in that case, the DataEngine would create multiple key/value entries. however, what i would really recommend is doing it the way that the Share engine does it: * one source per service, e.g. youtube * implement serviceForSource, wich the applet uses to get a Plasma::Service object which does the actual query this will end up being a much more natural feeling result in the code. however, if you want to just make a youtube thing, you could just as well start by using the HTTP Javascript API extension: http://techbase.kde.org/Development/Tutorials/Plasma/JavaScript/API#HTTP and do it all in your script itself. for parsing xml, there is: http://xmljs.sourceforge.net/ i'd recommend using a DataEngine approach if you were going to do a multi- source (e.g. youtube, blip, etc. etc.) system which could then be more easily re-used by other plasmoids .. which is exactly what the Plasma MediaCenter people were doing, though i don't know what the status of those DataEngines are at this point. it would be quite possible to write the entire engine in JavaScript using JavaScript addons with the addons providing the Service objects and speaking html to the web service. > The dataengine will just give infos to the applet : url of the video, > image... that means the applet needs a to get the data via KIO?? no; create a VideoWidget and then set the url on it. it will handle the rest. > What is the "recommanded" language to write dataengines?? javascript is a good choice, but often c++ is required. > Is it better to separate the dataengine and the applet sources or place them > in the same "package"??? depends if the DataEngine is meant to be re-used or not. -- Aaron J.
