interactivemarker processfeedback callback as a class method

edit

Hello

I wanted to make a class that contains an interactivemarker server

Something like this http://wiki.ros.org/rviz/Tutorials/Interactive%20Markers%3A%20Basic%20Controls

Problem is, I want to do this in a class. Thus I need to set the processFeedback callback as a class method.

I cannot compile the instruction

interactive_markers::InteractiveMarkerServer server->setCallback(int_marker.name, &ClassName::processFeedback);

or

interactive_markers::InteractiveMarkerServer server->setCallback(int_marker.name, &ClassName::processFeedback, this);

A similar issue for ros subscribers and service servers has been solved here http://wiki.ros.org/rviz/Tutorials/Interactive%20Markers%3A%20Basic%20Controls

Does anybody know of something similar for interactivemarker servers?

Thanks

Miguel
