* iOS: Don't invalidate a11y whenever UI elements are added or removedTor Arne Vestbø2023-06-071-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The UIAccessibilityScreenChangedNotification will result in iOS resetting its state, focusing the first a11y element on the screen. We shouldn't tie clearing the a11y cache to this notification, as those are two separate actions. In the case of adding or removing individual elements, we still likely need to clear the cache, but can inform the system of the more granular UIAccessibilityLayoutChangedNotification to have it re-read the a11y tree. We still handle additions and removal of a11y elements with Window or Dialog roles as UIAccessibilityScreenChangedNotification, as these likely involve major UI changes. The implicit UIAccessibilityScreenChangedNotification on QIOSWindow destruction has been removed, as it's assumed iOS will automatically refresh its a11y tree when a UIWindow is destroyed, and in any case it's up to the individual clients of QAccessible to send the relevant QAccessibleEvent to inform about the situation.

* iOS a11y: Ensure parent elements are stacked below their childrenTor Arne Vestbø2022-12-151-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The accessibility system on iOS does not support elements that are both accessible themselves, and act as a container for other elements. You either return YES from isAccessibilityElement, which allows you to report accessible properties for the element, or NO, in which case you can implement the informal UIAccessibilityContainer protocol to report child elements. This was confirmed in Apple Q&A session on accessibility December 14. As Qt's accessibility system allow elements that are both containers and have properties of their own, we can't build a hierarchy of elements and containers, with only the leaf elements being accessible. Instead, we let each UIView act as a UIAccessibilityContainer, and report the entire child hierarchy as a single level of sibling accessible elements. In doing so, we include elements such as the Window or Dialog that root all the accessible elements. And apparently the order that we report these elements back to iOS determine the z-order of the elements, so we need to ensure "container" elements are behind their children. Otherwise assistive technologies such as Voice Control, or the Accessibility Inspector, will not be able to target the child elements.

* iOS A11Y: Do not add children of invisible parentMike Achtelik2022-03-281-1/+1
| | | | | | | | | | Prevent children from invisible parents from showing up in the a11y hierarchy. This fixes a problem on iOS which e.g. always adds hyperlink children of QML Text items, even if the Item itself is invisible.
