Creating a DBus Adaptor from inside his object
Message 1 in thread
Hi,
Why if I instantiate a QDBusAbstractAdaptor object from *inside* the
object his referencing I cannot see the interface ?
Following the code.
If the symbol FROMINSIDE is NOT defined, the program works well:
happycactus@lama:~/Progetti/TecnoMare/Rotis2> qdbus
com.studiofuga.test /test
property read QString com.studiofuga.test.name
signal void com.studiofuga.test.crashed()
method QString com.studiofuga.test.getName()
method void com.studiofuga.test.ping()
method void com.studiofuga.test.setName(QString val)
method void com.studiofuga.test.test()
method QDBusVariant org.freedesktop.DBus.Properties.Get(QString
interface_name, QString property_name)
method void org.freedesktop.DBus.Properties.Set(QString interface_name,
QString property_name, QDBusVariant value)
method QString org.freedesktop.DBus.Introspectable.Introspect()
if the FROMINSIDE is defined, it doesn't work as expected:
happycactus@lama:~/Progetti/TecnoMare/Rotis2> qdbus
com.studiofuga.test /test
method QDBusVariant org.freedesktop.DBus.Properties.Get(QString
interface_name, QString property_name)
method void org.freedesktop.DBus.Properties.Set(QString interface_name,
QString property_name, QDBusVariant value)
method QString org.freedesktop.DBus.Introspectable.Introspect()
As you can see, the methods are missing.
I am wondering if I am missing something...
Thank you in advance!

ing. Federico Fuga

Ok, Ok. I have spent three hours to solve this issue, before seeing 30
seconds after sending the post that I am registering the adaptor, NOT
the object he is referring to.
I really and urgently need a vacation.
Thank you again.
