In NetBeans IDE 6.1 how can I get icons for my custom GUI components in the GUI editor? <p>While this is by no means really important, I was just wondering if the community knows how to put icons for my custom GUI components that show up in the NetBeans GUI designer.</p> <p>What I did was make several Swing components. Then I use the menu options to add them to the GUI palette, but they show up with "?" icons. It would be nice if they showed up with icons similar to swing components such as <code>JButton</code>, especially for components which are subclassed from Swing components.</p>
