It should be. Can you tell us a little more? Is your slot called at all? If not, what error does the caller get when trying to call it? If so, is any warning printed after return?

When I build it with type "ao" in the ServiceData.xml file, I get this warning at runtime...


QDBusError("org.freedesktop.DBus.Error.InvalidSignature", "Unexpected reply signature: got "ao", expected "a(ss)"")

So I updated my xml file to read...

<!DOCTYPE node PUBLIC "-//freedesktop//DTD D-BUS Object Introspection 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/introspect.dtd"<http://www.freedesktop.org/standards/dbus/1.0/introspect.dtd>>
<node>
  <interface name="com.GDM.ServiceData">
    <method name="serviceErrorLog">
        <arg name="serviceErrorLogData" type="ao" direction="out"/>
    </method>
  </interface>
</node>

When I change the xml file to have a(ss) as the type instead of ao, qtcreator shows a build error that suggests I need to add the following...

You should add <annotation name="org.qtproject.QtDBus.QtTypeName.Out0" value="<type>"/> to the XML description

So I updated my xml file to look like this...

<!DOCTYPE node PUBLIC "-//freedesktop//DTD D-BUS Object Introspection 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/introspect.dtd"<http://www.freedesktop.org/standards/dbus/1.0/introspect.dtd>>
<node>
  <interface name="com.GDM.ServiceData">
    <method name="serviceErrorLog">
        <arg name="serviceErrorLogData" type="a(ss)" direction="out"/>
        <annotation name="org.qtproject.QtDBus.QtTypeName.Out0" value="ServiceErrorLogData"/>
    </method>
  </interface>
</node>

and I got this warning...


servicedata_adaptor.cpp:36:1: error: 'ServiceErrorLogData' does not name a type

ServiceErrorLogData ServiceDataAdaptor::serviceErrorLog()

^

make[1]: *** [servicedata_adaptor.o] Error 1

So I tried to change it to <QList>ServiceErrorLogData and I got...

Got unknown type `a(ss)'

You should add <annotation name="org.qtproject.QtDBus.QtTypeName.Out0" value="<type>"/> to the XML description

make[1]: *** [servicedata_adaptor.h] Error 1

make: *** [sub-DataProcess-DataProcess-pro-make_first] Error 2

16:11:10: The process "/usr/bin/make" exited with code 2.

Error while building/deploying project dbustest (kit: MEL Qt 5.2.1)

When executing step 'Make'

What should I set the <Type> to in the xml file? Thanks!
