Show missing interface method implementation as error in project view

Hi there,

>So the implementing class will be marked the same way like when you make a typo...

It's not a typo there. Typo is Spellchecker-related and has lowest severity/priority. What you see there is a parser error (highest severity), which is serious and not suppressible hence it's shown even in Project tree.

But in general:

• https://youtrack.jetbrains.com/issue/IDEA-96288 and related tickets
• Have you tried using "Code | Inspect Code..." to get a list of all issues in the file/folder/project?

Yes you are correct about the parser and thank you for the pointers to Inspections.

When i do "Code | Inspect Code" i get the error in the inspection results. However I like to have these errors visible in the project tree structure because it's more visual (and am used to it from other IDE :) )

I tried to change the inspections based on the error i get from Inspect Code, however even if i set it as Error, it's not underlined in project view.

Setting:

Based on this error:

No idea what else to set as error to make this work ...

• Only the highest (Parser/Lexer level -- which means file cannot be properly parsed as there is serious syntax error / file is invalid) errors show such highlighting in the Project tree.
• The errors reported by actual Inspections (when file syntax itself is correct but there are logic errors that may lead to runtime error/prevent execution) have lower severity than that (even though they also shown as "Error"). The aforementioned ticket is about that -- to be able to use error highlighting in Project tree even for Inspection based issues.

I've mentioned "Code | Inspect Code" as possible alternative for time being -- if you need to see all serious errors it allows you to see all of them + in one place.

The benefit is: it analyses your file even if it's not currently opened / was opened recently.

With error highlighting in Project tree -- if you do not have that file open (so IDE does not really know about those issues) it will not highlight that file -- at very least that's how it works for CSS files (e.g. imaging some 3rd party .css file that uses some browser hacks or alike that IDE is unaware/fails to accept as valid. As long as I do not open such file in current session IDE does not show any red underwaves for that file. But once I have to open it -- that annoying/distracting for me highlighting is shows (annoying as I cannot resolve it myself -- that code must remain as is)).

Ok, that makes sense. Thank you for your answers!

I'll use the Inspections results for now.
