示例1: ProcessTextSelChangeEvent
void SelectionManager::ProcessTextSelChangeEvent(AccEvent* aEvent) {
// Fire selection change event if it's not pure caret-move selection change,
// i.e. the accessible has or had not collapsed selection.
AccTextSelChangeEvent* event = downcast_accEvent(aEvent);
if (!event->IsCaretMoveOnly()) nsEventShell::FireEvent(aEvent);
// Fire caret move event if there's a caret in the selection.
nsINode* caretCntrNode = nsCoreUtils::GetDOMNodeFromDOMPoint(
event->mSel->GetFocusNode(), event->mSel->FocusOffset());
if (!caretCntrNode) return;
HyperTextAccessible* caretCntr = nsAccUtils::GetTextContainer(caretCntrNode);
NS_ASSERTION(
caretCntr,
"No text container for focus while there's one for common ancestor?!");
if (!caretCntr) return;
Selection* selection = caretCntr->DOMSelection();
// XXX Sometimes we can't get a selection for caretCntr, in that case assume
// event->mSel is correct.
if (!selection) selection = event->mSel;
mCaretOffset = caretCntr->DOMPointToOffset(selection->GetFocusNode(),
selection->FocusOffset());
mAccWithCaret = caretCntr;
if (mCaretOffset != -1) {

new AccCaretMoveEvent(caretCntr, mCaretOffset, aEvent->FromUserInput());
nsEventShell::FireEvent(caretMoveEvent);
}
