InteractiveMarker hook into mouseover/hover?
Is it possible to execute a callback for an interactive marker on mouseover? I can capture and click event and use it just fine, but I'd like to be able to capture a mouseover (or hover) event as well. The markers already highlight on mouseover, so I'm hoping it isn't difficult. Does anyone know how to do this? I'm on Ubuntu 12.04 with ROS Groovy.
