Hi. I have a Swing GUI that I developed Netbeans Matisse in Linux. For some odd reason, the look and feel of the application looks different when it's run by root (it looks better, actually). Is there a reasoning for this? Thanks ...

Using GroupLayout and the code below, I noticed that the leftPanel is not updating it's preferred size. I thought this was supposed to be automatic and appears to work in other layout managers. How can I get that behaviour with GroupLayout? import javax.swing.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; ...
Today, I've been dabbling in using jython to create a GUI using swing. I'm no expert programmer, so I decided to have a go at using the Netbeans IDE to design the interface and then adapt the output for use in jython as I have more experience in python than Java. After working through the code I managed to rid all the syntax errors but a...
What I want to know is, how can I create GUI elements using swing inside a Jython class so that they can be referenced from outside the class, and I can use statements like button.setText("Hello") on an object that was created inside another class. For example: foo.py: from javax.swing import * class Test(): def __init__(self): ...

Hi, I have a GUI application in swing, implemented in NetBeans. For the various functionality provided from the input of the user, a jar is used, which uses log4j for logging. All is ok, but I have to redirect information from log4j to a text area in my GUI. I have found that to redirect from log4j to swing text area, one must extend an...
Executive summary: What kinds of sound architecture choices are there for displaying thread-safe, dynamic data in real time using Swing? Details: I have recently completed writing a multi-threaded, automated trading platform in Java. I say "platform" because I have made it very easy to implement new and multiple trading programs by su...

I am currently trying to program in Scala but I guess this can generally applies to other programming as well? In Swing, we generally organize our code and logic in a single class (perhaps our Frame or Panel). What I have learnt in the pass has always been dealing with a class as well. I am wondering if there is any medium size (not too...

The purpose of the DropDownPanel is to be able to hide and show another Component on it. If you click on the title of the DropDownPanel, the hosted Component (now it is a JTable) is set to visible or inv...

The GridLayout automatically did this. But I want to add another row and column to the grid which size is not the same as the other ones. That row/column...
