Re: [e-users] Problem using boost::bind and ecore_ipc from Enlightenment
Before i posted to the List, i already managed too bind the Non-Member
Functions to the Handler (e.g. ecore_event_handler_add)
int Test( void *d, int t, void *e ) { return 0; }
ecore_event_handler_add( ECORE_IPC_EVENT_SERVER_DEL, Test, NULL );
I think it's the same in Factory.*.
My Problem is, if i have a class and a Memberfunctions Test like the one above,
i can't right of it. ( xnowfall tells us a plausible Reason why it doesn't fit
like i tried it )
This Version would look like
int
ClassA::Test( void *d, int t, void *e ) { return 0; }
ecore_event_handler_add( ECORE_IPC_EVENT_SERVER_DEL, CannotBindIt, NULL );
CannotBindIt: ClassA::Test, ClassA-Test, bind...(...)
Nothing worked.
I guess this Example from avisynth is for Non-ClassMember Functions, or am i
wrong?
Greets,
Christian

Re: [e-users] Problem using boost::bind and ecore_ipc from Enlightenment
Can't you wrap ecore objects with a boost::smart_ptr ? I use the smart_ptr to wrap objects of the Gstreamer library without any problem. After that, I think it is not difficult to use the C++ stuff of boost. For examples, maybe you can have a look there: http://cvs.sourceforge.net/viewcvs.py/avisynth2/avisynth/src/gstreamer/?only_with_tag=avisynth_3_0 Hope this helps Vincent On Sun, 31 Jul 2005, xnowfall wrote: ecore_* takes a pointer to a function whereas boost::bind returns an object (that can be used as a function by operator overloading). to use a member function you need both a pointer to an object instance and a pointer to the function, which boost::bind wraps up in an object, but which the efl can't use. it would be nice to use stuff like boost::bind, but that's a c++ thing and the efl is c --- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.

[e-users] Problem using boost::bind and ecore_ipc from Enlightenment
Hi all,
I have a Problem with C++ Member Functions and Pointers to this Member
Functions so that they fit into a Function with take a normal Function.
I guess i'm a Newbie, otherwise i should have already solved it, i think. ;)
I want to use IPC Stuff from Ecore. But before you can make use of ecore_ipc
you must initialize it, as far as i can see.
I atached 4 Files, where i build a little Scenario:
1. Example.cpp // The Main Program
2. Testclass.hpp
3. Testclass.cpp
4. Makefile // Perhaps you must adjust some of the Variables
I commented the important Points in the Code again.
So i must first call
ecore_ipc_init() // Testclass Line 68
and
must supply 3 Functions to ecore for handling Events
1. A Function that is called, when a new IPC Server is added
2. A Function that is called, when a IPC Server is deleted
3. A Function that is called, when some Message is sent
Namely:
ecore_event_handler_add( ECORE_IPC_EVENT_SERVER_ADD, ipc_server_add, NULL );
ecore_event_handler_add( ECORE_IPC_EVENT_SERVER_DEL, ipc_server_del, NULL );
ecore_event_handler_add( ECORE_IPC_EVENT_SERVER_DATA, ipc_server_data, NULL );
ipc_server_add, ipc_server_del and ipc_server_data are the functions that
are available outside the Class Testclass
The Example Program as it is compiles and i can start it, the ecore_pic_init()
succeds the 3 Functions get registered but this 3 submitted Functions are
standing outside my Testclass,
but my Target is to have they inside my Testclass.
That's my Problem, i didn't get the Clue to give these MemberFunctions to these
3 Functions:
ecore_event_handler_add( ECORE_IPC_EVENT_SERVER_ADD, ipc_server_add, NULL );
ecore_event_handler_add( ECORE_IPC_EVENT_SERVER_DEL, ipc_server_del, NULL );
ecore_event_handler_add( ECORE_IPC_EVENT_SERVER_DATA, ipc_server_data, NULL );
I tried Things like that, but that didn't helped me:
ecore_event_handler_add( ECORE_IPC_EVENT_SERVER_DEL, boost::bind(
boost::typeint(), Testclass::ipc_server_add ), NULL );
ecore_event_handler_add( ECORE_IPC_EVENT_SERVER_DEL, boost::bind(
boost::typeint(), Testclass::ipc_server_add, _1, _2, _3 ), NULL );
So i want to ask to the Mailinglist in Hope somebody knows how to do this Task
in the right Way. ;)

Re: [e-users] Problem using boost::bind and ecore_ipc from Enlightenment
i'm not sure how you mean to use a smart_ptr - maybe we're talking about different things here? a smart_ptr is also an object and can't be passed to a function expecting a function pointer. as for the example, i'm guessing you mean the SignalHandler class? i don't really see the point of that template at all; have you tried calling that constructor with anything other than a function for the CallBack type?
