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

For an example of implementation of callbacks with boost: http://cvs.sourceforge.net/viewcvs.py/avisynth2/avisynth/src/filters/source/gstreamer/?only_with_tag=avisynth_3_0 look at factory.* Vincent On Mon, 1 Aug 2005, Carsten Haitzler wrote: On Sun, 31 Jul 2005 22:08:37 +0200 Der Lockruf des Kaos [EMAIL PROTECTED] babbled: 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 Ok so i must use something else then i guess.

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.

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?
