Hello,
My doubt is, If I want to write a ros node using qt GUI- Is it necessary to follow rqt plugin cpp tutorial(I mean is it necessary to create a plugin) or is it possible to write a node and add cmakelist.txt as here http://answers.ros.org/question/10377/looking-for-an-existing-ros-qt-example/ "this". A small example to which opens a qt window is very helpful. Many thanks in advance.
