1) I have never tried with default arguments so I don't know what problems that
may introduce.

2) I setup the pointer with "printOffset = &CHexBuffer::printDummyOffset;"
In your case currentFunction = &SomeStuff::f1;

3) What do you mean by "doesn't work" ?

4) If you can compile khexedit (cvs or kde 1.1.x version) then you use function
pointers. Have a look in hexbuffer.cc + h to see how it is done.
