示例1: AccTextSelChangeEvent
void
SelectionManager::ProcessSelectionChanged(nsISelection* aSelection)
{
Selection* selection = static_cast<Selection*>(aSelection);
const nsRange* range = selection->GetAnchorFocusRange();
nsINode* cntrNode = nullptr;
if (range)
cntrNode = range->GetCommonAncestor();
if (!cntrNode) {
cntrNode = selection->GetFrameSelection()->GetAncestorLimiter();
if (!cntrNode) {
cntrNode = selection->GetPresShell()->GetDocument();
NS_ASSERTION(selection->GetPresShell()->ConstFrameSelection() == selection->GetFrameSelection(),
"Wrong selection container was used!");
}
}
HyperTextAccessible* text = nsAccUtils::GetTextContainer(cntrNode);
if (!text) {
NS_NOTREACHED("We must reach document accessible implementing text interface!");
return;
}
if (selection->GetType() == nsISelectionController::SELECTION_NORMAL) {
nsRefPtr<AccEvent> event = new AccTextSelChangeEvent(text, aSelection);
text->Document()->FireDelayedEvent(event);
} else if (selection->GetType() == nsISelectionController::SELECTION_SPELLCHECK) {
// XXX: fire an event for container accessible of the focus/anchor range
// of the spelcheck selection.
text->Document()->FireDelayedEvent(nsIAccessibleEvent::EVENT_TEXT_ATTRIBUTE_CHANGED,

}
}
HyperTextAccessible* text = nsAccUtils::GetTextContainer(cntrNode);
if (!text) {
// FIXME bug 1126649
