#2 The Interface does not set WM_CLASS

[c00kiemon5ter]

On Linux the interface does not set the WM_CLASS property.
This can be easily checked with `xprop`. Use like:

1. open cm-grace
2. run:
xprop WM_CLASS
3. select the cm-grace window

no information is returned.

To set WM_CLASS one must create an XClassHint struct
and fill the res_name and res_classs members.

I do not know my way through the cm-grace source code,
based on some grepping, I think the right file to patch is 'src/juce_amalgamated.cpp'.

I set out to create a patch, but when I realised that the build system is not
what I expected it to be (I couldnt get premake.lua to work) I gave up.

Something along the lines of the attached patch should do it (untested..).
The allocated memory should be free'd with 'XFree(..)'

Your approach to solving the issue is the most valuable part, and your patch gives the maintainers a clear direction. They can likely integrate your logic much faster than if they had to debug the issue and write the code from scratch. cookie clicker

I totally get where you’re coming from with the WM_CLASS Run 3 issue! I struggled with interface inconsistencies too when working on my projects. It’s such a hassle when things don’t sync properly. Have you thought about how this impacts usability in collaborative settings? Let’s brainstorm solutions together!

I totally relate to the WM_CLASS issue! In my own project, I had a similar bug that made integrating with window managers tricky. Sorting it out made my workflow so much dashmetry smoother—hope you get this fixed soon!
