How to associate compose desktop app with custom URL scheme? (I want to open it from browser using myapp://)

https://docs.oracle.com/en/java/javase/17/docs/api/java.desktop/java/awt/Desktop.html#setOpenURIHandler(java.awt.desktop.OpenURIHandler)

There will be some extra steps on macOS though.

[Alexander Zhirkevich]

As i know for Windows for example, i need to setup registry key for the application. Is this step required when using OpenUriHandler?

[Alexander Maryanovsky]

I’ve never used this myself, so I don’t know. The docs only mentions macOS, so either it doesn’t work on other platforms, or it doesn’t need an extra setup, or maybe it does after all and the docs just don’t mention it.

[Alexander Zhirkevich]

OK, thanks anyway

[Alexander Maryanovsky]

Also, Conveyor handles it for you, I think: https://conveyor.hydraulic.dev/10.1/configs/os-integration/

[Alexander Maryanovsky]

I see jpackage has --file-associations, but I don’t see anything about URLs.

[Alexander Zhirkevich]

I also looked for jpackage options but didn't find anything either. Only something called jDeploy but i guess it is something different

[Alexander Zhirkevich]

You have a paragraph about it in compose docs 😄 (at least for mac)

[Alexander Maryanovsky]

Let me know if it works on Windows. Keeping my fingers crossed.

[Alexander Zhirkevich]

Doesn't have windows machine to try right now. But there is still requirement to modify windows registry to do it. It seems there is no similar gradle option like for mac info.plist but for windows registry :(

[Alexander Maryanovsky]

Maybe the JVM does it when you first run the app, or maybe there’s some other mechanism; I’m not sure.

[Alexander Zhirkevich]

Yep, registry can be modified manually at runtime so there should not be a problem i guess

@Alexander Zhirkevich Conveyor uses the "new" Windows way to do things, which doesn't involve registry keys. It's more macOS like, you have an XML file that describes OS integration points.

[mikehearn]

So if you use that you can just add app.url-schemes = [ my-app ] to your config and then your app is launched for my-app:// urls.

[Alexander Zhirkevich]

Ok, thanks, I’ll try it

[Alexander Zhirkevich]

Looks like it ts not free, right? :)

[mikehearn]

Free for open source apps.

@Alexander Zhirkevich Did you find a way to make it work for all platforms? Because if im not wrong setOpenUriHandler is only for mac?
