Can anyone help me figure out this cryptic error?

[slugg]

Here's my typedef:
typedef int (*MouseCallback)(const Position &);


Line that I get the error:
windowList.back()->SetMouseClickCallback(graphicsList.back()->mouseClick);


The error:
: error C2664: 'SetMouseClickCallback' : cannot convert parameter 1 from 'int (const class Position &)' to 'int (__cdecl *)(const class Position &)'
None of the functions with this name in scope match the target type



^^ What? LOL! I really don't understand what that error means. Anyone have any idea?

Thanks for looking 🙂

Something is expecting a pointer as a parameter and not getting it.

You need to change your callback function prototype to either

typedef int (WINAPI *MouseCallback)(const Position &); or
typedef int (__cdecl *MouseCallback)(const Position &);
