示例1: KeyBinding
KeyBinding

// Return menu accesskey: N or Alt+F.
static int32_t gMenuAccesskeyModifier = -1; // magic value of -1 indicates unitialized state
// We do not use nsCoreUtils::GetAccesskeyFor() because accesskeys for
// menu are't registered by EventStateManager.
nsAutoString accesskey;
mContent->AsElement()->GetAttr(kNameSpaceID_None, nsGkAtoms::accesskey,
accesskey);
if (accesskey.IsEmpty())
return KeyBinding();
uint32_t modifierKey = 0;
Accessible* parentAcc = Parent();

if (parentAcc->NativeRole() == roles::MENUBAR) {
// If top level menu item, add Alt+ or whatever modifier text to string
// No need to cache pref service, this happens rarely
if (gMenuAccesskeyModifier == -1) {
// Need to initialize cached global accesskey pref
gMenuAccesskeyModifier = Preferences::GetInt("ui.key.menuAccessKey", 0);
