DCOPExObj provides all of the necessary machinery to DCOP-enable
|
|
an application: the 'process' method, marshalling/demarshalling,
|
|
and the 'features' method
|
|
|
|
To DCOP-enable an app,
|
|
|
|
1. Add a class which subclasses DCOPExObj (ParrotObject in
|
|
this case). Call the DCOPExObj.__init__ method with 'id'.
|
|
If 'id' isn't specified, DCOP will assing a numerical id.
|
|
'id' is the name of the object (eg, how it will be listed
|
|
in kdcop, or returned with a dcopClient.remoteObjects call)
|
|
|
|
2. Identify the methods/functions that will be exposed via
|
|
DCOP - they don't have to be methods of the DCOPExObj
|
|
class, as long as the DCOPExObj class can call them. Make
|
|
sure they take/return types that DCOPExObj supports.
|
|
|
|
3. For each method, call self.addMethod with the complete
|
|
method signature (return type, name, list of argument
|
|
types, but no argument names) as a string and the
|
|
Python method/function that corresponds.
|
|
|
|
4. That's it.
