How does one expose methods and properties on DBus using a QDBusAbstractAdaptor with PyQt4?

问题 I am trying to get some basic code running on DBus using PyQt4, specifically QtDBus. I am using a Python3 version of PyQt4. I have already gotten the code I want running on Qt (c++) but I want to get similar code running using only Python. I want to expose Methods, signals/slots and properties on DBus for other Python code to call. In Qt you use the Q_CLASSINFO macro/function to do DBus introspection. While I have pulled in the Q_CLASSINFO method, i can't get it to produce the same type of

问题 I can run my Qt DBus test by connecting to the session bus: QDBusConnection connection = QDBusConnection::sessionBus(); connection.registerService(...) .... TestserviceInterface testserviceInterface( .... , connection, &a); But can I connect to this DBus from a different computer. I know I can do something like this: connection = QDBusConnection::connectToPeer("tcp:host=127.0.0.1,port=45000", Testservice::ServiceName); But how would I obtain the port? Whatever I have tried, there seems to be

问题 It's a confusing situation i'm in. While testing state transitions for a QStateMachine, the following code fails to spy on the signal that causes the transition. // Test transition to SS_STARTING QSignalSpy spy(test_obj_, SIGNAL(StateChanged(int))); // emmit StateChanged signal test_obj_->SetState(SS_STARTING); // Current state property should be SS_STARTING QVERIFY(spy.wait()); //<--- fails test QVERIFY(test_obj_->GetCurrentState() == SS_STARTING); QCOMPARE(spy.count(), 1); The following

问题 I develop an application in C++ on Linux, which interacts with blueooth devices (such as bluetooth sockets or speakers). I use D-Bus command to get list of paired devices: dbus-send --system --dest=org.bluez --print-reply $BTADAPTER org.bluez.Adapter.ListDevices It returns: method return sender=:1.0 -> dest=:1.90 reply_serial=2 array [ object path "/org/bluez/489/hci0/dev_00_1F_C5_75_45_5E" object path "/org/bluez/489/hci0/dev_F0_13_C3_00_A1_08" object path "/org/bluez/489/hci0/dev_00_11_12

问题 I am trying to create a daemon service that runs on the system bus where the permissions for sending and receiving from this service should be completely open to anybody. (Security is not a concern for this service). When I attempt to register the service using QtDbus (using the PyQt for it) I get this error: Connection ":1.0" is not allowed to own the service "org.dbus.arduino" due to security policies in the configuration file . This other stack overflow has the same error, but does not

How do I extract the returned data from QDBusMessage in a Qt DBus call?

I'm trying to call WPA supplicant's DBus interface using Qt's QDBus class library. In particular, I'm trying to use the "Get" property call to retrieve the "Interfaces" property value. The DBus specification (via introspection) for "Get" is: <interface name="org.freedesktop.DBus.Properties"> <method name="Get"> <arg name="interface" type="s" direction="in"/> <arg name="propname" type="s" direction="in"/> <arg name="value" type="v" direction="out"/> </method> ... </interface> Seems simple enough. Two strings input and the output is a variant (these are DBus types). For the "Interfaces" property
