The previous code was only re-creating the layout properties for these
that had a binding, but that wasn't done if the property was just read,
leading to access to non-existing properties later.
Fixes#2483
This patch merges the changes from #2344 and #2491 and do some cleanup
In particular, this visit the init code expression when visiting the
root element expression
Closes#2344Closes#2491Fixes#2487
If one declare a `property <int> foo;` in Slint, it will be private by
default, and the getter/setter won't be generated, and it may be
confusing as to why
With this change, it still generate private getter and setter so this
gives a better hint to the developer what the problem is.
Replaces #2170
An element with children must be fully inlined or the children array
can't be easily computed.
But the code wouldn't work if the base of a component was not inlined
Just like opacity and other properties, it needs to prevent inlining.
And also add the same warning as for opacity if it is used on the root
(the Window)
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
The const detection for two way binding was not detecting change if one
of the property was set to a const value in a component using it.
This would cause the compiler to generate call set_content on one of the
property in a two way bindings, and later, the "const sentinel" be
present in the dependency list, causing crash.
To avoid segfault for similar bug in the future, added added an assert!
in the property system to detect that.
Fixes#2185
If the last position expression is invalid due to an unrelated error,
the code that tries to do the interpolation was panicking with the
message "The last should never be invalid". (Because it assumed that
invalid meant that it was not set, and we added a 100% for that last
one if it wasn't set. But if it is set and invalid, this would error.)
The component properties might be accessed through different paths so we
may still reach a case where we have to borrow something that is already
borrowed
The property set by the user was not kept because the binding went the
wrong way.
Also remove the undocumented (and equaly not working)
TabWidget::current-focused property from the public API.
The current-focused property is initialized by the tab.
This type is poorly implemented and not documented. Let's remove it for now.
It shall remain available in the git history in the event of a resurrection.
This uses the approach discussed in Mattermost: The compiler understands
a SLINT_DEFAULT_FONT environment variable that can point to a path,
which overrides the fallback font that would otherwise come from the
system (and differ between test systems).
This is technicly a breking change. But this is also a bug and it was only
allowed since 0.3.2, so it is probably fine.
The problem is that any property access to a global was considered as being
local.
Now, change that so that property access to a global object is no longer
local, and other components can't access private property anymore
This reverts commit 000d95670b and commit
d764796e0c to fix arm cross build and
x86-64 linux.
Let's use the core::ffi types when fontconfig-sys switches to it.
Make sure this is the actual builtin type we are looking at and not a
re-defined component
Doesn't work for ListView unfortunately because ListView is not a
builtin type
CC #861
The previous code did not remove two ways binding that were between two
globals. Now we do the remove_aliases pass over the whole document at
once which allos to simplify aliases between globals.
When doing builds that require image embedding (such as for WASM), it's crucial
to also visit the globals (after they've been collected) to catch all image references.
