While using the qdbusxml2cpp program to convert the following xml to a Qt Class, I am getting this error: qdbusxml2cpp -c ObjectManager -a ObjectManager:ObjectManager.cpp xml/object_manager.xml Got unknown type `a{oa{sa{sv}}}' You should add <annotation name="com.trolltech.QtDBus.QtTypeName.Out0" value="<type>"/> to the XML description D-Feet description: XML: <!DOCTYPE node PUBLIC "-//freedesktop//DTD D-BUS Object Introspection 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/introspect.dtd"> <node><interface name="org.freedesktop.DBus.Introspectable"><method name="Introspect"><arg

I am writing a Java app to shutdown my Linux box remotely. The desktop app sits and waits for a command to be sent to it. I have tried using "shutdown -h" but this requires sudo privileges and is not an option. I then found a way to shutdown without sudo using the following dbus-send solution: dbus-send --print-reply --system --dest=org.freedesktop.Hal /org/freedesktop/Hal/devices/computer org.freedesktop.Hal.Device.SystemPowerManagement.Shutdown This works fine but I am trying to figure out, using dbus-send, if its possible to do a timed shutdown similar to "shutdown 3600" which would shut

When I run the Qt Creator dbus examples, they couldn't run, is there any settings or stuff for working QtDbus module or any prerequistics? for example in chat project: if (!QDBusConnection::sessionBus().isConnected()) { qWarning("Cannot connect to the D-Bus session bus.\n" "Please check your system settings and try again.\n"); return 1; } returns 1 and program terminated. Finally I found the solution: For QtDbus module get working, The 3rd party Dbus module must be installed in Windows: Dbus Windows Installer Download After downloading and installing Dbus, it gets working without any

I am trying to run the following example code using my NetBeans IDE: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <dbus/dbus.h> int main() { DBusConnection *connection = NULL; DBusError error; char buffer[1024]; dbus_error_init(&error); connection = dbus_bus_get(DBUS_BUS_SESSION, &error); if (dbus_error_is_set(&error)) { fprintf(stderr, "%s", error.message); abort(); } puts("This is my unique name"); puts(dbus_bus_get_unique_name(connection)); fgets(buffer, sizeof(buffer), stdin); return 0; } From an excellent tutorial: DBUS TUTORIAL USING THE LOW-LEVEL API I have my

I am working with QDBUS which has the custom type as Enum. After googling I found below link which explains marshalling of QDBUS custom types. http://techbase.kde.org/Development/Tutorials/D-Bus/CustomTypes#Adventurous_serialization_of_enumerations This doesnot explain the annotation to be specified in the QTDBUS interospection xml to generate proxy using qdbusxml2cpp. How to add Enum annotations in QTDBUS interospection xml? Please if possible explain with some sample code. I found a solution for my problem: First create a new header file called enums.h which looks like: #ifndef ENUMS_H

The problem I am having is specifically printing out the response of a dbus method call in C using the low level API. I am new to C's libdbus, but have done some work in python-dbus. I know how to write dbus methods and method calls in python as well as the CLI I can find code on the internet to invoke dbus methods, but they don't return or print out the response I have been looking at the libdbus doxygen api, but cannot determine how to pull out the response. The way I have my code set up, a python dbus daemon runs with methods I want to call. Some of them return a string. I want a C program

I'm about to work on an implementation of mpris . But currently I am not sure how to read/write dbus interface properties with python-dbus. Is there any examples for this ? Finally got the answer: @dbus.service.method(dbus.PROPERTIES_IFACE, in_signature='ss', out_signature='v') def Get(self, interface, prop): ... @dbus.service.method(dbus.PROPERTIES_IFACE, in_signature='ssv') def Set(self, interface, prop, value): ... @dbus.service.method(dbus.PROPERTIES_IFACE, in_signature='s', out_signature='a{sv}') def GetAll(self, interface): ... 来源： https://stackoverflow.com/questions/4277814/how-to

I need an IPC system on Linux. My requirements are: packet/message oriented ability to handle both point-to-point and one-to-many communication no hierarchy, there's no server and client if one endpoint crashes, the others must be notified good support from existing Linux distros existence of a "bind" for Apache, for the purpose of creating dynamic pages sorted in order of importance (roughly). I don't need extreme performance, nor I will be sending high volume of data. I stumbled upon DBus, and it looks like a good candidate (it pecl::packages::dbus a good mechanism to let Apache access the
