Simply put, I'm looking for a way to make an ImageIcon from an SVG file using the batik library. I don't want to have to raster the SVG to disk first, I just want to be able to pull an svg out of the jar file and have it land as a UI element. I feel like this should be reasonably easy, but the batik javadocs aren't telling me what I ne...

Long story short, I'm making a custom Swing component that's basically a JTable with a panel on its side. The table should of course be scrollable and have a table header, but since I only want the header to be above the actual JTable and not above the side panel, I had to pull some tricks to make it work. But that part works fine. H...
What is considered best practice deciding how to define the set of JAR's for a project (for example a Swing GUI)? There are many possible groupings: JAR per layer (presentation, business, data) JAR per (significant?) GUI panel. For significant system, this results in a large number of JAR's, but the JAR's are (should be) more re-usable -...

So, I'm working with swing and I need to find a clean (non-CPU-hogging-way) to introduce a delay on a text field. Basically, users will enter a number into this field and the keyReleased() event checks that the input fits a few parameters and then assigns the value to a data storage element in the program. If the data is invalid, it di...
