/*!
|
|
This module contains the builtin items, either in this file or in sub-modules.
|
|
|
|
When adding an item or a property, it needs to be kept in sync with different place.
|
|
(This is less than ideal and maybe we can have some automation later)
|
|
|
|
- It needs to be changed in this module
|
|
- In the compiler: builtins.slint
|
|
- In the interpreter (new item only): dynamic_item_tree.rs
|
|
- For the C++ code (new item only): the cbindgen.rs to export the new item
|
|
- Don't forget to update the documentation
|
