After clicking Analyze -> Cppcheck (Current Project), the Cppcheck tool view opens, but it's empty and does not say that anylysis is in progress which is very misleading.
Hi, Alexander. This behavior is caused by internal logic of StatusbarProgressWidget, which don't show any progress bar, if job's lifetime is shorter than 1 second. It seems to be a good choice in general, but I agree with you about misleading in some cases like your example :( P.S. I also tried to fix this in https://phabricator.kde.org/D2792 but abandon the revision after discussion.
I didn't complain about the StatusbarProgressWidget's behaviour, what I suggest is to: 1. Add a row saying "Analysis is in progress, expect more problems to come..." into the Problems view, when cppcheck is in progress. 2. Display a message "No problems found." in the Problems view, after cppcheck finished with no output.
