示例1: focusedUIElementForPage
AccessibilityObject* AXObjectCache::focusedUIElementForPage(const Page* page)
{
if (!gAccessibilityEnabled)
return 0;
// get the focused node in the page
Document* focusedDocument = page->focusController()->focusedOrMainFrame()->document();
Node* focusedNode = focusedDocument->focusedNode();
if (!focusedNode)
focusedNode = focusedDocument;
if (focusedNode->hasTagName(areaTag))
return focusedImageMapUIElement(static_cast<HTMLAreaElement*>(focusedNode));
AccessibilityObject* obj = focusedNode->document()->axObjectCache()->getOrCreate(focusedNode);
if (!obj)
return 0;
if (obj->shouldFocusActiveDescendant()) {
if (AccessibilityObject* descendant = obj->activeDescendant())
obj = descendant;
}
// the HTML element, for example, is focusable but has an AX object that is ignored
if (obj->accessibilityIsIgnored())
obj = obj->parentObjectUnignored();
return obj;
