Created attachment 147099 [details] Screenshots and basic project SUMMARY *** If you have your header and cpp in a namespace, the auto complete (ctrl+space) to add the implementation of functions to the cpp file does not work properly. *** STEPS TO REPRODUCE 1. Create header and cpp file 2. Add namespace around header and cpp 3. Add declaration of function to header 4. invoke autocomplete inside namespace (broken) 5. invoke autocomplete outside namespace (working) OBSERVED RESULT 'implement function' does not show when autocomplete is invoked inside the namespace EXPECTED RESULT 'implement function' should show in autocomplete normally SOFTWARE/OS VERSIONS Linux: Ubuntu 20.04 Qt:5.15.8
