- Check `CanFocus` in `FocusManager.SetFocusedElement`
- Check for `IsEffectivelyVisible` in `CanFocus`
- Clear focus when control made invisible
- Update tests that relied on unfocusable controls being focused
One shouldn't call `ClearContainer` on a container that is an item. Adjusted `SelectingItemsControlTests` because selection is actually maintained on move with containers hold their own `IsSelected` state.
Fixes#11128
Which exposes the resize reason and new client size. Required renaming `PlatformResizeReason` to `WindowResizeReason`. Made `TopLevel.HandleResized` method internal.
Allow overriding the default behavior of item containers in styles or in `ItemContainerTheme`. To do this, use `SetCurrentValue` to set the properties, only if the properties are not already set (i.e. from a style). This also requires us to clear the current value when the container is cleared (styles won't be affected as `AvaloniaObject.ClearValue` only clears local or `SetCurrentValue` values).
Makes the `StyledElement.Classes` and `Flyout.FlyoutPresenterClasses` properties readonly. Adds a transformer to the XAML compiler to convert attribute syntax classes setters to collection syntax so that they will be added to the existing `Classes` object.
Prevents an unneeded allocation of a `Classes` object when setting `Classes` from XAML.
Rather than using the `ISelectable` interface to communicate container selection from the `SelectingItemsControl` to the container, use the `SelectingItemsControl.IsSelected` attached property, setting it with `SetCurrentValue` so that bindings defined in a style or item container theme can override the selection. Required an extra virtual `ContainerForItemPreparedOverride` method on `ItemsControl`.
