2013-09-23 08:23:09 -0500 | answered a question | Subscribe to a topic in rqt plugin Ok, I found the problem. It is important to get the NodeHandle from the plugin and not to create one yourself. |
2013-09-23 03:09:55 -0500 | commented answer | Subscribe to a topic in rqt plugin Yes, it seems that my node appears when I do not "hide Debug" and it also subscribed to the topic. I do not initialize my node handle at all, so its going to be standard constructed. It seems like the problem is in the callback, which does not get called |

After I boiled down the code it looks essentially like this: Of course sub and n are declared in the header and the code compiles. Only problem is: Nothing happens.. |
