My code just like:
QDBusMessage message = QDBusMessage::createMethodCall("org.nemomobile.lipstick",
"/org/nemomobile/lipstick/screenshot",
"org.nemomobile.lipstick",
"saveScreenshot" );
QDBusConnection conn = QDBusConnection::sessionBus();
conn.send(message);
But it still block the UI ( screen will not response within a few seconds)
Please help!Thanks very much.
