The way GTK/Gail/ATK work is that 58 they create accessibles for all objects on startup. 59 In order to avoid querying all the objects individually via DBus 60 they get sent by using the GetItems call of the cache. 61 62 Additionally the AddAccessible and RemoveAccessible signals 63 are responsible for adding/removing objects from the cache. 64 65 Currently the Qt bridge chooses to ignore these. 66 */ 67 QSpiDBusCache(QDBusConnection c,QObject * parent)68QSpiDBusCache::QSpiDBusCache(QDBusConnection c, QObject* parent) 69 : QObject(parent) 70 { 71 new CacheAdaptor(this); 72 c.registerObject(QLatin1String(QSPI_OBJECT_PATH_CACHE), this, QDBusConnection::ExportAdaptors); 73 } 74 emitAddAccessible(const QSpiAccessibleCacheItem & item)75void QSpiDBusCache::emitAddAccessible(const QSpiAccessibleCacheItem& item) 76 { 77 emit AddAccessible(item); 78 } 79 emitRemoveAccessible(const QSpiObjectReference & item)80void QSpiDBusCache::emitRemoveAccessible(const QSpiObjectReference& item) 81 { 82 emit RemoveAccessible(item); 83 } 84 GetItems()85QSpiAccessibleCacheArray QSpiDBusCache::GetItems() 86 { 87 return QSpiAccessibleCacheArray(); 88 } 89 90 QT_END_NAMESPACE 91 #endif //QT_NO_ACCESSIBILITY 92
