Well, it should get added into the menu automatically. There is a method "getStaticLabel()" which needs to deliver the String that will be used in the menu. How it happens is by magic :-)
The current documentation that is there for developers is very out-of-date. I tried a long time ago to write up some instructions, but they were a dismal failure, and I haven't bothered with it too much since. I know, bad bad bad. Here are the basics: The key is what the class type is. A class called "org.apache.jmeter.gui.util.MenuFactory" uses a class called "org.apache.jorphan.reflect.ClassFinder" to find all available classes of certain types. For instance, it finds all visualizers, all samplers, all timers, all config elements, etc. These are grouped in their categories. When you implement one of these, the class must indicate which group it belongs in. However, this is mostly for flexibility - usually the group is obvious, and you do not need to do anything except extend AbstractVisualizer, which takes care of this. You'll see methods in there like "createPopupMenu()" and "getMenuCategories()". These methods call on the MenuFactory to do what is necessary to make your visualizer play nice with the menuing system. Furthermore, visualizers are especially easy because you likely don't need to override the "createTestElement()" method. The AbstractVisualizer creates a org.apache.jmeter.reporters.ResultCollector, which is the runtime stand-in for the GUI component that collects the sample logs and delivers the info to your visualizer via the "add()" method. Now, that may not have made much sense, because I don't know if you understand the big picture of how JMeter separates GUI code from the engine code, but that is a discussion for another time. -Mike On 8 Dec 2002 at 10:44, James Whitfield wrote: > Thanks so much for your support Mike, sorry my response wasn't as rapid as > yours.
