Member Function Documentation

DispatchAccessibilityAction()

virtual void flutter::FlutterPlatformNodeDelegate::OwnerBridge::DispatchAccessibilityAction ( AccessibilityNodeId  target, FlutterSemanticsAction  action, fml::MallocMapping  data  )

protectedpure virtual

Dispatch accessibility action back to the Flutter framework. These actions are generated in the native accessibility system when users interact with the assistive technologies. For example, a FlutterSemanticsAction::kFlutterSemanticsActionTap is fired when user click or touch the screen.

Parameters

[in]	target	The semantics node id of the action target.
[in]	action	The generated flutter semantics action.
[in]	data	Additional data associated with the action.

GetLastFocusedId()

virtual AccessibilityNodeId flutter::FlutterPlatformNodeDelegate::OwnerBridge::GetLastFocusedId ( )

protectedpure virtual

Get the last id of the node that received accessibility focus.

GetNativeAccessibleFromId()

virtual gfx::NativeViewAccessible flutter::FlutterPlatformNodeDelegate::OwnerBridge::GetNativeAccessibleFromId ( AccessibilityNodeId  id )

protectedpure virtual

Get the native accessibility node with the given id.

Parameters

[in]

id

The id of the native accessibility node you want to retrieve.

RelativeToGlobalBounds()

virtual gfx::RectF flutter::FlutterPlatformNodeDelegate::OwnerBridge::RelativeToGlobalBounds ( const ui::AXNode *  node, bool &  offscreen, bool  clip_bounds  )

pure virtual

Gets the rectangular bounds of the ax node relative to global coordinate.

Parameters

[in]	node	The ax node to look up.
[in]	offscreen	the bool reference to hold the result whether the ax node is outside of its ancestors' bounds.
[in]	clip_bounds	whether to clip the result if the ax node cannot be fully contained in its ancestors' bounds.

SetLastFocusedId()

virtual void flutter::FlutterPlatformNodeDelegate::OwnerBridge::SetLastFocusedId ( AccessibilityNodeId  node_id )

protectedpure virtual

Update the id of the node that is currently foucsed by the native accessibility system.

Parameters

[in]

node_id

The id of the focused node.
