Messaging system update .... soon ;)

[Christian Reiniger <warewolf@mayn.de>]

Hi all,

The Gtk-- team is currently working to make the signal/slot system handle return values correctly. The mods should appear
somewhere around version 0.9.6 (seems as if they have some problems making it work correctly with the Gtk+ signal interface).
IŽll incorporate the changes into our system ASAP.

For the curious here - it will look somehow like this:

-------------------------
template <class rettype>
class DecisionMaker
{
public:
    virtual bool CallNext (rettype PreviousRetVal) = 0;
    rettype RetVal (void) = 0;
};

class MyDecider : public DecisionMaker <int>
{
private:
    int RetValUpToNow;
public:
    bool CallNext (int RV)
    {
        RetValUpToNow += RV;
        return ((RV > 50) ? true : false);
    }

    int RetVal (void)
    { return RetValUpToNow; }        
};


rettype ppMessage0::call (...)
{
    while (anotherHandlerExists)
    {
        if (!Decider.CallNext (Handler ()))
            return (Decider.RetVal ());
    }
}
-----------------------------
