DDE, OLE and OpenDoc?
by testerus on Monday 05/Jun/2006, @18:49

What is the difference to Dynamic Data Exchange and Object Linking and Embedding in the Windows world? Or OpenDoc on the Mac?

DDE is an interprocess communication control. Like DCop or D-Bus
It's not the same as Flake.

Flake lets you edit objects (created with another program) from inside a single program. So you only run one process.

I guess you can compare it a little with OLE, but it still is not the same.
Editing a spreadsheet from within KWord for example doesn't load the whole KSpread program. Only those tools or shapes that are needed.

DDE was a very cool thing just as DCOP is today. I'm not as familiar with OpenDoc but I believe it is an embedding framework. OLE stood for Object Linking and Embedding, but it ended up meaning "One Long Expletive" when it crashed trying to do anything useful. When I left Windows in the 90s focus had shifted from DDE to OLE because MS preferred bloated embedding protocols to scripting. KDE's KParts and the Koffice libraries are more efficient, but the libraries you mentioned are more general purpose. For instance in Quanta we use KParts to load an application and DCOP to communicate with it. Compared to what Koffice is doing it's very rudimentary. Our interface is fairly rigidly defined to a full panel and we may find the plugin needs additional interfaces. With KOffice there is a lot more intelligent and defined interaction in the libraries inside.

On the subject of Quanta, is there going to be a KDE 4 port?

... I found that tool infinitely useful.
