I have implemented a Java Swing component that implements Printable. If I add the component to a JFrame, and do this.pack(); on the JFrame, it prints perfect. But if I don't add the component to a JFrame, just a blank page is printed. This code gives a great printout: final PrintablePanel p = new PrintablePanel(pageFormat); new JFrame(...
I'm using a self-made DesktopPaneUI for a JDesktopPane, I've written the proper methods for the class, and I'm running into trouble. When I resize the JDesktopPane, the background image doesn't resize with the frame. The image appears to be clipped at the size it was when the window initially opened. I'm giving it an image larger than th...

My plan is to inco...

I'd like to add persistence to my Swing-based application; and this is the first time that I'm doing something like that. I know how to use Java serialization APIs (though I'm using xstream instead), I know that JComponent's are serializable, but I'm interested in more architectural considerations: how an application should be designed ...
