Refactor the code in the compiler a bit to allow using the
`TypeLoader` for the root document itself and use that in the
interpreter.
You need to run passes *before* the `TypeLoader` takes ownership
of the Document, so the `load_file` in `TypeLoader` needed a bit of
changing.
We need to decorate an Element so we can interact with it. I want
to decorate only *one* instance of a repeated element to avoid
cluttering up the screen. So pick one good candidate for decoration:
Ideally the one the user clicked on, got for the first one
otherwise.
Store this information so we can get it back after re-rendering,
and so that we can actually mark newly added elements for selection
after they get rendered.
They are not commonly used so no need to use semi-public api for that
and it's really easy to similate with ust two clicks anyway
The previous test function were added before there was public way to
send events
The preview can not leave it up to the interpreter to handle element selection
and highlighting. So add new functions to the interpreter (behind the
"highlight" feature-gate) to query positions of elements.
This exposes some of the code that is used by the existing highlighting code
and extends it where needed.
Two use-cases need to be covered:
1. Query the positions of a component (given by source file path and offset).
This is then used to highlight all occurences of a component as the
cursor position in a source file changes.
2. Query the position of an element (given as `ElementRc`).
This is used when selecting elements in the UI. We need to work at
the element level for this, not at the component level.
Also make the `highlight` module public but feature-gated, so that we
can put helper-types there.
A None value means the file on disk is the golden version.
We have an editor, the LSP and the preview that all need to at least
notice when they have newer data then their peers. So IMHO it makes
sense to have an optional document version around.
The language server protocol makes use of a version number already. This
patch moves that code into the compiler so that it is stored with the
actual data getting versioned.
... and use it to hide internal functionality so users will notice that
they depend on fucntionality we do not provide any guarantees for.
Make the lsp and viewer request the internal feature when building the
interpreter.
This is used in slintpad to map relative image URLs to their real
download locations.
This has the side-effect of removing the service worker.
Fixes: #2905
and their related name.
Also move the component module in the item_Tree module
register_component -> register_item_tree
ComponentItemTree -> ItemTreeNodeArray
For #3323
Rationale from that issue:
Right now, we use the term `component` in the Slint language and in the compiler to be a a tree of elements that can be used as an element in a .slint file.
The term is also currently used in the runtime as a tree of runtime Items that are allocated together. (declared in ComponentVTable)
But there are no 1 to 1 mapping between a `component` in the slint language, and a runtime Component.
(for example, the items behind a `if` or `for` or `PopupMenu` are in a different runtime component. And `component` declared in Slint are often inlined)
So we should rename the internal runtime `Component` to `ItemTree`
The currently public `slint::ComponentHandle` wraps the "root" of the ItemTree, but that's ok because it is generated from a .slint `component`, so it doesn't change name

* Configure clippy to not report about type complexity until *much*
later
* Configure clippy to only complain about more than 10 function
arguments
* Properly format safety sections
* Allow unnecessary main functions in doctests in the slint API crate
* AccessKit: Move big block of code before if condition
The main change is that the window adapter is not copied into
sub-components anymore - instead it is accessed through the root. This
is especially important for globals.
In order to add the root, a little extra dance had to be performance on
instantiation: The self_rc/self_weak is created first and the
ComponentExtraData's fields are populated via once_cells.
Consume the Rc in the function signature where the implementation would clone it anyway.
This is also needed in preparation for InstanceRef::window_adapter()
walking up the tree of components,
by which it's not possible to return a reference anymore as
parent_instance() returns a new lifetime that's shorter than &self
inside window_adapter().
This includes slint-viewer, slint-interpreter (when loading path, not
string), slint-compiler.
(This would also include internal things such as
`import { Xxx } from "foo.rs"`, if we didn't check for .slint or .60
extension before)
But that doesn't include anything that's not opening the source by path
(so not the lsp which use its own representation coming from the editor,
or varius tools like the updater and fmt which also open the files
themselves)
* compiler: Make mapping from source offset to line/column more reusable
* compiler: Improve mapping of offset to line/column
* Fix unit tests after line mapping update
* interpreter: Add code to have a element picker mode
* slintpad: Add picker mode to the preview
* slintpad: Do not try to highlight "empty" highlight requests
* Slintpad: Cycle through all the possible elements in design mode
* Slintpad: Ignore builtins and eat less clicks
* Slintpad: Highlight the element selected in design mode
* Slintpad: Do not use static mut variable in design mode
* slintpad: Rename `set_current_element_information_callback`
* Interpreter: Do not use unsafe in design mode code
Done with: @ogoffart and @tronical
Add explicit enum values for repr(C) enums that have attributes like
cfg, so that even if there's a cfg gap in an enum (say cfg(feature =
"svg")) it won't break the ABI.
