[Qt-interest] qdbus (qt4.6) issue running on Unbuntu

[Wong, Carl]

I have an issue with qdbus and not sure if it is a bug in my code or in qdbus itself.

I have a remote method that takes 2 "In" parameters. Here is the xml snippet for the method:

    <method name="Sync">
        <arg type="s" name="mode" direction="in" />
        <arg type="a{ss}" name="sources" direction="in">
        <annotation name="com.trolltech.QtDBus.QtTypeName.In1" value="QStringMap"/>
    </method>


I have QStringMap define as follow:

       typedef QMap<QString, QString > QStringMap;
       Q_DECLARE_METATYPE ( QStringMap )

And I register the type by calling qDBusRegisterMetaType< QStringMap >()';

In my client code when I make a call to the remote method Sync, it failed and the error was bad signature.  I ran dbus-monitor and it show the following error:

       Method "Sync" with signature "sa{ss}" on interface "org.syncevolution.Session" doesn't exist

It appears to me that qdbus is not encoding the data correctly before send the request over the wire. Looks like it packed the 2 parameters into one. My question is do I have to create the "<<" and ">>" operators for my custom type QStringMap.  From what I read, I shouldn't have to since QStringMap is just a QMap<QString, QString >.   And I have no problem with the out parameter using the same custom type.

Any help would be greatly appreciated!!

Thanks,
Carl
