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;


and I use it in a slot:



public Q_SLOTS:
QString sayHelloWorld(MyStruct arg);


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"/>


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)
- I defined the
QDBusArgument &operator<<(QDBusArgument &argument, const MyStruct &arg); and
const QDBusArgument &operator>>(const QDBusArgument &argument, MyStruct &arg); operators
- BUT when I want to register my structure on dbus with
qDBusRegisterMetaType<MyStruct>, I'm getting an error:


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

What's wrong ?

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

Thanks for all

your 2nd problem:

qDBusRegisterMetaType<mynamespace::MyStruct>

this was working 4me

I tried your tips but this does not work anymore... :crying:

I'm working with Qt 4.5.0. Everything seem to be fine in my code according to several tutos or whatever but I'm still blocked by this error :mad:
