Not sure exactly what your FeatureInfo handler does, but it feels like it might be more of a control than a handler. Perhaps it could be a control that used the Feature handler (which can be configured to respond to a click)? Or maybe it does something like GetFeatureInfo (from WMS)? In this case, it should almost certainly be a control (because it doesn't represent a complex sequence of browser events). > What is the best way to deactivate these other handlers? Handlers are designed to abstract out sequences of browser events. They are typically sent to controls to modify the behavior of a control. When you activate a control, the appropriate handlers are activated. Deactivate, and the handlers are deactivated. We want there to be many controls in a given mapping app. Perhaps many will be active at one time. In this case, any handlers associated with these controls need to play well together. The order of activation is important. Controls (and their handlers) that are activated later get priority in event handling. > Is there a way to make a Handler exclusive, or to remove all other handlers > from the map? It wouldn't make sense necessarily to silence (or plug the ears of maybe) all handlers on the map. This would be akin to unregistering all event listeners just because you want to register a new one. You're better off having your application control the order of control (and hence handler) activation. This is a somewhat tedious task. Because of this, we have a control panel class. If you add a tool type control to a control panel, when it is activated (and it's handler is activated), it will deactivate all other tool type controls (and their handlers) on the same panel. I think this structure gives enough to work with in most situations. Perhaps I've totally missed what you're trying to do though. If you give more detail, I can try again.
