Recently in thinking about an application I'd like to write, I realized
that it would be good to have the following kind of JComponent:
There's a sub-class of JPanel which contains a JTextField and a
JButton. The component has a list of validators for the text field.

I'm using a numeric JSpinner to select stuff to display by other components
in my GUI.  The user may make modifications to the other components which
the program validates.  One scenario that triggers validation is for the
user to select a different number with the spinner.  If ...

Anyone know where the synth XML file is supposed to be located. My app
never seems to pick it up no matter where I put it. I run a *.bat file

xml file is not in the jar, but also in the bin dir. I put the xml file

            I am currently trying to print a multipage JTable but the
the thing is on the left hand side of the JTable does not have any grid
lines and i have tried to draw a rectangle around the jTable before
printing it but nothing is happening.

Thanks in advance, Filip

Running in a browser, I get angled lines only under Win2000, not XP.
I use the (semi-secret) command:
tree.putClientProperty( "JTree.lineStyle", "Angled" );
but it doesn't seem to matter under XP.

I sometimes get the following exception when I first bring up my GUI.

triggers it. Since the problem happens intermittently and is not
reproducible, I am really at a loss. Any help in debugging this will be

I have a question about printing components in Java, and in particular
printing a JTextArea component. In the example below I am simply trying
to print a single JTextArea component. As you will notice I am sizing

Hi, on Java 1.4 versions code toolBar.setRollover(true) worked well.
It hides JButtons borders, and makes them(borders) visible when mouse was
over them.
But on Java 1.5(currently 1.5.01) this code toolBar.setRollover(true) does

I have been through other posts regarding this problem.  But their
solutions don't fix my problem.
I have tried different variations, but the basic is :
    ImageIcon lIcon = new ImageIcon("pic.bmp");

How can I change the color of the node icons in a JTree?
I looked at DefaultTreeCellRenderer, but it only has methods for
changing the foreground and background colors of the text or outlining
the text.  I couldn't find any methods that allow you to change the
