For sure it's a simply and stupid question, but I cannot find solution.
My Qt5 C++ API works great... except it cannot delete remote parameters/variables
I tried some ways, but I'm unable to do so:
There is no "trap" messages from ROS when use the ! prepending attribute name, but ROS doesn't do anything either xD
It was no important to me until now, as I allways fill all attributes but "comment", clearing it by replacing text with a single space: " ". But cannot use this trick on other attributes.
Can someone give me some clues?
