void	AddFlutterSemanticsNodeUpdate (const FlutterSemanticsNode2 &node)
	Adds a semantics node update to the pending semantics update. Calling this method alone will NOT update the semantics tree. To flush the pending updates, call the CommitUpdates(). More...

void	AddFlutterSemanticsCustomActionUpdate (const FlutterSemanticsCustomAction2 &action)
	Adds a custom semantics action update to the pending semantics update. Calling this method alone will NOT update the semantics tree. To flush the pending updates, call the CommitUpdates(). More...

void	CommitUpdates ()
	Flushes the pending updates and applies them to this accessibility bridge. Calling this with no pending updates does nothing, and callers should call this method at the end of an atomic batch to avoid leaving the tree in a unstable state. For example if a node reparents from A to B, callers should only call this method when both removal from A and addition to B are in the pending updates. More...

std::weak_ptr< FlutterPlatformNodeDelegate >	GetFlutterPlatformNodeDelegateFromID (AccessibilityNodeId id) const

◆ CreateFlutterPlatformNodeDelegate()

std::shared_ptr< FlutterPlatformNodeDelegate > flutter::TestAccessibilityBridge::CreateFlutterPlatformNodeDelegate ( )

Creates a platform specific FlutterPlatformNodeDelegate. Ownership passes to the caller. This method will be called whenever a new AXNode is created in AXTree. Each platform needs to implement this method in order to inject its subclass into the accessibility bridge.

Implements flutter::AccessibilityBridge.

◆ OnAccessibilityEvent()

void flutter::TestAccessibilityBridge::OnAccessibilityEvent ( ui::AXEventGenerator::TargetedEvent targeted_event )

overrideprotectedvirtual

Handle accessibility events generated due to accessibility tree changes. These events are needed to be sent to native accessibility system. See ui::AXEventGenerator::Event for possible events.

Parameters

[in] targeted_event The object that contains both the generated event and the event target.

Implements flutter::AccessibilityBridge.
