As far as I can see serviceForSource() exists in the Ruby bindings and
should work:
$ rbqtapi -rplasma_applet -mserviceForSource
Plasma::Service* Plasma::DataEngineScript::serviceForSource(const QString&)
Plasma::Service* Plasma::DataEngine::serviceForSource(const QString&)
So we are calling in on an actual Plasma::DataEngine here, not a
DataEngineScript. If I this debugging print out the various items
created like this:
engine = dataEngine("tasks")
sources = engine.sources
pp engine
p sources
service = engine.serviceForSource(engine.sources[1])
pp service
p service.operationNames
close_description = service.operationDescription("close")
pp close_description
service.startOperationCall(close_description)
I get:
#<Plasma::DataEngine:0xa8ef8f3c
children=Array (15 element(s)),
metaObject=#<Qt::MetaObject:0x0 className=TasksEngine,
superClass=#<Qt::MetaObject:0x0 className=Plasma::DataEngine>>,
objectName=Window Information,
sources=nil,
valid=true,
icon=user-desktop>
["71303776", "65011736", "52428825", "60817446", "16777241",
"67108924", "69206018", "44040217", "37748765", "27262978",
"46137441", "58720281", "62914562", "71303343", "56623131"]
#<Plasma::Service:0xa8ef69e4
parent=#<TasksEngine:0x0 objectName="Window Information">,
metaObject=#<Qt::MetaObject:0x0 className=Plasma::Service,
superClass=#<Qt::MetaObject:0x0 className=QObject>>,
objectName=nil>
[]
#<KDE::ConfigGroup:0xa8ef52ec>
So is that Plasma::Service a dummy one? How can I tell? Is doesn't
seem to have got any operation names associated with it.
