Re: [sigc] conditions in libsigc

[Roel Vanhout <roel riks nl>]

If I understand what you describe correctly, I think it would be very 
useful, but only is it's not restricted to bool variables. I'd like to 
have a way to 'mark' a (member) variable (eg by wrapping it in a 
template) which would then automagically emit a signal when that 
variable is changed (that is what you're proposing, right?), but in my 
usecases that would hardly ever be a bool, more likely a string, numeric 
value or complex type. Then again, how would this work with complex 
types? Say:

class A
{
public:
  int m_Int;
}

class B
{
public:
  A m_A;
}

B.m_A.m_Int = 5;

Who should emit a signal - only m_Int or m_A also, because that object 
has changed, too?

I'm drifting away from the original question I'm afraid, I was just 
braindumping :)


cheers,
