Qt Cocoa Accessibility Overview
Cocoa accessibility is implemented in the following files:
- qcocoaaccessibility (this file) : QCocoaAccessibility "plugin", conversion and helper functions.
- qnsviewaccessibility : Root accessibility implementation for QNSView
- qcocoaaccessibilityelement : Cocoa accessibility protocol wrapper for QAccessibleInterface
The accessibility implementation wraps QAccessibleInterfaces in QCocoaAccessibleElements, which
implements the cocoa accessibility protocol. The root QAccessibleInterface (the one returned
by QWindow::accessibleRoot), is anchored to the QNSView in qnsviewaccessibility.mm.
Cocoa explores the accessibility tree by walking the tree using the parent/child
relationships or hit testing. When this happens we create QCocoaAccessibleElements on
demand.
