Indeed, on the Measures tab (the first one), there's no filter. This means that once you've started filtering (using filters in other tabs), there's no way to come back to the code itself (except if you click "Show Full Source").
Files normally have the "ncloc_data" measure (see documentation for this metric to se how to use it). This makes it possible to create 2 filters:
- When clicking on this filter, it just shows the full source code
- Then we can wonder if the "Show Full Source" action is still needed (if not, then we should add a tooltip on the "Lines" filter to tell that it shows the full source)
- Lines of Code
- Shows only the lines of code, i.e. the lines identified by the "1" value in the "ncloc_data" measure
- If the "ncloc_data" measure is null or empty on a file, this filter should not be available
