问题 I'm trying to create some authorization logic for my custom components. What I want to achieve is that I can set an attribute which disables the component entirely, e.g. when a user has read-only rights. I tried with a button but am not really satisfied with it.

问题 I have a question about implementing a Swing control which uses a custom class as one of its properties. My goal is to use this control within the netbeans IDE and configure it in design-time like any other component.
