Feature Description

Currently, we have one slint application that has 6 windows and every window has its own global but when these windows have one common state, an instance needs to be stored in every window separately. This creates a problem that once a shared value is changed in Rust, 6 different window needs to update its state. Would be really nice if we can share a global among multiple windows.

Product Impact

We are OTIV, using slint for our Remote Supervision Control solution and we work with multiple windows.

As mentioned in #6235 , we need to design an API in Rust/C++ and interpreter to share global. We could create globals before and have a new_with_globals for example.
