[Qt-creator] Symbol visitor and Scope::Use questions

[Bertjan Broeksema]

Hi Roberto,

We implemented a Symbol visitor and when we visit a block we execute the 
following code:

bool SymbolTreeModel::visit(CPlusPlus::Block *block)
{
  for (unsigned i = 0; i < block->memberCount(); ++i)
  {
    Symbol *member = block->memberAt(i);
    accept(member);
  }
  
  return true;
}

However, if we use this code for this small example:

int main(int argc, char *argv[])
{
  string s = "een string";
  s += " meer tekst";
  cout << s << endl;
  
  return 0;
}

it seems that there is only a child node for the declaration of s in the 
block. The semantic pass doesn't seem to add child nodes to the block for the 
Expressions which are in the block. Could you explain why this happens and how 
we eventually could solve this?

Another question we had is about the Use class in Scope. What exactly is the 
purpose of this class? Does it define the relation definition <-> use?

Cheers,

p.s. Debugging in QtCreator works like a charm. Nice work!
