Globals in c++ (no global<T> function?)

[mathisloge]

I wanted to follow the advice in https://docs.slint.dev/latest/docs/slint/guide/language/coding/globals and use a global like app->global<Logic>().... However I can't find a templated function global<T> in the c++ sources.
As a workaround I can use the public variable globals.

Are the docs wrong here or is it missing in the public API?

[ogoffart]

The global<T>() accessor is generated, but only for globals that are exported (or re-exported) from the main file

 // in your main .slint file:
 export { Logic } from "logic.slint";

Then app->global<Logic>() will be available in the generated header.

Please don't use the globals member you found, it's an internal implementation detail of the generated code, not part of the public API. It can change or be renamed at any time without notice. Always go through global<T>().

Working C++ example in the repo: https://github.com/slint-ui/slint/blob/master/demos/printerdemo/cpp/main.cpp printer_demo->global<PrinterQueue>()

Ah, thank you!

re-export a global from the file also exporting the main application component.

I think this section in the docs would benefit from some highlighting or the example you have given.
