I'm new to ROS and I am trying to develop a GUI with C++, where if a certain YAML file exists a tab in the GUI would be created and the layout of the tab page (buttons, checkbox, etc) and the function (rosrun, roslaunch) all included in the YAML file. I have tried to find tutorials or codes with these functionality but no luck. Anyone has a clue where I can find a tutorial or how to do this?
