This exposes FocusReason to .slint, and adds it as an argument to focus-event-changed callback on FocusScope to close#8387. It also adds two new callbacks, focus-gained and focus-lost, which are identical to focus-event-changed but are only invoked on focus gain or loss respectively.
In addition to this, it removes the FocusEventReason::AccessKit variant, replacing it with the mouse variant to hopefully make AccessKit more compatible with any Slint code that will use FocusEventReason.
Finally, I added two tests based on focus_change_event.slint, one for testing the FocusEventReason argument and another for testing the new callbacks.
close#8387
ChangeLog: Added `focus-gained` and `focus-lost` callback to FocusScope. Pass an `FocusReason` enum to the FocusScope callbacks
Closes#5992
Adds the enum FocusEventReason and makes it an argument for FocusEvent. This reason could eventually be exposed in Slint to solve #8387.
Using the focus reason tracking, I also added a select all on keyboard focus for TextInputs (except on macOS), which should close#5992.
ChangeLog: TextInput selects its content when focused with the keyboard on Windows and Linux
We currently forward declare classes as we use them in functions.
But this breaks if classes with the same name were declared in the
parent namespace. As shown with this example
```C++
// Uncomment that line to make the code break
//struct SharedGlobals;
namespace ns {
// Is that a forward declaration in `ns`?
// Depends if it was declared before in the parent namespace
void foo(struct SharedGlobals *x) {}
// Actualy define ns::SharedGlobal
struct SharedGlobals { int x; };
int xyz() {
SharedGlobals globals;
foo(&globals);
}
}
```
So make sure we forward-declare the classes properly to be more robust
and be able to include generated file with namespace after a file
without namespace
CC #2909
The code would fail to compile because the property would not be seen as
used and would be removed, but not the change callback.
Fixes#8269
Also fix a segfault in the added test because it will initialize the
change callback (and therefore query the properties) because the
SharedGlobal structure is fully initialized.
So we must only initialize the change callback on global after the
SharedGlobal is fully initialized
... by changing the resolution for the `WindowItem` to traverse the
item tree from the current item, instead of going to the window.
This doesn't quite fix#4298 because `rem` resolution is still missing.
That requires the built-in default font size function to be fixed as
well, which is non-trivial.
cc #4298
Conversion from negative float to unsigned is saturating to 0 in rust
and undefined behavior in C++, we should therefore handle the case
properly
Fixes#8222
This does some refactoring to allow builtin item functions to return a
value:
- builtin member functions are no longer BuiltinFunction, but they are
just normal NamedReference
- Move special case for them in the LLR/eval
Right now we always `lock().value()` it which is the equivalent of
`upgrade().unwrap()` in rust, this helps because it keeps the parent
alive when we are calling function in it.
Ideally we should also check that it wasn't deleted, but that's another
issue.
Fixes#7880
Adds methods to change a `string`'s case to lowercase or uppercase.
They use Rust's `to_lowercase` and `to_uppercase` `String` methods.
ChangeLog: Added string.to-lowercase and string.to-uppercase
Closes#7860
Add two new float to string conversion methods that mimic
JavaScript's Number.toFixed() and Number.toPrecision().
They are implemented as no_mangle functions similar to the already
existing float to shared string conversion.
Closes#5822
There was an image like this:
```slint
height: 40px
Image {
width: parent.width;
height: self.source.height * 1px;
source: @image-url("....");
}
```
The `y` propery ended inlined like so:
`(40 - the_image.source.get().size().height)/float(2)`
but since height was `unsigned` the C++ rules means that the operation
happens as unsigned and we have an overflow. and `y` turned out to be
very big instead of slightly negative (for image whose height was larger
than 40)
This is required to fix closing popup with the Qt backend, as we use the
window_adapter as a hack to get the root window_adapter (as opposed to
the popup one)
(That function was only used for the ComponentContainer and was not
implemented for C++ before)
Note that this reinterpret a
`Option<slint::private_api::WindowAdapterRc>` to just a `WindowAdapterRc`
This is because `Option` is only forward declared in C++ as it is not
generaly `#[repr(C)]`, but we assume (and assert) the usage of a niche.

`__CARGO_FIX_YOLO=1` is a hack, but it does help a lot with the tedious fixes where the result is fairly clear.

Otherwise initializing the translation won't work.
This can't be tested because the testing backend is always initialized before.
And also hasn't been a problem on MCU where the feature is the most usefull
because it also uses custom backend there initialized before

This would avoid for example using a sub-component index in an array of
instances or items.
It also self-document what the index is for.
There are still a couple of cast from repeater-index to u32 because we
do some hack with the repeater-index number for component containers
We also cast back to numbers in order to convert it to string in the
generated code.
Because we set the viewport-width several time to different value during
the layouting of the ListView, it will cause this property to always be
dirty. In particular, this causes permanent restart of the fluent's
scrollbar animation on the size of the handle, causing continous
repaints.
Introduce two new properties for string in .slint:
- .is-empty: Checks if a string is empty.
- .character-count: Retrieves the number of grapheme clusters
https://www.unicode.org/reports/tr29/#Grapheme_Cluster_Boundaries
These additions enhance functionality and improve convenience when working with string properties.
Only the interpreter is implemented so far
MacOs won't work yet because we don't disable the default winit menubar
The viewer don't support removing the MenuBar yet
Popups are stored in a HashMap and are assigned an ID so popup.close(); closes the correct popup and so a single PopupWindow cannot be opened multiple times
This currently doesn't have public API to enable it yet.
