- Reconfigured subclass creation, as there was a
subtle-but-big-when-it-hit bug in the prior method where bridge
callbacks would lose context of the appropriate delegate when calling
the trait method. The new approach found in `src/foundation/class.rs`
maps and caches subclass creation, and subclasses are now more
apparent when debugging from the Objective-C side as we can carry
their intended name/usage through. Not applied to all yet, but
eventually.
- Cleaned up a number of linter warnings that had grown over time.
- Delegate traits now require an associated const `NAME`, which is used
for subclass creation.
- (macOS) Toolbars now supported setting selected items, which is
typically used in preferences screens.
- (macOS) Windows now support setting the toolbar display style. On Big
Sur, this works as intended - it's a noop on older OS's that don't
support it.
- Support for system icons for macOS preferences windows.
Still a bit to go to flesh this all out, but it's getting there - at
which point then iOS supoort can be folded in easier.
- Added support for Image
- Added a QuickLook feature, to enable thumbnail generation.
- Added support for NSButton.
- Fixed a bug where App activation under Big Sur would leave menus
without the ability to be used.
- Added the ability for Buttons and ToolbarItems to execute callbacks.
- Added support for Labels and TextFields.
- Added support for MenuItems to have callbacks as well.
- Preliminary ListView support; you have to cache your ListViewRow items
yourself for the time being, but it works.
- Animation support for ListView operations.
- Support for ScrollViews.
- Helpers for dispatching actions to the main thread (for UI work).
- Updated the Dispatcher trait to make thread handling simpler.
- Basic font support.
