RE: Using g_signal_connect in class

["Vallone, Anthony" <anthony vallone lmco com>]

Only if the member function is static.  Calling a non-static member
function requires two addresses: the instance address and the function
address.  Whether its public or private doesn't matter because access to
function pointers is not checked by compilers.  I frequently do
something like this:

class SomeClass
{
  ...
private:
  ...
  static void staticCb(..., gpointer inInstance) {
    SomeClass* instance = (SomeClass*)inInstance;
    instance->callback(...);
  }
  void callback(...) {
    ...
  }
  ...
  void someFunc() {
    ...
    g_signal_connect(..., G_CALLBACK(&staticCb), this);
    ...
  }
  ...
};
