Working with QDBus and custom types

[JuBe]

Hi all,

I'm trying to get a small Qt apps working with DBus but there are some details I cannot find anywhere (perhaps I'm not looking after the right key words...)

1st.
In my app.h, I declare a structure:

typedef struct s_MyStruct{
QString s;
int i;
} MyStruct;

typedef struct s_MyStruct{
QString s;
int i;
} MyStruct;

To copy to clipboard, switch view to plain text mode 

and I use it in a slot:

public Q_SLOTS:
QString sayHelloWorld(MyStruct arg);

public Q_SLOTS:
QString sayHelloWorld(MyStruct arg);

To copy to clipboard, switch view to plain text mode 

But when I use qdbuscpp2xml to generate the xml dbus interface of this application/service, this method using a structure does not appear whereas DBus has a structure type.

I found that I can add this by hand like this:

<method name="sayHelloWorld">
      <arg type="s" direction="out"/>
      <annotation name="com.trolltech.QtDBus.QtTypeName.In0" value="MyStruct"/>
      <arg name="c" type="(si)" direction="in"/>

<method name="sayHelloWorld">
      <arg type="s" direction="out"/>
      <annotation name="com.trolltech.QtDBus.QtTypeName.In0" value="MyStruct"/>
      <arg name="c" type="(si)" direction="in"/>

To copy to clipboard, switch view to plain text mode 

I did not find any doc on Trolltech website for this so, where all of this is documented ?


2nd.
My second problem is when I'm trying to compile my application.
- I defined my structure to Qt MetaType with the macro:

Q_DECLARE_METATYPE(MyStruct)

Q_DECLARE_METATYPE(MyStruct)

To copy to clipboard, switch view to plain text mode 

- I defined the

QDBusArgument &operator<<(QDBusArgument &argument, const MyStruct &arg);

QDBusArgument &operator<<(QDBusArgument &argument, const MyStruct &arg);

To copy to clipboard, switch view to plain text mode 

and

const QDBusArgument &operator>>(const QDBusArgument &argument, MyStruct &arg);

const QDBusArgument &operator>>(const QDBusArgument &argument, MyStruct &arg);

To copy to clipboard, switch view to plain text mode 

operators
- BUT when I want to register my structure on dbus with

qDBusRegisterMetaType<MyStruct>

qDBusRegisterMetaType<MyStruct>

To copy to clipboard, switch view to plain text mode 

, I'm getting an error:

qmetatype.h:189: error: 'qt_metatype_id' is not a member of 'QMetaTypeId<s_MyStruct>'

qmetatype.h:189: error: 'qt_metatype_id' is not a member of 'QMetaTypeId<s_MyStruct>'

To copy to clipboard, switch view to plain text mode 

What's wrong ?

Please, help me! Where is all of this well documented ?

Thanks for all
