[boost] Calling a python function from C++ to update a progress display widget

Let's say I have the following in a Python file called progress.py: 

 

pbar = gtk.ProgressBar()

 

def updateBar():

    pbar.puls()   

 

 

In C++:

 

for ( int i = 0; i < 10; i++ )

     // Call the python method updateBar() which is not a member of any
class in progress.py

 

 

How do I do it? I'm aware of the following 2 functions in boost:

 

call<ResultType>(callable_object, a1, a2... aN);
call_method<ResultType>(self_object, "method-name", a1, a2... aN);

 

Can I see an example on how to use them?

 

My goal is to display the progress bar widget live while the for loop is
counting from 0 to 9.
