Member Function Pointer in Qt C++

typedef void (classname::*funptr)(int);

void classname::func(int p)
{
...
}

void classname::someotherfunc()
{
........

 funptr ptr;
 ptr= &(classname::func);                 // this is error line 

...........
}

It gives me the following error:

error C2276: '&' : illegal operation on bound member function expression.

Next I tried

ptr= classname::func;

which gives this error:

error C3867: 'FaceBinUI::progress_update': function call missing argument list; use '&FaceBinUI::progress_update' to create a pointer to member

Please suggest some solution for this problem.

The compiler is telling you exactly what you need to do:

ptr= &classname::func;

So just lose the parentheses.
