Inherit + Method Pointer

[Bleast]

Hello,

I have a mother class like that (I keep only the interessting part) :
Code :


namespace ZenZiAPI
{
class IModule
{
public:
typedef bool (IModule::*p_callback)(ITools&);
}
}


And a son class with two functions like that (The functions are simplified):
Code :


bool ModulePHP::GetPHP(Tools &_EOTools)
{
return (true);
}

const std::vector<std::pair<ZenZiAPI::IModule::p_callback, ZenZiAPI::hookPosition>>& ModulePHP::getCallbacks()
{
this->_LPHook.first = static_cast<ZenZiAPI::IModule::p_callback>(&ModulePHP::GetPHP);
}


The Error is on this lign :
Code :


static_cast<ZenZiAPI::IModule::p_callback>(&ModulePHP::GetPHP);


Compilation error :

Error 4 error C2440: 'static_cast' : cannot convert from 'bool (__thiscall ModulePHP::* )(Tools &)' to 'ZenZiAPI::IModule::p_callback'

I spent the day trying to find it out, somone knows what i can do ?

Thanks !

You can't cast pointers to functions.

Ah yes, this problem.

The problem is that your p_callback typedef can only be used for pointers to member functions of IModule, and not of any of its descendants.

You should very seriously look into boost::function and boost::bind as a much better callback mechanism.
