Changelog

All notable changes to this project are documented in this file.

Unreleased

Changed

Added

Fixed

• Fixed crashes with the Qt backend in release mode.
• Fixed panic when drop-shadow is used in a ListView

0.2.2 - 2022-05-04

Changed

• On wasm, the input event are handled via a hidden <input> element, allowing the keyboard to show on mobile platform
• The size of the window is kept when reloading a window in the preview (instead of being reset to the preferred size)
• Minimum rust version is now 1.59

Added

• Support for keyboard focus with the tab key
• Support more keyboard shortcut in the editing element

• Added VecModel::set_vec to replace the entire contents with new data.
• Added a cache-rendering-hint boolean property that can be applied to any element, to hint to the renderer that it should cache the element and its children into a cached layer. This may speed up rendering of complex sub-trees if they rarely change.

0.2.0 - 2022-02-10

This version changes some APIs in incompatible ways. For details how to migrate your application code, see the C++ migration guide as well as the Rust migration guide for the sixtyfps crate and for the slint-interpreter crate.

Changed

• Minimum rust version is now 1.56
• C++ compiler requires C++20
• In the C++ interpreter API std::span is used for callbacks arguments, instead of sixtyfps::Slice
• Model::row_data will now return a Option<T> / std::optional<T> instead of a plain T.
• Model::model_tracker no longer has a default implementation.
• The deprecated methods Model::attach_peer and ModelNotify::attach were removed.
• The interpreter does not differentiate anymore between Value::Array and Value::Model everything is a Value::Model, which now contains a ModelRc
• In Rust, slint::SharedPixelBuffer and slint::SharedImageBuffer now use a u32 instead of usize for width, height and stride.
• In Rust and C++, slint::Image::size() now returns an integer size type.
• sixtyfps::interpreter::CallCallbackError was renamed to slint::interpreter::InvokeCallbackError
• Some deprecation warning in .60 became hard errors
• Replace ModelHandle with ModelRc
• slint::interpreter::ComponentInstance in Rust now implements slint::ComponentHandle. This removes sixtyfps_interpreter::WeakComponentInstance in favor of slint_interpreter::Weak<slint_interpreter::ComponentInstance>.

• The animation loop-count property was replaced by iteration-count (which is the same as loop-count plus one)

Added

• TextEdit::font-size and LineEdit::font-size have been added to control the size of these widgets.
• Added slint::Window::set_rendering_notifier to get a callback before and after a new frame is being rendered.

0.1.6 - 2022-01-21

Changed

• Breaking: The internal key code for the keys left, right, home and end has changed. This was undocumented, but if you were handling this in the FocusScope event, these keys will now be ignored. Use the Keys.LeftArrow and other code exposed in the Keys namespace instead.
• For sixtyfps::Timer (C++ and Rust), it's now possible to call restart() after a timer has been stopped previously by calling stop().
• Property access in .60 was optimized by doing more constant propagation.

• Added ability to access elements of a model with the [index] syntax.

Fixed

• Native style: Colors are updated automatically when the Windowing system switches to and from dark mode (#687)
• Ctrl/Command+X in text fields copies the selected text to the clipboard and deletes it (cut).
• Improved native ComboBox look.
• Fixed panics or compilation error when using two way bindings on global properties.

0.1.4 - 2021-10-22

Changed

• The ScrollView's default viewport size is no longer hardcoded to 1000px but depends on the contents.

• Don't panic when using a self assignment operator on an invalid type - this produces a compiler error instead.
• Fixed angle conversion for values specified in radians, gradians and turns.
• Fixed SharedVector sometimes not allocating big enough storage.

Changed

• Layouts are now conceptually their own elements, meaning that the x and y properties of items within layouts are relative to the layout and no longer to the parent element of layouts.
• The default spacing and padding of layouts is now 0 instead of being specific to the style. There are now HorizontalBox, VerticalBox, GridBox widgets which have default spacing and padding.
