DBUS服务器端程序

DBus 服务器端接收方式 DBus 服务器端用来接收signal和method调用。从收集的资料中发现，主要有三种接收方式。 一，采用while循环，监听dbus_connection_read_write()函数。有消息到来时在循环内部进行处理。优点是结构简单，处理方便。程序结构如下图。 /* test.signal.server(bus name) | ----test.signal.Type(interface1) | | | ----FunctionOne(method1) | | | ----FunctionTwo(method2) ----org.freedesktop.DBus.Introspectable(interface3) | | | ----Introspect(method3) response to interface(test.signal.Type) signal(Test) response to interface(test.signal.Type2) signal(TestString) response to interface(test.signal.Type) signal(MulType) */ #include <iostream> #include <stdlib.h> #include <dbus/dbus.h>

问题 Suppose I have a method like this <interface name="org.Test.ChildTest"> <!-- set_age(guint32 new_age): sets new age --> <method name="set_age"> <arg type="u" name="new_age" direction="in"/> </method> In my table of methods I have: { (GCallback) child_test_set_age, dbus_glib_marshal_child_test_BOOLEAN__UINT_POINTER, 0 } and the right GObject method signature is: gboolean child_test_set_age (ChildTest *childTest, guint ageIn, GError** error) Why does my method, child_test_set_age() , still get

How can I run a Perl script as root yet still affect user gconf settings

问题 THE NEW QUERY: I am trying to make a unified script that initializes a new Ubuntu install to my liking, it must be run under sudo to install packages, but using gconftool-2 to affect gconf setting relies on the dbus session which is not handled properly by the method of simply changing UID in the script alone. Does someone know how to manage to do this? OLD QUERY: I am writing a Perl script to be executed on first boot of a new Ubuntu install. This is to ease adding repositories, installing

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 to continuously monitor rhythmbox for track change using python

由 ╄→гoц情女王★ 提交于 2019-12-18 17:34:07
问题 I want to monitor the change of track in Rhythmbox using python. I want to continuously check for change of track and execute a set of functions if the track is changed. I have written a piece of code which gets hold of the Rhythmbox interfaces from the dbus and gets the current track details. But this program has to be run manually to check for any change. I am new to this and I would like to know how we can create a background process which continuously runs and checks Rhythmbox. I dont

Start systemd service from C/C++ application or call a D-Bus service

问题 I have a .service for a process that i don't want to start at boot-time, but to call it somehow from another already running application, at a given time. The other option would be to put a D-Bus (i'm using glib dbus in my apps ) service file in /usr/share/dbus-1/services and somehow call it from my application. Also, i don't manage to do this either. Let's say that my dbus service file from /usr/share/dbus-1/services is com.callThis.service and my main service file from /lib/systemd/system

问题 I am trying to get a notification when pluging in a USB device, for this I use a udev rule to track the moment it is pluged and from there I launch a script. The idea on the script was to use what it is explained in the link. but when trying this: pids=`pgrep -u $user gnome-panel` I found that gnome-panel is not there. Googled this work arround and I found quite few people complaining that this work arround is no longer working. So I did a bit of research on the subject and came up with this
