As outlined in #2199, there may be ways to trigger text layout code
through forward-focus before embedded fonts are registered. To fix this,
this patch replaces the init_code vector, which had the SetFocusItem
code before the font registration, with three explicit vectors for focus
setup code, code from init callbacks, and initial focus, and defines the
order in one central place in the copmiler (iter()).
Fixes#2199
Commit 24dcef5fed added a warning for the
implicit export of last component. For 1.0, this commit makes it so that
the root component is determined by the last export in the file.
Replace the intermediate NamedExport and SeenExport structs and the hash
table to find duplicates with a simpler algorithm:
1. Collect all exports into a vector, sorted, with duplicates
2. Eliminate duplicates and issue warnings accordingly and insert the
result into a second vector.
As a bonus, the resulting vector of exports is now sorted.
This is not supported right now, the other elements will not be part of
the layout, and two `for` will be in the same listview, creating bad
situation with the scrollbar.
This is a warning since it would be a breaking change to make it an
error.
For example, we used a FocusScope in the StandardListView implementation so
I had to go trough one level of indirection

These are two different concept, and it is confusing to keep them in the
same enum
We want to support component without any base element, and Void is
already used for global component, so do this refactoring before
- We should not panic if the base type is invalid
- We should try to keep bindings in the Element even if the base type
is invalid
- Fix querying the element at a position in case it is not in the last
component of a file
Implement basic accessibility (a11y) support, using the Qt backend.
_This should get us started, but accessibility support is an additional way to interact with UIs that is very different from the "graphical way" most users will interact with the UI. No single PR will "make a toolkit accessibility", this needs to be an ongoing effort!_
Parts of this PR:
* Add functions to access a11y-related properties to Component
* Add helper functions to Item struct
* Handle accessible- properties in the compiler
* Add documentation, add description, enforce some basic rules
* Make the Text element accessible by default
* Don't optimize away accessibility property in the LLR
* Ensure that accessibility property are marked as used
* Add some accessibility properties to the native style widgets
* Support for bool and integer `accessible` properties
* Implement basic support for accessibility
* Make basic widgets accessible by default
* Make slider focus-able and interactable with keyboard
* Tell a11y layer about value changes
* Generate QAccessible constants using bindgen
* Don't expose the `accessible` properties when using the MCU backend: There is no backend to make use of them
* Handle focus change based on keyboard focus of the window
* Report accessible widgets at correct positions
* Allow for (virtual) focus delegation at the a11y level
* Calculate value step size dynamically
* Make sure to not send notifications to a11y backend about dead objects
* Make sure that the compiler don't panic if the parent of a PopupWindow
is optimized (by not optiizing such element)
* Ensure that we can call popup.show() from within a deeper repeater
* Ensure that the parent element of the popup is the right one in case of
repeater (and not the node in the parent component)
This partially revert ad5991f8fa and
6c7a7aed0e because we must do the lower_popup
adter the repeater pass, because otherwise the parent element of the
created component for the PopupWindow might be wrong and it is not easy to
adjust (we would have to make Component::parent_element a RefCell or duplicate
it again.
Fixes#1132
* The LLR expect that the popup_window is actually contained in it's parent
component popup_windows, otherwise the context is not correct.
* There is no index property for a PopupWindow
Fixes#1113
The problem is that if some bindings are coming from already inlined elements
they should have a higher priority field, so that whenmerging the two way
binding, we keep the least deep value
Fixes: #1026
Enable with `SLINT_EMBED_GLYPHS=1` and select sizes like
`SLINT_FONT_SIZES=12,16`
This change just puts the data structures in place, rasterizes a fixed
subset, embeds that into the rust generated code and calls a backend
function for registering the font that is unimplemented.
