constant,
//no matter where the cell appears onscreen.

Akulahi sir ,
thaks for u'r suggession.Its working fine but the
properties of the previous tree were not working
after setModel() property .like action at leaf node
is not working,I'm sorry but I don't understand. I think you are saying that the problem is solved but I can read it to mean that you still have a problem.
If you still have a problem then please post some code (using the [code] tags of course). -

Hi,
i have created a specific JTextField that, among other things, only can take in numbers. To do this I have modified the Document of the textfield.
My problem is that the user can toggle between two different textfields using a combo box. One textfield of this kind and one standard JTextField. When the user toggles the focus should be on the text field, and if there is text in the textfield it should be highlighted. This works fine for the standard JTextField using requestFocus() on the textfield, and a FocusListener that does a selectAll() when the text field recieves focus. But my "enhanced" textfield gets a null pointer exception when the selectAll() occurs. Any ideas?
The TextFields new Document
protected Document createDefaultModel() {
return new FaTkTaxNrDocument();
protected class FaTkTaxNrDocument extends PlainDocument
public void insertString(int offs, String str, AttributeSet a)

char[] source = str.toCharArray();

// Ska endast f� plats 7 tecken
if(this.getLength() > 7) {

for (int i = 0; i < result.length; i++) {
if (Character.isDigit(source)) {
result[j++] = source[i];
if (offs+i == 6) {

Keyboard problems with joptionpane.ShowConfirm
hello,
I am using show confirm dialog and there is a yes and no button with it.
I want the software to exit when the user clicks yes button.
the code works fine when the user uses mouse. but when I use the enter key on yes or no button, the application exits in both the cases.
further more if I perform the same action with the space bar on the keyboard it still works fine and when I hit space bar on the no button the application stays. but with enter key the application doesn't seam to take the right yes/ no value in the integer.
what's the problem
and how do I correct it.
thanks
