the args passed in are currently always empty for the DataEngine
constructor.
perhaps the misunderstanding here is that there is only ever one instance of
the DataEngine loaded, and that one engine hosts multiple sources of data.
information such as the to/from language should be encoded in the source
name, e.g. en:de:flower (which might have as its data: Blume). the
DataEngine would process these requests in sourceRequestEvent.
Thank you Aaron, It's working now (using absolute path to the script file!) :)
I'm trying to add Plasma::Package support to the dataengine, but...
there is another problem here! I've inherited from Plasma::PackageStructure
(Just like comic_package in comic dataengine)... but I still can't install my
translator plugin with plasmapkg:
Could not find a suitable installer for package of type Plasma/Translator
I think there is a problem in my CMakeLists.txt file I'm not sure though!
(there is no good tutorial on plasma packages too! at least I couldn't find any
in techbase!)
btw, this is my CMakeLists file:
project(plasma-translator)
find_package(KDE4 REQUIRED)
include(KDE4Defaults)
add_definitions (${QT_DEFINITIONS} ${KDE4_DEFINITIONS})
include_directories(
${CMAKE_SOURCE_DIR}
${CMAKE_BINARY_DIR}
${KDE4_INCLUDES}
)
set(translator_engine_SRCS translator-engine.cpp translator.cpp)
kde4_add_plugin(plasma_engine_translator ${translator_engine_SRCS})

${KDE4_KROSSCORE_LIBS})

Hi!
I've written a translation dataengine... It needs 3 arguments to initialize
