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.
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`.
A lot still broken, in particular virtualization is completely removed.`ItemsPresenter` now no longer has an `Items` or `ItemTemplate` property; it detects when it's hosted in an `ItemsControl`. `IItemsPresenter` interface removed.
Applying styling in the constructor isn't a good idea as demonstrated by #8549..
Instead apply styling when showing a window, or if it's needed call `ApplyStyling` manually, e.g. in unit tests.
Fixes#8549
- Removes the `IStyler` service and the `Styler` implementation
- Moves the logic for applying styles and control themes into `StyledElement`
- Removes the style `TryAttach` method from the public API
- Removes style caching for now - this will need to be added back
Fixes for #8092:
- Always round sizes up, not to the nearest pixel, thereby ensuring that `DesiredSize`s don't get rounded down where possible.
- Apply rounding to `Padding` and `BorderThickness` in measure pass as well as arrange pass, to ensure that `DesiredSize` takes this rounding into account.
When a native popup window is positioned relative to a placement target on
the root window and the root window is moved or resized, the popup position
should update to reflect the new position of the placement target.
If a native popup window is positioned relative to another popup, as in the
case of sub-menus, and the parent popup is moved due to a change in the
position of its placement target, the child popup should also update
relative to the new position of the parent popup.
