Electron Version

What operating system are you using?

Other Linux

Operating System Version

OpenSuse or any other

What arch are you using?

x64

Last Known Working Electron version

No response

Expected Behavior

How can I set a custom WM_CLASS attribute to windows opened with electron? For example, in chromium is possible specifying --class argument. When app get a WM_CLASS, KDE and other desktops can correctly assign a icon based on .desktop files installed.

google-chrome --app=https://example.org --class=crx_application

Is there any way to do this in electron? Maybe with command line or with javascript? Something like this could be good

const window = new BrowserWindow({wmClass: "crx_appplication"})

Actual Behavior

I don't see any option related to this. Is there any way to get this?

I have found a solution for this from javascript side.

const app = require('electron').app;
app.setName("crx_appplication");

the above code will set the WM_CLASS to crx_appplication

It would be nice to have a command line parameter though.

there you go

For example, in chromium is possible specifying --class argument.

Some other applications use --name, but --class seems to be more common.

I can confirm that the suggestion by @Jagadeesh19 works:

// In electron main script
electron.app.setName("Your App Name / WM_CLASS");

Thus the issue "There is no way to get a custom WM_CLASS on electron app Windows" can be considered resolved (unless someone needs a WM_CLASS that explicitly differs from the app name).

If someone wants to customize the WM_CLASS through command line parameters, then why don't you add/parse a custom command line parameter, which is then used in electron.app.setName(...)?

Yes to a "WM_CLASS that explicitly differs from the app name" and in any case without the command line parameter (that already exists in Chromium) you cannot change it on the fly.
