		From technical point of view DCOP is a interprocess communication protocol operating over sockets.
		This is because DCOP communicates with process and not with application.
		You probably won't use it for actual DCOP calls (except for testing) as it does not really make much sense to use GUI application to send signals to tell other GUI application to do something, you could have done directly inside that application.

	Scripting onder KDE met DCOP
		DCOP is een zeer krachtige, maar ook eenvoudige manier om KDE-toepassingen te manipuleren.
		We laten nog een voorbeeld zien waarbij we JuK, KAlarm en uiteraard DCOP gebruiken.
		We zullen nu twee hele simpele voorbeelden laten zien hoe je DCOP kunt gebruiken binnen scipts.

	Desktop Communication Protocol (DCOP)
		DCOP provides inspection functions so that it is possible to browse DCOP interfaces in order to find out which interfaces are registered and which functions they provide.
		DCOP intentionally doesn't provide network transparent communication because this isn't required in normal desktop scenarios and would add an additional level of complexity as well as imposing a new class of security problems which don't need to be handled if network access is disabled.
		This way the DCOP call appears as normal type-safe function call to the calling application and the DCOP communication and the fact that the call actually is a remote function call becomes completely transparent to the applications using DCOP.

	Why aRts isn't using DCOP
		DCOP doesn't care about types at all, so this problem would be left to the programmer - like: writing C++ classes for the types, and make sure they can serialize properly (for instance: support the Qt streaming operator).
		DCOP objects don't expose their relationships, inheritance hierarchies, etc. - if you were to write an object browser which shows you "what attributes has this object got", you'd fail.
		But remember: DCOP was not so much intended to be an object model (as Qt already has one with moc and similar), nor to be something like CORBA, but to supply inter-application communication.

	DCOP: Desktop COmmunications Protocol
		DCOP is built on top of the Inter Client Exchange (ICE) protocol, which comes standard as a part of X11R6 and later.
		Currently the only real way to receive data from DCOP is to multiply inherit from the normal class that you are inheriting (usually some sort of QWidget subclass or QObject) as well as the DCOPObject class.
		DCOP signals are very similair to Qt signals, there are some differences though.

	Connect KDE applications using DCOP
		DCOP comprises a single server (dcopserver, which is started automatically when KDE starts) and any number of clients (DCOP-enabled applications).
		DCOP clients can send messages to each other (via the server) to request information, ask for functions to be performed, and so on.
		For clarity, from this point onwards, dcop in lower-case refers to the command-line utility, and DCOP in upper-case refers to the DCOP architecture in general.

	The DCOP Interface - K3b
		K3b comes with a quite usable DCOP interface which allows it to control K3b from another application or from a script.
		In the latter case this is done with the dcop command line tool.
		All createXXXProject and the currentProject methods return a DCOP reference to a K3b project through a K3bProjectInterface as described below.

	Using DCOP from the command line LG #97
		In this regard, DCOP is similar to Microsoft's OLE Automation: it provides a simple way for developers to provide access to the functions available in an application.
		This enables a range of applications, such as the DCOP browser, or the DCOP to XMLRPC daemon; but the one I'm going to look at is 'dcop', which allows shell access to DCOP.
		This article is about using DCOP to control KDE applications from the command line; links are provided at the end of the page to developer information for those who wish to delve deeper into this technology.

	KDE--The Next Generation \| Linux Journal
		DCOP is just a thin layer on top that handles the marshaling of data and makes sure all communication streams reach their destination.
		You can imagine DCOP as a traffic cop who stands in the middle of a road crossing and directs the cars into their lanes, so that everyone reaches their destination, no accidents occur and no passengers end up in the wrong cars.
		DCOP is used in KDE to unify the different communication means, like X atoms for communication between the control center and the application or TCP/IP sockets.

	Examples
		DCOP is KDE's acronym for it's "Desktop Communications-Oriented Protocol" - basically a lightweight and simple mechanism for inter-process communications (IPC).
		DCOP allows two running applications to exchange messages or other information or exercise control over each other.
		Accessing a DCOP method in another application requires 3 pieces of information: the name of the application to be accessed, the name of the DCOP object which holds the method to be called, and the name of the method itself.

	dcop server problems \| MEPIS (Site not responding. Last check: )
		The key feature of DCOP that makes it a viable choice for Kontact's inter-component communication is that it is also able to make in-process calls and thus minimizes the overhead for communication inside the one-process Kontact component assembly.
		DCOP is not limited to communication between applications.
		This makes it possible to hide parts of the DCOP interfaces, so that they can be used for inter-component communication, but are not available to tools like dcop and kdcop which rely on the interface inspection capabilities of DCOP.

		I can say that dcop is more integrated in KDE than DBUS is integrated in GNOME, but I can't say that DBUS is not integrated in GNOME.
		I don't mean that DCop is not powerful, but everyone (including KDE developers) seems to agree that DBus offers more, and I can't understand what that is.
		Which combined with performance is the really important factors regarding replacing DCOP with D-BUS, or have some sort of side-by-side use as it's done now.

		dcop is not a new breed of security concern.
		Dcop and dcopstart seems (as far as I can see) to be secure enough to not support an intruder to succeed.

	Description of DCOP's Programming Interface - Andamooka Reader (Site not responding. Last check: )
		Using many wildcards in DCOP communications is a bad idea, though, because it generates large amounts of IPC traffic.
		Situations may occur in which the connection with the DCOP server has to be deactivated temporarily.
		A DCOP client that wants to communicate via DCOP with the new smarter widget has only to include the published interface file (asmartwidget_stub.h).

	Why aRts Doesn't Use DCOP
		The result I got was that while DCOP got slightly more than 2000 invocations per second, MCOP got slightly more than 8000 invocations per second.
		With DCOP, that is not really intended, and as far as I know not really possible.
		Write an MCOP - DCOP gateway (which should be possible, and would make interoperation possible) - note: there is an experimental prototype, if you like to work on that.

		For more information look at http://developer.kde.org/documenta tion/library/2.0-api/dcop/HOWTO.html This Perl extension can be used to send commands to any currently registered DCOP application, as well as query which apps are registered and what interfaces with what functions they offer.
		The easiest way to establish a connection is $client->attach(); which registers your DCOP client anonymously.
		In scalar context, the value returned is the function's return value, in list context call returns a two element list with the first item set to the func tion's repturn value and the second set to true or undef according to success or failure of the DCOP call.

	DBUS and DCOP Hoopla (Site not responding. Last check: )
		DCOP may be good as an inter application message protocol for applications running in the same session.
		The point is that before we drag DCOP out to the curb with the coffee grounds and swear allegiance to DBUS we need to know that we have done the right thing by users...
		Because DCOP depends on X11 ICE it means you can't easily have a native Mac OS X version for instance, whereas with a sockets based ipc mechanism that's no problem.
