Hi, I wanna create a JTable with a row header. This question seems simple and I could find a lot of tips on google search.

Simple enough question: I have a string containing HTML that is being handed off to a JEditorPane for user consumption. Can I attach a CSS file (or string containing CSS rules) to allow for more specific styling of the text? ...
Hi -- I have an unusual situation where I need to have a JTree with each node containing 2 checkboxes and a label (with the ability to add a listener to tell when any of the potential checkboxes are checked). I also need the root node to have the same layout (which I'm assuming means creating a JPanel with 2 JCheckBoxes and a JLabel), wi...
The program I am writing has a Swing GUI and several of the components have Tooltips. These are all on JButton, JCheckBox and JRadioButton components, they are set using the setToolTipText method and all work perfectly. I have just tried to add one to a custom component that extends JPanel using the same method and no tool tip appears. T...

I'm currently searching for a 3d library that I could embed in a Swing application. This library doesn't necessarily have to be a huge thing as I mainly intend to give a 3D representation of some shapes, and certainly rotate around them. My main concern is to get something as easy to set up and to deploy as possible. Do you have any c...

I'm a little confused about the Swing painting model. Suppose that I have a JComponent comp, and I do something like: c.setBackground(Color.RED); c.setBackground(Color.YELLOW); Obviously, the end result is that the color is yellow.

I'm somewhat new to Swing programming, and I find that as much as I love the power of GridBagLayout, if you've got a lot of components, there are lots of lines of code just setting up the constraints for the layout. What are some good ways to keep this under control, besides using a visual editor? ...

Hi all, when I try putting my JLayeredPane inside a JScrollPane I get a blank window (with white background) instead of the content I am trying to render (it could be an image, a button, a canvas). Does anyone know of a problem with layout managers that might cause it? Is it possible? EDIT: thanks to camickr help, I can now put a JLaye...
(Edited for clarity) I want to detect when a user presses and releases a key in Java Swing, ignoring the keyboard auto repeat feature. I also would like a pure Java approach the works on Linux, Mac OS and Windows. Requirements: When the user presses some key I want to know what key is that; When the user releases some key, I want to ...
Hi, with some fuzz around Windows 7, does somebody have experiences with Java compatibility with Windows 7? Should this be a concern or do the programs probably work ok? I'd be especially interested if somebody has experiences with Swing applications? The versions available seem to be beta versions so they won't provide perfect basis ...
I read some equinox code and doc. I came to understand that, at present, only class loading for java.* packages are delegated to the parent classloader(given that i have not modified org.osgi.bootdelegation property, which by the way seems to be null). Then who is loading the javax.swing.* classes. I have not mentioned it anywhere in the...
