Hello all,
I want to create a panel in RViz (part of a plugin) and this panel would contain widgets allowing me to create/modify ROS parameters.
Now, as is, my RViz panel will not be updated if the parameter gets modified outside of RViz - the parameter value displayed by RViz will be wrong. Hence my question: is there a ROS mechanism allowing to get notified on parameters value change? ...or another mechanism allowing to sync my panel?
Should I simply setup a 5Hz timer to update my panel? Or is there a better approach?
Thanks,
Antoine.
