Development using other frameworks + QML

I am interesting in porting an app written using the JUCE C++ framework to Sailfish. Are there any examples out there of people using different frameworks/languages to build Sailfish apps, and how they solved the issue of calling Qt/QML based native UI methods?

I think for Sailfish to be as accessible and future proof as possible, this would be important - e.g, building a Sailfish app using Rust.

It's quite "simple" (if you pass me the word), really.

SailfishOS runs on wayland, which means the (wayland) client (read : application) is responsible for rendering into a buffer provided by the Compositor itself.

I'd say (and these are my 2 cents), if the language you want to write the app in does support OpenGL, use that. It should be enough; of course you will need to manage input as well, so as long as you can hook on the /dev/input/?? devices you should be fine (assuming the language might even provide APIs for that). If the language does not have support for OpenGL, you need to write a wayland client for it (qt5-wayland I believe is the module used by QT and a good example to start with).

OK, sure, I can draw onto an OpenGL context, but what about "native" UI elements provided by SailfishOS? I think its important to preserve the "look and feel" of the platform.

You'd need bindings into QML from your language; IIRC the stack would then be : QT -> QML -> #your_fav_language_here#

EDIT : i guess another option would be to only bind into the style objects of the qt/qml stack.

Thanks - are there any examples of such bindings anywhere?

@adamski : google is your friend, but IIRC gtk and pascal should have qml bindings..
