2019-09-20 02:37:34 -0500 marked best answer Debugging a rqt plugin in PyCharm

Hey guys,

I am developing a rqt plugin in Python at the moment and I am using the recommended IDE PyCharm.

When I get errors I always try to debug with print messages.

I am wondering is there a good debugging solution to debug a rqt plugin in PyCharm?

Thank you very much in advance!

Best regards

2018-04-08 11:26:05 -0500 marked best answer Writing a panel for RViz in Python / accessing RosTopicHz from C++

Hey guys,

I would like to write a RViz panel where I can see the actual publishing rate on a given topic (same thing I can do with "rostopic hz" from command line).

I have seen in the tutorial that panels for RViz are written in C++ and the class ROSTopicHz is written in Python.

Is there any way to access the class to get the actual publishing rate based on a given topic name from C++?

I could implement the functionality from ROSTopicHz in C++ but the problem I am facing is that I won't know prior which topics and message types I will subscribe to (this should be selectable during runtime). So I would need a way to dynamically create subscriber objects and callback functions in C++.

Does anyone have an idea how to do this or a way to write a panel for RViz in Python directly?

Thanks in advance!
