for example, look at the declaration of FunctionDefinitionAST in  
AST.h. FunctionDefinitionAST has an attribute called "symbol", you can  
use that attribute to get the info you need from the symbol table  
(e.g. the function's scope, the function name, and so on..)

class MyVisitor: protected ASTVisitor {
  // ...

protected:
    virtual bool visit(FunctionDefinitionAST *ast) {
       Function *fun = ast->symbol->asFunction();
       qDebug() << "scope:" << fun->scope() << "name = " << fun->name();
       qDebug() << "coordinates:" << fun->line() << fun->column();
       return false;
    }
};
