DBus signal connection problem

? Offline

Hi,

I upgraded from Ubuntu 9..04 to 11.10 and the following code started throwing an error:
@
m_hal_manager_p = new QDBusInterface( Hal::SERVICE, Hal::MANAGER_PATH,
Hal::MANAGER_IFACE, QDBusConnection::systemBus(), this );

(void)connect( m_hal_manager_p, SIGNAL( DeviceAdded( QString ) ),
    this, SLOT( OnDeviceAdded( QString ) ) );

@
Error:
@
Warning: Object::connect: No such signal QDBusAbstractInterface::DeviceAdded( QString ) in ../../../Components/Qt/4/ExternalStorage/VolumeManager.cpp:43
@
Any ideas what I might not have installed or configured properly to cause this?

Please "code wrappings":http://qt-project.org/wiki/ForumHelp#e3f82045ad0f480d3fb9e0ac2d58fb01 for your code. I have introduced them for you.

As the warning suggests the "signal is not defined. ":https://qt-project.org/doc/qt-4.8/qdbusinterface-members.html

Did you also upgrade from Qt3 to Qt4?
I doubt that in an earlier Qt4 version this signal was available.
