hi Felix
i m writing a personal mail, as my post is not being accepted by mailing list
though i have subscribed to it many times.
i want to ask, how can i access g_signal_connect_* family of APIs from
python
do i need to write a c code that will act as a callback for signal handler, and
in that c code i will call python functions
i mean to say, i have a class which registers certain signals using
g_signal_new
and i have to use g_signal_connect to register a callback function.
Now i am generating python bindings for this class, but i m not sure about
how to register callback functions that will be written in python.
should i provide a wrapper function which will take python object as argument
and will
internally register a dummy signal callback function using g_signal_connect.
this dummy function will than provide a mechanism to call python code from C
code.
ie to say
from python i will call a function as
defs p:
...
...
demo.register_callback(p)
this will call wrapper function register_callback which looks like
static PyObject *
_wrap_register_callback(........)
{
.......
PyArg_ParseTuple(); //----> conversion from python to C
g_signal_connect(..,..,GCALLBACK(dummy),....)
.....
}
and in dummy function i will write the code to call python function "p"
will this be OK or is there any other method
bye
