Hello all,

I'm improving callback implementation in pkg-bindings,
I'd like to add a total progress and the callbacks should be displayed
in the main dialog (instead of popups).

I'm reusing zypp::ProgressData class with zypp::CombinedProgressData class which
provides a sub progress for a sub task. That's nice.

But I have a problem, I can register only
  bool function(const zypp::ProgressData&)
as the receiver function, I'd like to register
  bool MyClass::function(const zypp::ProgressData&)

Is it possible somehow? Maybe I'm not using the classes correctly...



Currently I'm using this really ugly hack (a global pointer):

PkgModuleFunctions *ptr = NULL;

bool source_receiver(const zypp::ProgressData &progress)
{
    if (ptr != NULL)
    {
        return ptr->SourceLoadReceiver(progress);
    }

    return true;
}

bool PkgModuleFunctions::SourceLoadReceiver(const zypp::ProgressData &progress)
{
  // handle the progress here...
}


YCPValue PkgModuleFunctions::SourceLoad()
{
    ptr = this;
    YCPValue ret = SourceLoadImpl(source_receiver);
    //                            ^^^^^^^^^^^^^^^^^^
    // here I'd like to use PkgModuleFunctions::SourceLoadReceiver
    return ret;
}


PkgModuleFunctions::SourceLoadReceiver doesn't work for this reason:

Source.cc: In member function 'YCPValue PkgModuleFunctions::SourceLoad()':
Source.cc:442: error: no matching function for call to
'PkgModuleFunctions::SourceLoadImpl(<unresolved overloaded function type>)'
./PkgModuleFunctions.h:180: note: candidates are: YCPValue
PkgModuleFunctions::SourceLoadImpl(const boost::function<bool ()(const
zypp::ProgressData&), std::allocator<void> >&)


See the latest SVN version of pkg-bindings for more details...


        Thank you in advance
